do you people think it's worth it? Just do the math
it would take 2 1/2 - 3 years to pay off as oppose to using regular T5 bulbs. (one 24" T5 is $20, the E5 is $50).
this is just my opinion.
I think we need to think a little before buying these E5. will you be using T5 for the next 2+ yrs or not .
if you don't plan on using T5 light for more than 2-3 years then I would just stick with the regular T5 bulb.
For my purposes yes. I have ran t5's for 6 yrs, mh's for 2yrs and led for 5+ yrs. I switched back to t5 about a year ago and will not likely change again. My issue is I love the blue led pop for lps and softies, but hate having led's on the side of my ati fixture. So adding two blue pop's in dusk to dawn was a no brainer. Much cleaner look........but agreed it completely defeats the purpose to replace all your t5's.
