    Great UV Led, I use it to cure UV glue. First try it without heatsink, but the Led got hot fast. For full power a heatsink is a must.

    Very powerfull UV led cob technology! Used for a small post uv resin curing with 3 of them for a total of 30W They need a big dissipator if powered at full power.

    I used 4 wavelenght uv led (390-395-400-405 nm) and 1 visible for making an experimental portable flash light. It works fine, just I didn't note differences on wavelenght, it seems to me that 390 has the same behavour of 405. It could be a broad band emission.

    A voir sur la durée, mais les 1ers essais de branchement montre que ça chauffe à près de 60 degrés C en 5 mn, prévoir un radiateur et ventilo au risque de la faire mourir prématurément de chaud. Contrairement à ce qui est dit dans les Questions/réponses, il faut TOUJOURS mettre une résistance en série d'une led, et si vous voulez en brancher plusieurs en parallèle : bon courage pour ne rien griller car il faut 1 ampère par led !
