Ok you guys are getting confused.. take reflectors out of the question as that is not what were talking about... a proper reflector on a 150 watt DE MHwill make it seam like it puts out more light than a 400 wat SE MH.
compare aples to aples.. a PC is actualy a T4 which is nothing more than the tube size.. oh and by the way the smaller the tube size the more intence the light is for the same given wattage.
now a 96 watt PC is a 6 foot T4 folded in half so it is 3 foot long. Because of the fold there is a little light loss in the area where the tubes block each other but downwards there should be the same light out put.
I know where there are some T5's running.. maybeI will have to take my tester down there and get some hard numbers on this. the question is how do we compare them? do we do wattages or by lenght?
watages is a little un fair as it doesn't give and acurate measurment of coverage, so I am thinking by lenght.
