Projector bulbs can be extremely costly to replace. in some cases it’s much more expense effective to just purchase a whole new projector instead of a new bulb. [Shawn] just recently discovered a good offer on an ‘as is’ Epson EMP-S4 on eBay as well as chose to take a chance. He presumed it most likely dealt with the exception of the missing lamp the seller mentioned. His suspicions were correct, as well as one customized LED mod later, his projector was up as well as rolling.

Without a stock lamp installed, the projector would provide an error message as well as shut itself off. So, the very first step was to cable up a bit bypass. when that was taken care of, [Shawn] installed a 30W 2000 lumen LED as well as customized in shape an old Pentium CPU heatsink to keep the LEDs temperature down. He likewise wired up the heatsink fan in parallel with the stock exhaust fan for great measure.  Optical lenses assist focus the light, as well as some customized wiring makes the LED turn on as well as off just like the stock lamp would.

In the end, his very first experiment was a success, however [Shawn] wishes to try an 8000 lumen 100W LED to make it about as bright as the stock lamp was. inspect out a bit video walkthrough after the break.
