Appreciate the help.

I thought I did follow the diagram with the indent but must have rotated it last minute

Cree also uses an indent in the thermal pad often, facing to the anode.

In the case of these Osram emitters, their thermal pad indent faces to the cathode.

This is the reason of your problem, I'd say. I've reflown many types and brands of emitters, and this is what happens with presumptions.

BurningPlayd0h, according to my wisdom a bigger footprint equals lower thermal resistance; or it should. 


Kaidomain has both 3030 and 4040 DTP boards for sale, check here:

Lol you are absolutely correct!

Just thought I’d share in case anyone wants some Red or Green from Convoy since it’s not listed on the store

I hope, if he is going to stock the CULPM1.TG (“Boost HX”), that he will also start stocking 4040-footprint centering rings. Would be awesome for my Luxeon V emitters…

That is something new Smile

I am not diving and I think you are very brave. Hope that some manufacturers will have zoom underwater light cause it would be far better than reflector based lights for diving. On video when you have to inspect something up close on 1-2meters from your diving mask beam of reflector light is just to intense. Wide flood mode of zoomie light would be perfect for such situations…

Zooming in a waterproof dive light would be… difficult at best.

Having a removable diffuser cap tethered to the light is a far simpler solution:

Most likely if you see those distinct traces for pos and neg on top and its copper.

To verify take multimeter and check continuity between middle thermal pad and bottom of PCB

From Shenzhen silver ingot Technology Co., Ltd.? Looks like it, the island around the thermal pad just encloses it give or take. When not DTP its surface is a lot larger, to better spread heat.

Yes, that’s the store. I thought they weren’t since I asked if the boards were dtp and they had no idea what dtp was, they said just copper.

For measuring continuity I’ve never done it before. When taking the reading it shows around 1.1-0.8 and slowly drops to zero, sometimes 0.6. Why doesn’t it show a constant reading? Probably should just watch a YouTube vid

Continuity is just the beep setting when you put the probes together. Doesn’t matter voltage or anything else. If it beeps between those points its dtp

Excellent, then it’s dtp. Thank you. Very helpful bit of info

Well, because the reading isn't constant. You are wiggling the multimeter probes, and namely moving the contact plugs and all of that. So, the resistance along the probes changes.

This remembered me of another time when I did research chemical drugs from time to time, and I always had a milligram precision balance at home. I found them faulty. Faulty because commercial balances tend to 0 when they are close to 0, which in my opinion is not very right. But alas! Device flaws like that are caused by a combination of product designer and customer ignorance, although maybe I am just asking too much from an inexpensive device. Should get another sometime, they're useful and now there are quite nice models.

Buy only the best DTP’s for your lights. Sources: IO store , greatest choice of them has the MTN , & LED4POWER when he opens a store again.

Thank you, but think I’ll stick to Convoy from now on. I didn’t realize Simon had most variants when I grabbed these, they came with the red version.

I did plan on buying from L4P but now that Convoy is stocking them I’ll probably leave it. I could end up grabbing his CC driver though

Until 4040 pads comes out, can we use a 5050 instead?

Convoy has ordered the 2mm² boost so I’m assuming he’ll sort that

And why are the boards from Hank, MTN or whatever the best? A higher price does not make something better. Price is a trait whose value grows in an inversely proportional way. This is not meant to say that paying more for something is necessarily bad, but it needs to have a good reason, a reason of service to one and all.

I am pretty sure that any properly designed and decent quality DTP board will perform within error marging of the above. Kaidomain sells great boards (3030 and 4040 MCPCBs available), for example. And if you don't need a rare size or something fancy, there are even cheaper options and many of these could serve you (some board models are not DTP or lack thermoelectric separation -as they call it-, but it can be easily discerned if you know what to look for -and they are cheap anyway-).

So what is the best whatever? One whose value and quality to cost ratio excels. Any money you save can then be used to help you, those around you, and etc.

Well you can buy well known, established and working product, and you can buy opposite. You can buy Mercedes and you can buy Yugo and sure they will both drive you to destination.

KD boards seems like a copy of noctigon V1 boards and that is good cause they should work… But question for you. Why buy from kaidomain copy of noctigon board while I can buy same original noctigon board from IO store for less money than KD boards (when I take larger quantities)?

In my experience, the performance difference between the various available boards, as long as the thermal pad is DTP, is not measurable. There are some quality differences in how brittle the solder mask is and how well the traces are attached to the boards, but I found that only relevant when a board is used several times or is severely abused by overheating. Also sometimes the underside is not flat enough to my taste or it has a sharp edge that sticks out, but I always sand it anyway on a flat surface so that is a minimal issue.

Is there any tests to show how well the Osram green 2mm2 performs? I purchased 2pcs but unsure how hard I can push them.

Awesome!

is there any side by side review for the W1 and W1.1 ?

Will there be any gain in swapping the LED’s or do you need to drive it harder?

No, but it is likely the same led underneath the phosfor as the white 2mm2 version, so I bet you can use that test for current/voltage/output behaviour.

Based on this I would expect probably ~10A for a Green 2mm. Probably an amp or two more for a 4040 footprint.

djozz, you tested the Ostar Projection PC-green 1mm² and got more than you bargained for:

 

 

The CSLNM1.TG curve isn't updated with the newer curves peaking at ≈5.7A, though.
