Upgrade your 'old fashioned' incandescent projector bulbs with new super halogen bulbs
Brighter Way Longer Lasting - Halogen bulbs (13,000 lumens strong ) replace the last century's CZA plain incandescent bulb (11,000 lumens). This halogen bulb has a 100 hour average life as compared to the 25 hour average life of the incandescent CZA. That's four times longer life

Additionally, halogen bulbs do not yellow down (color) with age (drop in Kelvin temperatures from white daylight down to be like yellowish indoor incandescent light bulbs). Halogen bulbs remain at high Kelvin temperatures (near daylight) throughout their entire life,

Well worth the higher price

For stereo projectors whence incandescent bulb burns out, both must be replaced to have matching color temperature. Not so with halogen bulbs.

Switching from Incandescent to halogen requires no modifications, just remove the CZA incandescent bulbs and install the halogens bulbs
