I have used the Bright stick on a 10. Although it is cheap WPG
, it is not cheap Lumens per watts. The 33 W Bright stick puts out something like 1/3 or 1/2 of the light of a good 32W T8.
It is a good easy way to get some light over your plants/tank (stick on, no wiring needed), and it did lasts a long time. However for amount of light output per dollars, a T8 shop light works out best (fixture cost, without even factoring in saving in electricity.)
