Hello,

I have asked this question before and there was not much progress made.

I hate the SOLA magneic ballast for the CDM TD 150w RX7 bulb I have. Its huge, it's heavy and its hot.

I would really like to switch to an electronic ballast, but do not know which one will work.

I was directed to this thread http://www.lumenlab.com/forums/index.php?s...17334&st=40

This thread is unhelpful, because the one lighting expert who recommended a ballast had the information removed because it was considered advertising. Has anyone yet found or knows of a SAFE and usable electronic ballast for the 150w Phillips ceramic bulb?

I am also concerned about this

"As the newer, short arc 150W ceramic bulbs age, they may become polarised. The polarisation superimposes a d.c. component on the a.c. lamp current. The combination of the a.c. and d.c. components results in a higher than normal current to flow causing overheating of the control equipment. Because of this characteristic, suitable protected circuits will need to be used for the safe operation of these lamps. The most common is a self-resetting thermal cut-out which rests against the ballast winding. This switches the circuit off when the temperature of the ballast increases beyond the maximum permissible winding temperature. Once the device cools down, the lamp will re-ignite and the circuit will continue to cycle. Ballasts with this feature will be marked 'Thermal Cutout' or TH or similar."

Does the SOLA Magnetic Ballast have a Thermal Cutout, or are we all just waiting to burn our houses down?

Is there an Electronic ballast that would be safe and have a Thermal Cutout.

Safety should be our prime concern. We can't watch our movies if we are dead.

Thanks

I found this on the Phillips website

Anyone had any experience with it?

Thanks

I could not source that ballast in Canada, the Philips Rep recommemded using this one with the 150W SA

I have this ballast, but not used yet. It is pricy.

Price is not a concern to me. I guarantee any of us would pay unlimited amounts after an accident to bring a loved one back. I'd rather be safe first.

Anyways when do you think you might get a chance to test it?

Where can I get one of these?

Thanks

In Canada, I sourced this through Westburne Electric http://www.westburnedirect.ca/

Try Manufacture Contact page. http://www.advancetransformer.com/contact/...ype=distributor

I probably won't fired it for a few weeks I understand the need to have a completely safe projector.

If you're in the northwest, you can special order this ballast as well as the whole line of colormaster bulbs. All but the cdm 150-830 and 400w mogul base would be special order, however, with a lead time of about 3-4 weeks.

Hey Christof

Check this guy out on e bay. I bought his 250watt e ballast. He is very helpful and ships it lightning speed. If you have any questions he is quick to answer.

Cheers

Vossloh Schwabe electronic ballast:

for $160 it's pretty pricey....

It is my understanding that the M102 magnetic ballast is the typical ballast for 150W MH pulse strike lamps, but the M142 has the thermal capacity to handle the ceramic lamps. (ie. more thermal protection) I can't seem to find definitive proof on this, so please take this info with a grain of salt.

cheers,
