Silister Trench
- #1
I’ve been trying out a handful of LED’s for a few months now, making sure each tank is given an opportune regiment of fertilizers with proper filtration and low stocking to see just how well some of these “Cheap” or “Knock-off” LED’s hold up. I’d like to take a moment to explain why first. Well… it’s because in both old and new threads when members begin threads concerning LED’s our community seems to have a set of generic responses that we adhere to a straight forward question of: “Do you want High/Med/Low light plants?” That’s an excellent question intended to narrow down what seems like an almost endless list of lights sold in LFS (local fish stores), and even more so online given the two biggest e-commerce websites.
While the question is a strong one in determining what light will suit your needs our responses are generic, however, rightfully so. Why? Because once upon a time we browsed LED’s, then bought one and it worked in a way that met our expectation and we want to share our success with others. If you want to grow Anubias, Java [whatever], and most mosses well then essentially a Low Light/Low Tech setup is what the member inquiring is after, which is followed by our generic reply: “A Finnex Stingray is the light for you!” If you want want high light, a carpet, or enjoy trimming plants weekly then our response differs ever-so-slightly to a “Finnex Fugeray Planted +”, which in my personal opinion is a horrible solution to a lighting problem when you’re just starting out, even if the member new to LED’s or plants desperately needs that IwagumI carpet and has the funds to swing for the light + Co2 system every single one of them require. Having the level of PAR one of the Fugeray Planted + LED fixtures is capable of emitting in most entry level tanks is like taking a firecracker, lighting said fire cracker, then passing it to someone who’s never seen one. Despite my described accident waiting to happen, a lot of our LED light solutions are the same.
Low Light / Stingray
Medium Light / Stingray (what the measurement of PAR is actually on most tanks)
High Light / Finnex Planted +
I hated going with the Norm, so below is a review of some cheap solutions I quickly found on eBay as well as others. All are rated based on my overall experience with ***** up to 5 with 5 being perfect In my Opinionated Rating or o/R system.
* Beamswork EA Timer FSPEC LED Aquarium Light Freshwater Plant Extendable -
This light caught my attention almost right away. At first glance it seems like a cheap alternative to a stingray, and I will say that having 2x of 24” models above a 20 Gallon High take DID grow plants, despite having nowhere in the description found a single mention that this LED fixture was intended to grow plants.
GOOD It grew mosses and my Black Skirt Tetras really looked great in the light, giving off an almost shimmery violet effect at times. It was a wonderful light for fish. The fixture itself is a nice design, and the timer is pretty awesome.
BAD This light instantly stood out as a cheap alternative, but for $24 (another $14 - $20 additionally if you want to buy the timer too) it’s not a great deal. It’s low power (High Output, they claim) LED’s are dI'm which was why I had to use 2x to illuminate a take 24x12x16 inches. Even on very shallow tanks it’s hard to believe you’ll be able to grow anything but the lowest of light plants.
Another design issue I instantly hated was how few “High output” LED’s there actually are in the fixture. The spacing is so large if you have a high aqauscape you’re actually able to see every color as a separate, unblended LED that doesn’t look well at all. Also, It’s moonlight setting is more violet and “OFF” looking than any other light I’ve seen, but not more off than the 10K lights themselves. With so many better made lights it’s pointless to waste your hard earned money unless you’re planning a fish only display and a huge tank. This is a cheap light. It looks cheap, it acts cheap with strange flickering and you’re better off spending an extra $20-$30 for a light that you won’t have to upgrade to in a year anyways.
** BeamsWork DA
This is a light I knew I wouldn’t like. Just like with the FSPEC model it’s white lights are 10K lights more suited for reef tanks or Cichlids (Not that you’d ever be able to keep a reef tank with it) and it has Blue Actinic lights.
GOOD It’s easily twice as powerful as the FSPEC series in terms of lumens and PAR for some reason, but don’t let that fool you into thinking you’d be growing anything but low light plants in most tanks. This light is built much better than the first BeamsWork I listed with a sleeker design and a lower profile on the tank. It’s far superior cosmetically, and the blue moonlights look okay… I guess?
BAD If you’re looking for a cheap planted tank light stay far away. It’ll grow plants - this is for sure - but in the 10K Cool Whites everything is bland and colorless in my opinion. It honestly has all the BAD I listed for it’s FSPEC counterpart except it only comes with white and blue lights, so you don’t have spotlights of green and red at the surface of your tanks.
For the price, once again there are better alternatives.
