    . Heavens. I've read everything I can on lights. My mind has a tendency to shut down when they're too many numbers in front of me. However I do have 2 of the the Home Depot plant/aquarium light bulbs 15watts each. But I still cant understand it. I know I have lowlight I just want to know if I get LED would that be any brighter? I have a 40gal 36" long 21" high planted tank.

    yeah thats low light. I've gotten one of those bulbs before, i switched it out because it isn't really the best for aquarium plants. Depending on the lumens, which is the actual light output, is what will tell you which setup gives you more light.

    I say CFL bulbs are good for plants. A rating of 5000k to 7000k is great for plants

    what's a CFL?
  5. AquaticBrandonWell Known MemberMember

    Compact Fluorescent Light
    You can find them at Walmart or Home Depot

    The lighting you need is dependent on what plants you have/want to have. Here's a good article on PAR values (which are the most accurate practical way of judging how much light reaches your plants).


    CFL lights are good for small tanks, but generally won't work on a tank your size.

    I read Hoppie's thing on Par and that's what got me dizzy. I just want to know if LED is brighter than plant/aquarium lights their Lumens is 470 which means nothing but that's the only information given on the box.

    Are my Plant/Aquarium bulbs CFLs? They say Lumens 470 but that's all they say. They're flourescent bulbs in a shop light.

    Brightness depends entirely on the light... I can't tell you LEDs are brighter than flourescents. Some are, some aren't. If you link us to the actual light you have, we might be able to help.

    Basically to grow plants in an aquarium, you want daylight spectrum bulbs (5500 kelvins to 7500 kelvins) of an appropriate size for your tank.

    Canadian Football League, of course, where Warren Moon spent 9 seasons, and is now in both Hall of Fames, which are well lighted, just in order address your question--sorry, will get about to that if I happen to know:)-rick

    I agree with junebug. We can't exactly tell you if LEDs are brighter because specifically some LEDs are brighter and some aren't. A picture of the bulb you have might help us be more specific.

    My Fluval LED lights are much brighter than the lighting that came with my Fluval Edge 5 gal. Sometimes I wonder if the lights hurt my betta's eyes. And I never had a problem with algae until I installed this type LED on the Edge 5. Don't know whether it's due to the LED or not? Am considering putting the LED on the 16 gal bowfront that is other construction. My lighting is on typically9-10 hours/day. Any comments/advice/replies would be appreciated. And I hope I just didn't hi jack a thread. If I did, please let me know, and help me place it in the proper category. Thanks.:;balloons
