Okay 6700k bulb thats what I wanted to know granted more light they would grow more but the spectrum (couldnt think of word at time) was my question. Thanks

Have you considered simply using 1 or 2 dome lights cheap types sold at home depot/lowes with energy saver floursecent bulbs they have 23 watt types that equal 60 watts in light or think 12 watt types that equal 40 watts.

They carry the 6700 k bulbs infact even cheaper GE plant bulbs sold there are 6700k . Granted you can just add another bulb or dual light strip .

Thanks again going to get the spectrum as setting up golden mantella tank but ofcourse need to plant it prior to getting them