AND THE UGLY CONCLUSION:
At this point I was going to test a few other lights, namely Mingdak, the EVO line and possibly a few others when I realized two things: BeamsWork makes a lot of the lights I considered asking to borrow from people like EVO and what was the point? After seeing the performance, illumination and all things considered I was able to scroll through seller’s items and easily determine what was junk, what was okay… and what might work. This immediately sliced anything I wanted to test in half.
YES! There are success stories and people grow nice tanks with these lights, but the actual lights they are using are hard to find and just as expensive as a quality light. They almost all use the 10K lighting, have horrible LED spacing and are cheap; AE-Shops, Mingdak, Green EVO, Zeiger ECO… Expensive - all of them - when you consider you’re buying junk.
*** CFL Lighting - NOT LED obviously
Those twisting lightbulbs you see in lighting aisle at the store? Yup! These are actually pretty easy and you can run two or three above tanks, then with a decent reflector you have warm white that’s intense and pleasant.
GOOD You can light an aquarium pretty cheap with a DIY attitude and a little bit of electrical know-how. The light is pleasant, and it definitely works.
BAD There is honestly not much bad about this method, other than if you get poor reflectors your light spread can actually shine more outside the tank than down, penetrating the depth of your water. The only other bad I can consider is your plants aren't rendered by these lights in any flattering sense, but not in a bad way either.
** Finnex Stingray
I only have the clip on version, so it’s not the best of reviews. The concept is the same regardless.
GOOD Finnex isn’t the most expensive, but for the price it’s top-notch. As much as I hate the generic LED suggestions we offer I can’t disagree. They do exactly what they’re supposed to do and what’s more important for me is the 6,500K-7,000k spectrum almost all are. It makes both fish and plants look wonderful. This light is no exception, and usually on shallower tanks it’s running 30 micromul of PAR which is considered low/medium lighting.
BAD This light makes no sense to me. Truly. It’s overpriced for a low light fixture, featureless and outclassed by almost any other light Finnex makes. When I bought a clip on it was because all I’d ever known was Finnex and I got it for a good price. Having said that, I must have gotten one that was bunk because two of the white lights I just noticed were dI'm and flicker. This isn’t necessarily something that deems this light bad because I have two other Finnex lights that are remarkable and perfect almost two years later, so yeah… I got a bad one. It happens.
*** Finnex Fugeray Planted +
This light is often a go-to suggestion for high light tanks. I bought one and it’s wonderful, but again… why do they even sell the Stingray or this light anymore? It’s outclassed, outperformed save for a single viable feature only this light in the Finnex line up has as far as I know. I may be wrong?
GOOD This light has 660 nm RED LED’s. So what? That doesn’t even mean anything to most of us, and for the rest of us we just don’t care. It’s considered an optimal color VS other RED LED’s for photosynthesizing, marketed for INTENSIVE PHOTOSYNTHESIZING which in itself makes ZERO sense. I mean can anyone tell me what that means? It's listed on almost every seller's description and for the life of me it means nothing that I can figure out. Speaking very blunt, it doesn’t mean much... except this red lighting (the fixture) give a wonderful visual color to red plants that so many of us love. Not only that, but it’s a pretty good light for most people’s needs and that’s not even mentioning how modern and sleek the actual fixture looks! There’s a moonlight feature if you’re into that...
BAD Where to begin. Overpriced in my opinion. For wider tanks you’ll most likely need 2 of these to cover the whole bottom due to these LED’s having a very poor spread of 120 degrees and the actual fixture being very narrow. They could have canned the whole moonlight feature and gave this light a dimming ability and I’d probably pick it far above the next two, but it’s inability to change intensity without raising the light (which takes away from the fixture) makes it less useful in my opinion. The moonlights are cute, but ultimately a waste of what could have been a better feature.
Like I said, for someone new to plants this fixture is High Light and a lit firecracker, which is why I disprove with it being suggested generically and here’s why: You can EI dose to an extreme level where you poison your shrimp with copper and have nitrates off the chart, can inject Co2 to a level where you’re fish will perish, can even neglect vacuuming detritus for a long time with no ill effects in terms of algae in a tank that’s cycled as long as these are short term mistakes but the #1 issue is not maintaining a balance with lighting being the root of all evil. For those who have never found a balance or needed to in their experience the level of PAR the Planted + emits is only going to be a nightmare, especially if you’re a slow learner. Okay, not ALL people will experience my theoretical scenario of Algae Farming for Noobs but if you have a light that’s absolutely nuking your unbalanced tank you either want to fix it and you spend hours (then weeks) altering it here and there or you just give up. Either way, it’s wasted time and not fun when you can’t seem to do anything right to get rid of all that algae.
