So, our projector had its bulb go <pop> last night and we need a new one. IMC says a replacement is on the order of $500 taking two weeks to get here. Asking some friends, I was pointed to myprojectorlamps.com which has part # CLMPF0056CE01 for $318, with shipping, in stock. Looking around more I get the impression that there are plain bulbs and bulbs in a housing, accounting for the price difference of almost $200. Does anyone have experience with these? Our PLS classroom is kinda dead without its projector. Thanks for any ideas & pointers! --STeve Andre'
