I run 250W Phoenix 14k lamps (DE) on my Reef and have just hit the 1-year mark on the bulbs Im currently using. Ive run them for 7hrs each day on Reef Fanatic E-ballasts. I already have new bulbs to replace them with, but am not sure if I have gotten all that Im going to get out of the current lamps.
I dont own (or have access) to a PAR meter so I would like to know if anyone out there has tested their lamps at the 1yr point with a meter and if the PAR had in fact dropped enough to justify changing them out.
I used to run the 150W versions on my old tank and occasionally went 14-16 months between bulb changes.
Thanks!
