How much do you yield off your LEDs?

How much bud do you get off a 240w Blackstar LED, or even a 500w? I am trying to get an idea so I know if its worth the $$$ to buy this LED light. I usually get a lil over 6ozs with my 250hps+100w t5

jst bump that 250 up to a 400 or 600 watt light, won't use that much more electricity and if ur getting 6oz now, you'll get a bit more with the extra power, (unless u can't keep temp regulated)

plus its way cheaper than an led unless u r getting a great deal.
