    Ordered 1 before and was very impressed and ordered more this time. Is as good as any fluorescent BLB bulb I've ever had and 3 in series used with a 21-38V 900mA current limited LED Driver makes a very nice UV source for a whole room. A 30W UV LED could also be used of course, but much easier to find a suitable heat sink for these smaller 10W LEDs.

    Ordered 3 and plan to buy more. Very Good UV source but need to add a heatsink of course if run at a full 10W.

    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 !
