Where they the "domed" units (large bulky things with gull wing leads) or the silicone topped type? That is exactly why i asked, somone gave me a fixture that the drivers failed on (the dont like to go swiming) so i took all the LEDs off of it, In short, I have no idea if those LEDs are actually Bridgelux or a knockoff or a totally different die branded as Bridgelux because it's a familiar name.įor a fun read on this branding problem but with SD cards: There was a patent lawsuit between Cree and SemiLEDs that settled in favor of Cree, barring the import of certain SemiLEDs products. They make several spectral points, but no violets (despite seeing vendors claim stock they selling are Epistar 420nm, at $0.50 a package ) The other brand I see a lot is Epistar, which is a Taiwanese local manufacturer. I am unsure if Bridgelux sells phosphor coated chips, so who knows what phosphor you might be getting. Someone in China can take the actual chips and package them of course, except Bridgelux specializes in lighting so they will be 450nm only units. As for packaged units, they really only market white COB modules, at least domestically. Bridgelux specializes in GaN on Silicon chips which are their special sauce and much cheaper than the normal sapphire substrate for blue. I've always wondered if those are actual Bridgelux units.
