Do not get any light from vivosun.
You can't go wrong with 2 315w LECs (CMH) with the 3100k phillips bulbs. Keep in mind you will have to replace bulbs after so many cycles, they are around $70 bucks. Very good bang for your buck fixture currently, pretty sure I paid almost $500 for my sunsystem 315 in 2016 and they have gone way down! I would run 2 315 watt LECs with the LED fixture of your choice in the middle for the 8x4. Then you would veg with the dimmable LED.

I love that anytime a "which light should I buy" thread pops up it gets 6-7 pages of replies on the first day

Will give that one to HLG...at least their product name is the true wattage.

This thread sure turned into the Lighting Matrix. Whatever you decide to get for your first grow. Most companies have a good return policy so if you don’t like what you initially get or it doesn’t work how you want it too. You could always send it back and try the next recommendation. Good luck

That sounds like a good idea. just mix it up so i have led and CMH. might just do that since no one is for sure set on one and i am getting confused on what to get lmao.

Nah, same efficacy, but better spectrum.

Research this stuff yourself. You are not going to end up with the best light listening to people here.

Not true. CMH is more PAR efficient and produces more usable light watt for watt than its HPS/MH counterparts.

Philips cmh 315 agro = 600 umol/s = 1.9 umol/j
Phlips master greenpower 400w hps = 750 umol/s = 1.875 umol/j

I am getting 4 of those CMH or i am getting 2 of the CMH and 240Watt kingbrite. how does that sound? would the 2 CMH and 240watt Kingbrite do it good?

That would be a great mix. Personally I would do 1 630w CMH in the middle of 2 240w LEDs. The 630w CMH covers a 4x4 and the 240w LEDs each cover a 2x4 so it would be perfect coverage.

imo, im happier with my off-brand purchase (hy-grow lighting solutions) than i am with my SF-4000 or my Mars TS-3000. Dollar for dollar? These lights use the new 301H quantum boards, they have the same mean-well drivers.... and they cost less. still having a warranty. check these out by going to ebay & putting in item # 224099537146 into the search bar. i think the $219 (w $18 shipping) is the very best deal on quantum boards right now. that’s under $1 per watt. SF will cost around $1.33, and they (as well as my Mars) uses the older Samsung LM301b chip. Hygrow sells several versions, and i think the 250w is the best, as u can get several & space them out, getting better coverage. Your 4x8 will need about 4
