I was at HD and saw some LED light bulbs, which I think would be great for my fuge. I think!!! Well there were two that caught my eye. Both are 60w Cree bulbs, difference was one was daylight (5000k), and the other was a warm white (2700k). Would any of these suffice my fuge, if so which would you recommend? If not what are you using to grow chaeto, caulerpa?
