I ordered the chip for a Led flood light that I have for some time. The luminosity of my radiator had subsided already noticeable. The Warm White of old chips was warmer, the new has so a slight pink tinge through to white. There is no real warm-white, therefore only 4stars. The brightness is very good. Because it warmer the better I like it, I have with adhesive tape before the glass pane of the radiator a bright yellow plastic sheet geklebt.Die disc is only lukewarm. When installing, thermal compound and tighten the screws.
