I'm not impressed with the efficiency and cost of the conversion bulbs, especially the ones that don't bypass the ballast, a big waste of power. For the cost of conversion bulbs, you can build or by something better. Look at the lumen per watt and lumen per dollar, it's not so good. I look at it this way, what part of a T5 fixture is worth reusing? I'd keep the power cord and switch, and reuse or recycle the steel.So as I was looking at old equipment and looking at options - I also was looking at veg LED options if I was going to try and veg in the same pots I flower in - so covering that larger footprint with veg focused spectrum would mean a new investment. I've got multiple T5 HO fixtures that now sit idle unused and I noticed there are some T5 HO specific LED conversion tubes (AgroLED for instance).
Are these T5 conversion bulbs worth a damn? Was thinking of a 6 or 8 bulb fixture and they were supposed to be top end ballasts (fulham) so would like to benefit from that original investment. The wide footprint is what I'm after for this - covering a 4x4 with veg spectrum/light levels being the goal.
