Hoping to get another life out of a spendy tri-pod light by replacing the COB LED. I’ve tried 2 attempts at cross-referencing the part number with no luck.

Original COB is a Toplite TE-R23-JU-A1

Fixture is a DeWalt DCL079, 20V single lamp light with a low and high setting. Confirmed power at the head, but no light.

Anyone have ideas on a replacement COB?

Thank you.

Here is a picture of the old LED…

Greetings,

Searching that P/N suggests it’s a 28mm square LED with roughly a 35V forward voltage; if one’s seeing an open-circuit voltage at the head somewhat above this latter figure, that’d suggest this information might be reasonably correct.

[These](https://www.digikey.com/short/zqd8d0qp) are the items on hand which would appear to land in that ballpark. Check dimensions, and choose your preferred tradeoff of efficacy, CRI, color temp, etc.

Don’t omit a smear of [thermal grease](https://www.digikey.com/short/tfh28rqm) during assembly, lest the replacement also take early retirement…
