The science behind Philips UHP "Ultra High Performance" projection lamps.
and provide a light source for your television or projector display. Philips lamps have very low failure rate
and are often blamed for another faulty component such as a bad ballast, color wheel, light engine, or
- If the lamp doesn't work, it may be another bad unit or component in your TV. Samsung and Panasonics are notorious for bad or weak ballasts. RCAs are known for bad color wheels and power supplies, which power your ballast, which powers your lamp.
Lamps with malfunctioning or intermittent ballasts will not function properly. Ballasts usually go bad due to overheating, power surges, or normal wear and tear on the unit. The capacitors on the ballasts usually store large amounts of energy to ignite the lamp with about 15,000 volts of electricity. Normal AA batteries are about 1.5 volts, so it'd take 10,000 AA batteries to turn on your lamp.
No standard multimeter tool can measure if the lamp is working correctly.
Lamps will not pass continuity tests because electricity has to "arc" the electrode gap to turn on the lamp--similar to a spark plug. Multimeters or Volt meters WILL NOT WORK.
All of our UHP lamps are OEM PHILIPS. We are one of the largest distributors.
Remember that UHP lamps need electricity to arc a gap like a spark plug to ignite. If the ballast is weak, or if there's something else wrong, the lamp will usually not light up. Call us and we'll help troubleshoot!
