K guys so here are some numbers from my T5HO TEK (bulbs are 10,000k; fiji purple; 10,000k; fiji purple; 10,000k; reef blue. all bulbs are aqua science. I measured first at my sand bed, than top of the rocks (which is mid tank) than surface reading. Measure used was a milwaukee smark luxmeter sm700 on the 20000/50000 x 100lux setting. Tank is 16" deep and the light is 3-4 inches away from the surface.













Also for fun, my 20" NEP using stock current bulbs (3 10,000k; 3 aticnic's). One reading at surface and the other is the sand bed.
