for the tent itself it is an 96"x48x78 600d reflective mylar tent link to it
here
the light is a 1200 watt full spectrum
MEIZHI LED
I have not done any light tests to determine the exact amount of light the whole area gets with any reliable equipment but using a lux measurement app i got around 49,000 lux a foot under the light (i don't hold that measurement to be accurate however).
the coverage seems to be pretty good however, I have a hot pepper plant off to the side of the light and it still is getting lots of flowers on it.
as for the impact on electricity I do not really know yet since it is a really new setup. I run the lights on a timer that turns on at 7 AM and turns off at 8 PM giving the plants at least 13 hours of light and they don't seem to mind the extra light one bit

I agree with you on that getting LED fixtures cost a bit but I think they can be a pretty great long term investment given that it suits the need of the situation. Now the LED I got is more than likely overkill for a grow tent this size but the deal on the light was great at the time
