Can I use a store bought halogen lamp in an LCD projector? Answered

I have a Sony VPL-V500 LCD projector but I can't afford a replacement bulb($200-500). Can I use a halogen lamp from a lighting supply and put it in the lamps housing, drill a hole in the side of the projector for the cord? Here are the specs for the replacement bulb meant for this model. Any help/info appreciated. Thanks.

Hi there,

I found out during my instructable (you might want to check it) that halogen lamps are not good at all. The image is almost non-existant (I used a 100W halogen) while the color are in the deep yellows. That's because the color temperature isn't right (halogen give out a yellowish light), Some folks used HID lamps with good results.
Check this site (it's in french but the pictures tell the story) http://www.allinbox.com/modding.htm

Found this website, bulbs seem to be cheap enough.

The correct lamp is metal-halide, and built into an enclosure with a reflector. A replacement of a different type will not work as well, but look at what people have done - e.g https://www.instructables.com/id/LED-Projector-Lamp-v10/

Thanks, I took at look at that link but once again, it's to complicated. I just want to put a bulb in the housing and run a cord out the side of the case(drilled hole), no rewiring. I agree with you that it won't work as well but that's all I'm willing to take on at this point.

good halogens give of 20-22 lumens per watt,so the math say's your replacement will generate 5500 lumens! that is fracking bright!!

a little research say's you can expect about 70hr's of use with halogen and 1000+ for halides.

The long term usage isn't so important I just don't know if I can get a bulb bright enough.

A really good projector will throw off an image @3000 lumens, even if a halogen is giving you only 12 lumens per watt that is still around 3000. go for it.

hmmmm, maybe this won't work so well after all.

. Since the unit was designed for a 250W lamp, heat shouldn't be a problem (assuming you replace it with another 250W lamp). Color may not be perfect but you should be able to correct or ignore. Focusing might be difficult but not impossible. I'd check out some of the LCD projector iBles on this site and then go for it.

Should I buy a halogen bulb or regular bulb?

. I'd go with a halogen if for no other reason than the color balance, but I'm no expert on this kind of stuff.

Thanks, I found some other posts on this but most people did some rewiring which I don't feel confident doing. I think I will go ahead with my plan since you don't think heat will cause problems. Thanks.
