CFL vs LED Flood vs T5HO
I bought a pair of 30w LED floods of ebay hoping to use them on my 45gal (24" tall). After receiving them, I noticed they really didn't seem very bright. I had 2x23w CFLs on my 29gal for awhile, they seemed way brighter, and a third CFL was even more so.
So, I picked up a lux meter and decided to test based on Hoppy's lux vs par meter calculation. Here is the equipment I compared:
1 x 23w CFL (6500k) in clip-on
2 x 23w CFL (6500k) in clip-ons
1 x 36" (2x39w) Aquaticlife T5HO (1 daylight, 1 freshwater bulb)
1 x 30w LED Flood
2 x 30w LED Flood
Here are the results. As you can see, the LEDs aren't getting me very far. I was really pushing for high light, but it almost seems like the CFLs would be better. OR even adding another 36" T5HO strip. Understandably, these aren't the most scientific measurements, but all were done in same ambient lighting level. Multiple lights were taken from the middle of the two, being separated by 2".
Am I missing something here, maybe I got the wrong lights, or does this seem to fit what others are seeing?
