Ive been looking a big ne brand lights myself but havent been kn the budget. I grabbed a 200w Bestva board and pulled 10 oz on a test run in my 2 x 4 last year. Pics in link below. Bought another and ran 2 in my 4x4 with good results, well over a lb. Running one now in a 24 x 30 but turned down. Pretty cheap @ $150 each and on my 4th/5th run with em.
I run in my garage in the winter and ac cooled room in the summer, the attached driver helps with some heat.
