projector 3000 lumens would be possible to to change bulb to 5000 lumens or would i need to buy 5000 lumens projector?

It's possible someone makes an LED retrofit that runs cooler and uses less power, but a new projector will just be better in other ways as well, including resolution.

Problem is that ~65"+ TVs are cheaper than projectors and much brighter and clearer. Business meeting rooms are scrapping projectors for large TVs on the wall or behind hinged white boards or art..

I'm pretty sure that if 3000 lumens isn't bright enough, 5000 won't be either. And anyway, the power supply in the projector won't be sized to handle a more powerful bulb.

might be possible, but you would have to check your projector settings. The Fan may not generate enough cooling for a 5000 lumens bulb, which could cause problems or a noisy projector. If it doesn't cool properly it could cause a fire or burn out a lot quicker as well.

It doesn't work like that. If you need 5000 lumens, then you need a 5000 lumen projector.

If you want a brighter pic your looking for 5000 lumens if that is what you are looking for.I wasn't sure too dude.I'm still thinking if brighter means clear better brligher picture.I saw some projectors on Wish.I'm hesitant too cause i want to pick the best projector.I hope you find the right projector dude.Also don't forget that projectors can go up to 8000 lumens too if you want something brighter for a 120 inch projector screen.

Most projector bulbs are custom fit for the product. heat dissipation, size. power requirements are all set by the projector. Its notlike screwing a different wattage bulb into a table lamp, so not very likely to find compatible bulbs with much difference in output, though it is possible to find non OEM bubs for projectors that offer less than standard output, (As in cheap knockoffs).

No that is not possible. The first problem you will find is that the 5000 lumen bulb WILL NOT FIT in the 3000 lumen projector.

Plan on buying an entire new projector.
