Wonderwall Projector Hack
Thanks for that link. I've read some on Lumenlab before on the Zoombox too.
Anyway, while sitting here, I decided to look in where the bulb mounts on the old model 'Sharper Image' (. Thanks togodzilla and joshua. Looked at replacement MR-16 LED bulbs at my local Lowes Hardware store and they were very expensive. I know I can get them cheaper online.

But evidently it's important to get the right kind, e.g. Flood (I think) and spot at a particular angle. I've read about people buying then returning several bulbs, but no clear winners that I can tell. May put this mod on hold for now. I thought the projection was so cool on my cheapie projector that I want to invest in a higher lumens model some time before next Halloween. Probably a 2,000+ lumens model of one kind or another so I can project a trail of ghostly shoe prints onto my lawn. But if I do find any good additional info on modding the Wonderwall, I'll post.
In the mean time, how much do replacement bulbs generally run on ~2000 lumens projectors? Maybe I'm mistaken and they don't cost $100+ a pop? If i actually had one of the projects to test out with bulbs i could find out make a good bulb. Ive been testing out some 10 watt leds that probably would fit the bill, they are blindingly bright.
Set one up with right right lens and it could be a good replacement Some projector bulbs can run 100 or much higher. I have seen a few projectors that use cheap bulbs.
I use higher end projectors in my haunt because i use them at home in the off season to, mostly they are rebuilt from a couple of projectors, cant beat freeish if i ever pick one of these projectors up ill try some lights and see what would be a good replacement.

Maybe I'm mistaken and they don't cost $100+ a pop?I bought a lcd projector from ebay 2 years ago.It is 1200 lumens and was under 300.00 I think it was 289.00 with shipping.It comes with replacement bulbs that are tubular in shape.I have yet to replace my orginal.It puts out a good projection for the price. Hey guys, I too just visited the bulb section of my Home depot to look for a replacement bulb for the generic 50Watt bulb in my Sharper Image Wonderwall projector.
I picked up a Philips Halogen Flood rated at 850 lumens (the most on the shelf). After installing it, I see little to no difference. Maybe the angle is bad being that it's a flood?
I had thought that the generic bulb supplied was crap and that a higher quality bulb would work. Next stop is ebay as some have suggested for an LED bulb. I've seen some 3x9watt bulbs that look good. As someone mentioned before, they are longer due to some additional electronics in the base. The good news is that the projector has some give in the spring mounted base of the door.

Wonderwall Projector Hack
I'll let you know if this works out.
What an awesome hack from. In summary: “The ‘Black and Bright’ projector hack removes the colour filters from a low cost video projector to double the brightness of its output, whilst removing its ability to represent colour (all images become grayscale, hence “Black and Bright”). The hack is usually destructive, and a replacement part needs to be ordered to restore the original functionality of the projector. The hack is really simple to execute (no soldering or electronics knowledge is required).” What you need: 1.
Projector: A single chip DLP projector (e.g., ) 2. Screwdrivers to open the projector 3. Pliers to snap the color wheel 4. Courage (you might destroy your projector) Steps: 1.
Open the projector. Locate and remove the color wheel. Snap the filters off the color wheel. Put everything back together. Turn on the projector. Projector Measurements To measure the increase in brightness, they used a. Depending on projectors, they saw results ranging from 1.4x to 2.2x increases in brightness (based on variations on color settings, measuring equipment, manufacturer differences in color wheel).
Model: OPTOMA EW 400 Brightness in lumens: 4000 lumens (advertised) Bulb Wattage: ie 240W Throw ratio: 1.28 – 1.54:1 native resolution: ie: 1280 x 800 full specs link: ie: Luxmeter reading of 9 points, on a 1m wide image, inspired by the official ANSI lumens test. At 1.28:1 throw ratio.

Brightness after hack: 4550 5750 3550 4950 5800 4550 5100 5500 3700 average: 4827 lux. 3017 lux per square/m = 3017 lumens.
