Hello sg.fock,

Welcome to the DigiKey TechForum.

We do not have a direct cross to this LED COB.

The closest alternate is part number [976-BXRV-TR-1840G-10A0-A-25-ND](https://www.digikey.com/en/products/detail/bridgelux/BXRV-TR-1840G-10A0-A-25/12317918?s=N4IgTCBcDaIJwHYBsBaAQgDQEoDUUBUsUBGADgBYAGAcRMoEFKV6UwBWFAOQBEQBdAL5A).

This is 18V typical instead of 20.7V, and the size is smaller at 15.9mm X 15.9mm, instead of the original size of 22.8mm X 25.8mm.

Please check the [Datatsheet](https://www.bridgelux.com/sites/default/files/resource_media/Bridgelux%20DS350%20Vesta%20Series%20Tunable%20White%209mm%20Gen%202%20Array%2020200123%20Rev%20C.pdf) to verify compatibility to your application.

If we had a range of what you can use, for the size, current, voltage, brightness,… we can see if we have other options to offer.
