Gathering the materials together for my next build a reef jar with a volume of about 2g. I was pretty stuck on lighting with it all being so small and made out of plastic. Picked up a desktop lamp and 12w LED bulb which is 6500k spectrum and 1500 lumens. Its the equivalent to a 100w normal bulb apparently. I'm just a little concerned about the 6500k spectrum? Will this lighting grow coral?
