I had a look at some lights on Alibaba that are using Samsung LM301B boards and today I received an email from one of the sellers there with the following
++++++++++++++++++++++++++++++++++++
288 FOLUX-240H-2(one driver drive 2 boards),it contains:
1.2pcs 288 board(Samsung lm301b/3000K)
2.1pc dimmable Meanwell driver HLG-240H-48B,
3.1pc black heat sink(632x195x10mm),
4.1pc dimmer switch,
5.wires,connectors,hanger,hanging wires,
6.2pcs plug and screws
If 1 set , I can give you the best price USD167.01/Set.
+++++++++++++++++++++++++++++++++++++++++++++
So basically you can get either two sets for less than $340 USD plus shipping to match HLG 550 or even 3 sets for less than $510 plus shipping to make much bigger than a 550 light. I think it is more than half price of what HLG sells them for. And they come with all wires, a dim switch and a better heatsink.
What do you think guys?
The only thing that concerns me is that HLG says they offer 3000K temperature for Flowering and General purpose and 4000K for vegging. Is 3000K going to work good for vegging?
