Hello David,
The best way to find the best price is to do some hunting/research. Google "infocus 4805 lamp"
and wade through to find the best price.
You will find instructions on the lamp replacement procedure in the manual. If you dont have the user manual browse to www.projectorcentral.com and search infocus 4805 and on their spcifications page there is a "user manual" Acrobat PDF icon.
click on the icon to open the manual in pdf format

Take Care!

I recently had my lamp go out for the Infocus SP 4805 projector. When I replaced the lamp, the projection/imapges had discoloration in a couple of spots on the screen. not completely black, but discolored....


If you have not already found out, your problem may be a Light Tunnel Failure. It is common and can be corrected DIY. Replacement part is nearly non-existent and manufacturer repair is expensive.
For additional info go to www.avsforum.com and search for "4805 Light Tunnel". You will find threads about the problem as well as fixes. I also posted a DIY replacement option as well:

Powering On
  • If your InFocus 4805 projector is having a hard time powering on or doesn't power on at all, it could be one of two things. Due to the extreme temperature of the lamp that causes the temperature of the projector to rise, every InFocus 4805 projector has a cooling system. Check your projector's cooling solution, as it may need to be replaced. Also check the projector's fan---if the fan doesn't spin, the unit will not turn on. If the problem is the fan, you'll have to get it replaced. You can do this at the same place you bought your projector.
  • The Lamp
  • If your InFocus 4805 Projector powers on but does not project any light, the lamp will need to be replaced. All projector lamps must be replaced at some point---how often usually depends on how much use the device gets. Simply order a replacement lamp, unscrew the old one and screw the new one in. The projector will then work like new.
  • Color Wheel
  • If your InFocus 4805 projector powers on and is displaying images but the colors on the images appear warped or are not in the proper places, your "color wheel" will need to be replaced. The color wheel is a small device that essentially acts like a prism. Light is projected through it and it displays the appropriate colors on screen the way they appear in the original video source. Order a replacement color wheel that fits your model and use your instruction manual as a guide as you swap the old one out and put the new one in.

    It has a shadow on half the screen


    the light tunnel has collapsed. you can get the part from an infocus service center and do it yourself or send it to one for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

    When unit was turned off last night it "popped". Now it does not come on and the power light flashes at a rate of 1 flasher per second.


    the lamp blew. take it out and see if there is shattered glass inside. if there is, replace the lamp and blow the dust out of the projector. the dust keeps in the heat that the projector is trying to expel. the lamp probably overheated and shattered. otherwise, it was at the end of it's life (usually 3000 hours).

    How do i find out if i need a new lamp for my infocus 4805. when i turn it on the fan blows for a cpl secs and the green light blinks a few times, but i dont get anything saying the lampis out


    when you power it on, do you hear a high-pitched whir? if not, you need to replace the colorwheel. it's also the colorwheel if you hear a buzzing instead. if the colorwheel does not spin, the lamp won't come on. if the colorwheel is ok, check the lamp. is the screen on the side of the lamp clogged with dust? is the inside of the lamp bulging, spotted, or foggy? if so, replace the lamp and clean out your projector with canned air. dust blocks air flow and keeps in the heat. this shortens the life of your lamp and projector. if you do need the colorwheel replaced, you could get the part from an infocus service center and do it yourself, or send it in for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

    Infocus 4805 Lamp will not ignite after new bulb and reset.


    it there is no high-pitched squeal when it starts up, the colorwheel needs replacing. the lamp won't light without it. the part is under $50, but installation is quite involved.

    Sounds like the fuse popped. t5a=5 amps 250v=250 volts So you will need a fast-acting 5 amp 250 volt fuse