**** Finnex Planted + 24/7
GOOD This is a gem in my experience. Both people new to plants, and those experienced can benefit greatly from this light. Just like all the Finnex lights it looks stunning both in the water and outside of it. in comparison the LED’s have a better spread than the planted +, giving more coverage side-to-side. It’s PAR level is on par with it’s brother the Planted + with only a slight difference that will not matter. You’ll be able to grow high light plants with both. The benefit of this light and why I think it outclasses the other Finnex lights is the remote where you can preset light output and adjust color, meaning you can grow low/med/high light plants given the right tank just by adjusting it.
BAD The IR sensor is ugly. I’ve never been able to grow anything better than algae while on the 24/7 feature, making it useless to me. So yeah, their huge 24/7 selling point is nothing but junk. It lacks the Planted + TRUE 660 nm RED LEDs, but red plants still look wonderful. Almost all of it’s features are gimmicky.
This my pick for almost anyone just starting out - whether it’s a highlight 20 G Long, or a low light 20 G High. Because of it’s adjustable settings you can bring the intensity to the level you need it to be. Why is this important for people new to the planted tank? While you can have all the nutrients for a carpet in your soil, even dose via the water column you then have reduced the limiting factor for plant growth and ultimately the growth of algae to Co2 Levels and Lighting. If you buy a light that isn’t capable of dimming you must increase Co2 levels to meet the demand of the light, balance, possibly adjust nutrients. In high light this hard-to-explain balancing act is quick to topple and unbalance causing all sorts of problems with deficiency and algae. If you’re able to knowingly give a limitless supply of Co2 and Nutrients within reason then the only limiting factor is lighting. By having a light that can dI'm you’re able to always adjust the intensity to meet a level of demand where light becomes your only limiting factor, which in terms of ease is much less intensive than trying to meet two factors to the high demand of one factor.
Making lighting your only limitation is the quickest way I can teach someone else the balancing act that is the planted tank.
Furthermore, I always buy for the future. If I want a low light tank, I get a high light fixture knowing in the FUTURE I will most likely change my mind and buying ahead for that situation saves me from buying further equipment. This light meets those needs.
**** Chihiros A-Series
This is actually my top pick. I came across this light by pure accident. Being a ADA knock-off for 1/3 the price I had no idea what to expect.
GOOD This light looks better than most Finnex fixtures with it’s brushed aluminum body and Acrylic legs. The way it fits spot on. Like all ADA products it’s not meant to be “hidden” like some fixtures, or so small it simply fades from view. It’s supposed to be seen, and therefore, it’s made to look just as good by itself as it does on the tank. It comes only in 8,000k spectrum, which at first I hated in comparison to my Finnex fixture. Everything looked drab and washed out, but it’s grown on me and for green plants I like it more. Also, this light is by itself in the high light rating on my 20 G High, but because it has an attachable dimmer switch It becomes whatever level I need it to be. It’s super bright. The 60cm fixture is hands down brighter than my Finnex 24/7 (30 inches), or Planted + (24 Inch). The best part for these high light fixtures is that they WILL fit on standard tanks, although not alway an optimal fit, and most are between $30-50. I picked up two A601 (60cm) fixtures for $60! That’s crazy considering one Finnex fixture this size will run anywhere from $55-$100 and LED’s like the stingray are outclassed.
BAD It has no adjustable legs. the fixture is exactly what it says and there is no adjustment unless you modify it or purchase the expensive stainless steel legs. at 8,000k it can look drab to some and definitely does not render plants that aren’t naturally green in a flattering way, nor does it have any colored LED’s. They are 8,000k white LED’s that are colder looking than a 7,000K Planted + 24/7. It’s also tricky to order because you need to find a seller that has both US PLUG-IN option and 110v for power.
EDIT: I somehow managed to forget a very important BAD aspect of the Chihiros A-Series and only remembered it when I was cleaning my tank and bumped the light fixture. It made me jump, surprising me at how HOT these get. The only reason I can offer is the LEDs are attached to a heatsink that is insufficient. The seller claims that the light will not get hot enough during a 12 hr photo period to damage or even burn out the LEDs. I have yet to read anywhere that this became an issue and to further that point the ADA fixture this is cloned from also runs very warm. It's not like it burns you or appears to be any sort of risk of burning down your aquarium it's just hotter than you'd expect.
Hope you all enjoyed the review/rant
