i have been reading up about LED
lighting. i am just curious how far out of the box people have been looking to find cost effective solutions to this. i know there is Taotronics, rapid led
, the chinese units as well as many others. but i was looking to spend about 50 bucks. wanted to provide about 40 watts of led
over a 15 gallon tank. im curious as to how much kelvin comes into play. what colours should u be looking for. what specific numbers should i be looking for in the description of the led
. when it comes to tvs u look at contrast ratios and refresh rates and stuff. so i assume leds have certain numbers u want to see. here are a few options i have found
this is a small self contained unit. puts out 20 watts. description states its waterproof and is "cool white"
here is a link to it

Shell Material: High Strength Aluminum

there is also another identicle unit but with selectable colours between red/blue/green/purple/white etc
any opinions are welcome. the unit is only $25. the colour changable one is $45.
