Look around man. It is cobs and QBs everywhere. I don't think many will recommend either of the leds you listed over cobs or QBs.

Skip that step and go for Cobs or Quantum boards..

I vote Meizhi 1200, because I have one meizhi 900w, still works well, cheap and durable
diy need too much time!and I ordered my meizhi 900w on ebay, it's cheaper than amazon.

A quantum board build takes maybe half an hour if you've never done it, and isn't that horrible purple color. Oof.I vote Meizhi 1200, because I have one meizhi 900w, still works well, cheap and durable

Can't compare on price, know nothing about Meizhi.

Bro, you got the point, when my old friend recommend meizhi light to me, I also told him: do not compare on price, I don't know meizhi light and never use it. But I still tried meizhi light because it's very cheap, then, it surprised me, like it

a lot of lights grow great you can use T12 tubes and raise a crop that doesnt make it efficient.
it seems like the recent trend by unscrupulous chinese purple pushers are youtubes with plants under them - "look! it grows weed!" well no shit......
its sad that their customers understand nothing about efficiency and will inevitably try to replace an HPS with half the wattage of an overhyped overpriced inefficient LED to disastrous results, setting the LED movement back a few more years

They're still efficient, just not what they say on the box, 300w usually means 135w
450 closer to 200 and so on
They're capable of 1 gram per watt used so can just about keep up with hps, but cobs and QB can get 2 gpw !

Wow, we have 2018 and there are still some noobs falling on for the blurple swindlers!
Forget them,mate, or use it as a party light, LOL, they have nowhere near a perfect grow spectrum nor are they efficient.(maybe 30-35%)
F-Strip or Quantumboard based builds are easy to realize because of its poke-in connectors.(up to 60% efficient)
You only need a frame to mount the strips on and a siutable driver and of course some awg20 single core wire.
I strongly recommend you to visit www.ledgardener.com, the guys there collected a lot of useful info's about strips, incl. how-to's and wiring examples.

I know all about the spectrums and how much better Samsung diodes are as well as cobs, I bought the vipar and meizhi before I done the proper research lol, but ive fumbled through my first couple harvests with them and they do grow!
Obviously you can grow with any light, but I mean ifnit can get 1 gram per watt used they can't be complete garbage, basically hps efficiency without the heat.
If I could turn back time I would be sitting with a double QB120s but for now the blurples are doing me proud for £50 lol

But higher upfront costs pay for them self very quick. Remember the difference between a 30% and a 60% efficient light is twice as much possible yield. So you play the higher cost in again after 1 or 2 grows and from then on you make double profit with the same power consumption.
I would rather pay 300 bucks for an 250w EB-Series, gen2. unit as 100 for such scrap.
But everyone has its own opinion...

What happens when you don't have more than 50.. non negotiable

Sorry for the delay, mate, fall asleep yesterday. Completed the housing for a new light and have had a hard time trying to get all the cables, drivers and Sonoffs into the housing.
Back to topic!
I would use the Vipar(or any other blurple) just one or two times to save the money I need and then I would rebuild it with COB's or make a whole new one using efficient strips.
Believe me, most of us started their LED expirience with a blurple unit(bought or selfmade). My first lights were two 300w Mars reflector unit(the ugly green ones without lenses, 2014). I tried to finish an outdoor lady indoors who needed 3 more weeks, but with moderate success.
They ran only the 3 weeks, then I sold them on e3ay and built my first Vero29gen5 unit.

Hehe, I wish I had more time. Hopefully I get it running within the next week. Still waiting for six XP-E's in 730nm to integrate an IR-Trigger between the CRI90 COB's.
Driver housing is ready so far, I need only to add the LED's and both Sonoffs must be paired to my android tablet. Only the XP-E are still missing...
The following will be added in the next few days:
The HLG-240H-C1050B gets 20x 2ft. F-strips in 3000°k in 10S2P (Sonoff Dual, channel 1)
The HLG-120H-C500B gets 8x V18c COB's in 3000°k/CRI90 in series (also on channel 1)
The 120° reflector gets an 39w Arcadia D3, 12%/30%UV-B/A(Sonoff Dual, channel 2)
A small 5w driver will be used for the six XP-E/730nm(Sonoff Basic)
A small 12v/0,5A driver for AV-meters
Hopefully the Sonoffs do not cause any problems. Have read some reports where slower growth was mentioned.
I hope I do not have to take them out again.
The pictures below show the first attempt to squeeze everything into the case, but it did not fit so I had to do everything again. Now everything fits, thank God.

The pinkish strips are not tested further, but I plan to mix them with 2ft. EBgen.2 strips (8+ and use them for my small 3ft² veg area. But most EBgen2 strips are not available currently. Next delivery comes 03/30..

Hehe, yeah, probably neither Samsung nor Bridgelux has had that high demand on the screen. Hope their production is running at full speed, if the new ones really do not arrive before 03/30 they are sold out within hours, lol!
