Extra Phillps CDM150/T6/942 Bulbs

[TaskMaster]

I have some extra Phillps CDM150/T6/942 bulbs if anyone would like any at a real bargain. The specs on the bulbs can be seen here

There are several places that sell these bulbs to give you an idea of the typical cost:
Bulbman
Atlanta Lightbulbs

There is someone on eBay selling them for $54.95 + $8.95 shipping
http://cgi.ebay.com/ws/eBayISAPI.dll...category=14984

Standard magnetic ballasts that can operate this bulb are available here:

There is someone on eBay with F-Can ballasts that are all enclosed and nice and quiet. He typically lists them with a $35 buy it now. The next cheapest I could find these ballasts is $71 and the three local electrical supply stores I tried each wanted over $100 for one:

There is a group buy underway for a cold ellipsoidal reflector that will fit this bulb. There is a link in that thread to Ace’s post where he’s using a similar setup and finds the output to be equal or better than a 250W HQI setup with a reflector and condenser. The other nice advantage is that the light put forward will effectively be cold, So no real need for IR filtering. The bulb is also listed as UV Blocking as noted on the bulb in the picture. You can see an example of the type of reflector (or even buy one) from the group buy here at Edmunds Optical (it is the 97mm).

The price for the bulbs is $12 + shipping. In the US $5 should cover it ($3.85 Priority USPS and $1.30 insurance). That is less than ¼ the price of these bulbs normally. Other shipping is no problem at actual cost (no problem shipping outside US, but again you pay actual shipping costs). Get 3 bulbs for $41 shipped in the US - that's less than the cost of one bulb anywhere else! When the bulbs I have are gone I won't have any more. If anyone has some good DIY projector parts you'd like to trade, just let me know.

PS - Just to note - I am PayPal verified.

Hi unit24,

I went to e-mail you but you have e-mail through the board disabled. Shoot me an e-mail and we can work it out for today if you like.

Thanks

I'm interested too. However, where can i find the base for it?
Thanks

Heya taskmaster, dont take this the wrong way but that bulb looks used, i can tell by the yellowing in the arc tube, it should be white when new.

Hey Ace, No problem - however please don't take me wrong when I say I completely disagree. I know you use the GE lamp, and I'm not sure if that arc tube appears different (and indeed should be different as you've noted their longer expected lifespans), but these bulbs appear identical to those pictured at both the Phillips and the bulbman site I linked to in the first post. I see no difference in these or the bulbs pictured at the Bulbman site , in fact if you look closely at the picture at the Phillips site , I'd say the arc on the Phillips site itself looks even more tinted. I combined a close up of a bulb I have with the pic from the Phillips site. It is below for illustration.

Well first off I should apologize to TaskMaster for my reaction to his attempt at help. I have recently noticed several questions asked on various threads that had already been clearly answered and the people asking them seemed to be mentally competant.

Taskmaster, I misunderstood your reminder to check the obvious and reacted very poorly. Please accept my apology.

As to the subject at hand, it seems that all that would be needed in addition to the bulbs offered and the F-can ballast kits for about $35 would be a socket. Is this correct?

After testing my small lcd with the old slide projector light source it seems that it will not need a very powerfull light source. It displayed clear and bright with the lights on and the shade up. This was only about a 36" diagonal projection, but my apartment has only an area with about 84" max to project on. I'm thinking that even as little as a 20% increase would be good enough in less light.
Opinions?

thanks

Hi Justme,

No sweat - I felt bad that you thought I was hassling you some way in the thread (and I honestly just thought that guy added the info after you looked), so it's all good .

Yes, a socket would be all else that's needed, unless you also wanted to setup some type of reflector. Getting up to an 84" projection with a 150 watt bulb may not be bright enough, but Ace or I Eat Flowers could probably answer better as they've got similar bulbs in use. I am planning on somewhere around a 60" projection and based on the shots I've seen it should be plenty bright.

BTW - 4 bulbs left for anyone interested.

Here is a place with a socket .
