My girlfriend has two of these bulbs for her 10g. Hers are 10W each (Similar to a 40W incandescent each). Her plants are growing rather well so far. She currently has Anacharis, Water Sprite, and Moneywort all growing in the tank. The plants have been in for a week or two and there are plenty of roots growing. I believe her bulbs are made by GE and are 6500K, which is a good Kelvin number for plants.
Are those spriral energy saver power compact lights any good for planted aquarium?

Is that a 40W incandescent equivalent you are talking about that only actually draws 10W, or is it actually a 40W spiral bulb? I noticed you had a 36g tank. Thus, you should figure out how many WPG you want. WPG is a rule of thumb based on fluorescent bulbs, so 40W for incandescent will be different.
these are the ones i have over my tank. until i upgrade my lighting i have a 20 strip and 4 spiral 10 over my 25 gallon. the ratin is 65k and is very white. my plants all seem to be doin well, especially my dwarf sag which is sendin runners all over the place. i was thinkin bout addin extra light sockets to a 10 hood to add 4 of these bulbs to one hood.
Yes, they work good, atleast for me. I hace a 20 gallon high (16 tall) with two 25 watt, 5100k bulbs. My plants grow good, except the only bad part is that my light is more in middle in tank, and less on sides, because my bulbs are more in middle. Works well overall, and is cheap!
you want globes in the 6000 to 7000 kelvin range so the warm white and cool white are to low, you want the cool blue globes whice give off about 7000kelvin
when talking about the lights we only talk about actually power drawn. most of the time it says in big letters 150w and in small letter 27w used.
The other day I read this thread. I went out and bought two 10w bulbs and screwed them into the typical hood top that you get with a 10g. These things are good. They cast shadows. I was going to use this as your basic low light tank but I think I could move that up a notch easily.
i saw someone mention lights of america bulbs and found some at walmart, they're pretty nice screw ins. i think i like em better then the spiral bulbs, but will see how things wr out. but if ur goin for space savers the spirals are best
