Homedepot compact fluorescent Spiral bulb 42w and 19w

[ctxmonitor]

Hey guys..

I just been to homedepot and got two type of light. They both are made from Commerical Eletric. The more powerful one is a 42w Warm white light as it label on the box and another 19w Daylight bulb. Since this my first time attempting installing new light to my 20g aquarium, i am clueless as how this may work. I planning to put the 42w up on top of the tank sideway, since i was thinking of reusing the old hood.. This is the warm white light, and not the Daylight as prefer by many hobbyist.

I just want to know if anyone else have use these bulbs or any spiral bulbs on their tanks before? Is it good or bad..

Orion is using a spiral CF hood, and im also in the process of making one. as far as i know it works well, the light is a different colors from store bought aquarium lights but other then that... i dont use a 19w or a 42w but i imagine theyd function similar.

Thanks 420Loach.. The 42w warm white light is a little to reddish too me.. I like the cool or blue light fluoresent which is often seem on the tubes. But as many, the intensity is more imporant.
