Actual new DLP Chips!
I've wasted $300 trying to save money by buying less expensive chips, but the chips I got, though advertised as new, were actually used, and they rapidly failed or didn't work from the outset. In contrast, the chip from Dynamic Lamps was clearly new, works perfectly, and was not much more expensive than the fraudulently advertised chips sold by the competition. Dynamic Lamps is the only vendor of DLP chips that has integrity; don't shop anywhere else!
