yes 18ga but make sure it's solid wire for the cob holders and I use a 1/8" drill bit with #8x1/2" self tapping screws and as for one stop place to go that question I can't answer:cry:

Can I ask you a couple questions? Why solid core 18AWG? I was under the impression you can use stranded wire as long as you tin the tips to insert in the holders and 20AWG is capable of 7.5A enclosed 11A free air (I believe this was the figures last time I looked) So is it necessary to use 18AWG. I can understand if your driver is remote mounted and you want minimal voltage drop across a longer wire but not much v drop in short runs. Just trying to understand what drives people to decide on certain parts of there systems.

I see ideal holders can accept up to 18AWG so why not use the max wire size for least amount of voltage drop. The holders I have BJB holders call for 0.5mm2 wire size max which happens to be 20AWG. I am thinking of using 20AWG solid core to make connections and pigtail off to 18AWG for the rest.

I believe it is because of the Ideal holders, canadian......thru dumb luck I found my 20 awg multi strand was popping out of the holder, very easily! Then the talk was using a larger gauge single strand to prevent this...and as you have way more experience in the general electronics world....Tinning will probably work the same way and would have saved me time instead of switching wire sizes out....:) :joint:

That makes more sense to me now. Yes if you do not tin the wires then they can easily pull out of a friction fit type connection but tinning them gets basically the same end result as using solid core wiring.

I thought ideal's went up to 24? 20 at least......

What bjb holders are using? The 3070/3590's?

on a somewhat related note.........
I just picked some up BJB solderless holders for mono diodes [the FR XP-e's] and they are slick, to say the least!

The bjb's seem to have the cleanest/simplest look from my recollection....[correct me if I am wrong :peace: ]

Yes ideal holders 18-24AWG Solid & Tin bonded or 18-22AWG Stranded. I have the BJB///OEM Line 47.319.2151
I agree they do have a clean look to them. I never really noticed until now but realized there rated at 3A / 60 VDC which may be a problem since I am running three CXB3070 in Series which will be up around the 108V mark oops lol

Yep saw go green too. I think it's awesome! At least there are products getting out that's better than the horde of crap that's available.

For E.U growers...use 1.5mm solid wire to the holders it is a good choice,IMO.if you do not have soldering iron.

Sorry to jump the thread. what would the best drivers be to run 4 x cxa 3590 3000k CD Bin. 36v

The seller said this:
I can order in the CXA3590 arrays for you for around £65 each. These are the top-binned BD 3000K types, which will provide 10,000 lumens at 2400mA and 85C. The optimum driver will run these at 2.5A, so around 100W per array.

He also said about £60 a driver per cob? He would not say which driver.

Surely there must be a driver to run all 4 at once or is it better to run as single driver per cob?

Any help is grateful,

Smokehog

He want to take your money thats it!!!
cxB 3590 3500k 36V CD (top bin) X4 + 4x holder in kingbrite is 215 $ with shipping (2 weeks)
And for the driver a hlg-185h-c1400b would be great for them 4 70 in tme (if you are in EU)
And a 1000x165x35mm heatsink will be nice for those.
Have a great day ★

Hi @littlejacob, thanks for the input i thought he was trying to make money on me.
After speaking to @robincnn he has given me a few tips as well.

Here is what i am after..
What i have read at 1.4 amps 36v the cxb 3590 gives out 55 watts output.

My plan of action is to buy:
8 x cxb3590, 8 x cob holders, 8 x lens
2 x HLG 185H-C1400_A) with internal potentiometer, each one to run 4 cobs at 55w each

Think it comes to £357 from Jerry at kingbrite

I still need to get a heatsink big enough to take the cobs and some fans.
@littlejacob where do you get the 1000x165x35 heatsink from, cant find one that size in the UK.

I ended up choosing the HLG-120H-C1400A (To run 3 CXB3070's) for ease of adjustment without any external components but if I were to rethink my purchase I would go with the B version and add the external potentiometer (Very simple) you get 10-100% dimming with this VS 50-100% with the internal adjustment.

Build some bro. I bet if you made these and sold them for a reasonable markup you'd do great!!

Has you can see in my avatar I already have @BM9AGS but between make a light for me and start production there is a world...and a lot of $$$!
@smokehog I bought it on tme they also have hlg and wago wire...etc.the shipping cost are 7.50 € for what ever you take and price are low even with 20% vat.
Have a great day ★

Hi @littlejacob I have searched tme for the heatsink and cant find it so will email as i need 2, 4 cobs each heatsink.

Do you use a certain wago wire and male/female connectors?

I ask so when i order a few items its easier, as its quite cheap on there, thanks for the heads up.

Hello All. Just a simple question for CXB3590 DIY. I need to cover 10х4. How much cobs do i need for this area.
Active cooling, efficiency is not an issue while budget is.
Sorry for my English, not too much practice.
