Helix Compact Fluorescent

[dingweding]

i bought 2 helix compact fluorescent bulbs, 15w each. It said it equals to normal 75w bulb. So when i calculate my lighting, should i think it as 75w or just 15w? Many thanks

I take it those are bulbs for houses and not aquariums?

yes, but the one i bought is daylight. i specially choose it, i want to use it on my table lamp for my nano tank.

It's 15w. Although probably less, since the shape would cause some restrike and most table lamps do not have a proper reflector.

All I can say is I tried the cheap light route and got nowhere. The lighting over a tank drives the whole process of plant growth and is consequently the most important aspect of a planted tank IMHO. There is no point having the best substrate, plants, CO2 kit if the lighting is crap.

However if this is for a nano, the sheer amount of light might be enough to get the plats to grow, just don't be surprised if they don't. Moody used a halogen desk lap on his tropica cube and the results speak for themselves, so it is possible.
