Just found them.They are the kingbrite 60w fixtures. Looks like someone has bought in bulk from Jerry & is looking to make a few quid on them. Cost from kingbrite around $60 plus shipping & import tax. eBay £110

When they do ask them to mark them as samples at a lower rate on the invoice. Since you will pay 20% import duty. The lower they mark the price on the invoice the less you will have to pay in tax.

So I want to make a 2 COB citizen system,


Hello again mate, I am New to the DIY led game and want to learn by building a kit myself, I have the basics of electrical work and I watched a few videos and it looks as easy as wiring a plug, if you don't mind can you please send me a list of components needed for a 100w citizen COB system so I can source myself and have a go? I'd be really grateful mate, I totally understand if you don't thou it's a bit cheeky and lazy but I don't know how to match LED with drivers and don't want to get it wrong, thanks in advance, I asked someone on eBay to build me 1 but he quoted me way way too much

No problem atall.

I can give you a parts list but it will cost a lot as its hard to buy single cobs/heatsinks in the uk for a good price (yet ), i buy bulk.

2x Citizenclu048-1212 (ebayuk)
2x 120mm pin heatsink (tapped for clu04
2x bjb clu048 holders
thermal paste
-----
ip67 3 core connector
3 core wire +plug
hlg-120h-c1400
1/2" aluminium profile
18awg (1mm) 300v wire

I charge £150 for the above but no stock .You should be able to buy the parts (not from me) for around that.

You could buy the bits off ebay or search mouser/tme/digikey etc.

would it be beneficial to use lenses or reflector's

StonerCol said:

There is an argument to use neither tbh.....lenses can focus too much light in one area and harm a plant. Reflectors absorb many photons, heat up and add to your room temp. In a small area with mylar on the walls then it might be better to use neither.

Cheers mate,is it a matter of unscrewing the reflector's if they come with them already on? I'm buying the plug and play type ones just for supplement lighting and to achieve 40w per sq ft , I have just stumbled upon quantum board's which would be much better for my application but shipping from USA is a nightmare lol

Yeah I think you can unscrew them. I'm getting my cobs made without and have never bought plug and play ones so I can't be certain.
