I put two of these: http://www.1000bulbs.com/product.php?product=9135
in my 2'x4'x7' cabinet, and believe it or not, they work great ... one possible negative, depending on how you're arranged, it is also a 1600 lumen, warm spectrum light, so when the lights go off, so would the ionizer ... P.S. ... NO negative effect on my girls, whatsoever ... :thumbsup:
