Topic: Which "bare" bulb for my Panasonic PT-AE1000U?

I have a Panasonic PT-AE1000U that needs a new bulb. There seems to be a lot of bulb 'scams' out there.

I don't want to spend the $450 Panasonic is asking for to replace the bulb, and I understand the 'bare' bulb can be replaced fairly easily, and for a lot less cash. Where do you find these? Should I be trying to find out who originally made these bulbs and get one of those, or is there a better replacement bulb out there?

Side-note: I'm surprised there isn't an easy way to retrofit these older hi-def projectors with LED lamps. I wonder if there's a market for LED retrofit kits out there.

The projectors are engineered for the lamps they are using. Which means a high-voltage power supply with a feedback loop for protection. It would not be an EASY retrofit and would be way beyond the capabilities of most people. Also, LEDs do not yet put out the lumens that current projectors do.

As for your question about a bare bulb, there are scams for those as well. So YOU have to be 1000% certain that the bare bulb you get is THE CORRECT bulb for your projector. Do not depend on the seller to have the correct information. Yes, you can save some money doing that, but not as much as you may think. I can't tell you which one to get, but there are some people here that have, and successfully. So hopefully, they'll chime in with that information for you.

Sheridan pretty much covered the first part. No knowledgable person here that I'm aware of will recommend a replacement OEM bulb over a original Panasonic lamp assembly. The problem is that veteran members have seen more than a few posts from people who have burned out their LCD polarizers or their entire projector due to using a 'OEM' advertised lamp that ran hot and just killed their projector. Others have complained that they bought a bare bulb, put it in, and after 100 hours it failed.

Genuine Panasonic can be had for about $320...

Frankly, it's the way I would go if I cared about keeping my projector for another 2,000+ hours.

On the second note - LED doesn't exist yet. Or, more accurately, 99% of the projectors on the market above 1,000 lumens are not LED based. There are a couple of models out there, most notably from Casio, which are LED/Laser hybrid engines, and the optical assembly is completely different than the lamp based modules which are currently in use.

The problem is that LED is simply nowhere near as bright as HID lamps which projectors are using. This has significantly delayed the rollout of LED projectors for the mass market. Though we have seen 500+ lumen models of LED in micro projectors, it is only this year that Viewsonic has stepeed up wtih a laser/LED hybrid home theater model at 1080p resolution...

The projector was pretty poorly received, and cost as much as a good JVC, Sony, Epson, or Panasonic would run. Let alone a cheaper model which outperforms it significantly.

AV_Integrated - It might be a good idea to pin a new topic at the top of this forum for discussions of 'generic' lamps. With all the people trying the cheap 'eBay' bare bulbs, and all the horror stories, it would be a good pinned topic.


mcaskey - Here's my experience with a cheap eBay lamp that I posted here Nov 1 2012:


Last year, I bought a replacement lamp element (Chinese bare bulb) for my Epson HC720 from eBay for about 1/3 the cost of an Epson lamp.

The replacement was about as bright as an Epson original, but there was a hot, almost burning smell coming from the projector after installing. (I decided keep using the lamp even with the possibility of overheating damage since I wanted a 1080 projector anyway.)

The hot smell diminished at about 400 hours, but so did some of the brightness. At around 900 hours the generic lamp started getting noticeably dim - way less than the 2400+ hours on the original two Epson lamps.

At about 1000 hours, the eBay lamp blew up. No loss as it was too dim to watch by then anyway.

Then I put in a new, genuine Epson lamp. The HC720 looked as good as new, so at least the generic lamp didn't fry anything as far as I could tell.

In the final analysis, the short lamp life, so-so brightness, and high heat made the price of the generic bulb a poor value.

No more generic lamps for me...

Thanks for all the insight, everyone.

Sounds like the LED retrofit is likely a bigger project than I have time for right now.

As for bare bulbs, I get your point that there are bulbs I shouldn't be putting in my projector. A local TV repairman told me that Panasonic never made bulbs for their lamps in the first place. He said that Panasonic only designed the lamps, made the housings, and specified the bulbs, having them made by companies like Sylvania/Osram, and Phillips.

Wouldn't it follow that one could go directly to a distributor of that bulb, and save a little moula?
