I had been using the Lights of America fixture for 3 months now. I had 4 (260 watts) fictures over my 135 gallon tank. Initially 2 fixtures were broken and I went to replace them. Since then 1 more fixture had to be replaced. After 3 months the light output on all 4 bulbs has significantly decreased. My plants have started growing leggy as if not getting enough light.

Today I replaced the fixtures with a new Helios fixture withh 288 watts of PC bulbs in the 6700 degree range. The tank looks like an entirely new tank. It is really bright. In addition, even though the LOA bulbs said they were 6500 degrees, I always thought they were improperly marked because they were certainly more yellow than my new ones. I would not recommend the LOA lights.
