Found these lights at a scrap yard

[Lurker500]

Hi guys,

I found these lights at a scrap yard and bought all 7 i could find for £20.

They all work. Very well made. Slight damage to heatsinks due to being mistreated. Plastic lenses are a bit scratched up.

Luceco LHB200W-01
Mean Well HLG240H 48A
200W 4000k

Can these be used effectively?

I'm interested in your thoughts and opinions. Thanks.

200w is a little low. You could probably use them to supplement. They also might put out quite a bit of heat..

 

[rkymtnman]

200 w per fixture is hardly low IMO. 1400w for that price is a steal. maybe add some reds for flowering. great for veg

Luckily they are 4000k. That is the coolest I would flower with. Since these are the A version, I would get a wattmeter and turn them down to about 100w each(maybe 150w) and run about 4 per square meter. This will improve there efficacy.

I currently have 2x600w viparspectra and I'm not too impressed.

Using a grow area of 120x120x200

@Lurker500 If you are afraid of a little wiring you could also wire 2 heat sinks to one driver. Then you have a few high quality drivers to play with.

Great advice atm, thanks.
I'm on a huge learning curve with LEDs.

hells yeah. everything looks solid, upgrade the cob chips and you'll have a state of the art rig for next to nothing

Which Cob do you recommend? Thanks

He'll of a find. I'm quite jealous of those heatsinks

on voltage id rec the luminus cxm22.

do those heatsinks have multiple holes for mounting chips? or if there are only 2 holes are the holes for the cobs that are there 35mm apart?

35mm is common spacing for many cob holders

4 small screws mounting cob. I'll drill new holes in the aluminium plate if needed.

cxm22, 3 or 4 per driver

When I saw them I thought "omg, this can't be what I think they are??" I wanted the heatsinks, the lights working was a bonus

 

[CobKits]

actually i didnt realize those were so massive and one cob per driver. you want citi 1825 or luminus cxm32

citis will top out at about 160-170W and the luminus would do 210-225W each (assuming those drivers do the usual 54V max)

they may have had them turned down depending on spec of the heatsink

 

[Lurker500]

The heat sinks measure 9x9 inches.
They get warm but not too hot.
Thanks for the advice too.
From manufacturer specs I think is 48v max?
And they do a 54v version too.

Great find .... a little COB upgrade as stated and you are golden.

You can go with reflectors instead of lenses.

 

[Lurker500]

Ok so if I were to get a high power COB with a preference to flowering, suited to the above driver, which would it be?
Thanks.

And alternatively what driver/cob combo to match these heatsinks.
