Is your projector getting dim or has the lamp finally given out? Before you panic, check this out. This is a replacement lamp module (bulb and housing together) that fits a HUGE list of projectors. The key part numbers are BL-FP190E and FP190D (also known as NP36LP). It's a 190W lamp. It's compatible with tons of models from Optoma (like the super popular HD141X, HD26, GT1080, HD29, H182X, S310e, X312, and many more), plus models from NEC, Dell, Acer, BenQ, and others – you really need to check the long list in the description to be sure. The big plus? It comes pre-assembled in its housing. That means you don't have to mess with delicate glass or alignments. You just unscrew the old lamp door on your projector, pull out the old module, plug this one in, and screw it shut. It's a straightforward DIY swap that can save you a ton of money compared to buying from the projector brand directly. The manufacturer says they test these rigorously before shipping. Always double and triple-check your projector's exact model and old lamp number before you buy!
