UHP Flashlight

[flashlighttech]

Looking for battery pack for this light. I have a (EUC 100 L) Lamp Driver. I'm using a Philips 100w UHP LAMP WITH A 1.3 GAP. Don't have a schematic for the lamp driver. I wired twenty eight 9 volt batteries to test the lamp driver.oo: I reached 238volts (these were used batteries) and was able to light the lamp for thirty seconds.:scowl: I'm looking for a board to make a DC to DC change from 12V to 250 or more at 500 to 700 MA. any ideas?? Thanks for your help. The lamp puts out 6000 lumens how is that for a flash light!! He He! :naughty:

The easiest way I could think of is to use a 12 volt DC to 240 volt AC power inverter and then feed the inverter output through a rectifier to get the 240 volts DC which you can then use to power the lamp driver.

Wow Wires Batman! That looks way too easy to get killed with.

If you are going to use an AC inverter and then add a rectifier, then you would need filtering capacitors to clean the signal, and that could get large. You could just connect an AC inverter directly to the AC input of the lamp ballast. I bought a small 300W AC inverter for that purpose.

Re: UHP Flashlight (Update!)

I found the circuit i needed. 125vac to 300vdc it was in the projector I parted out. I have more lamps and 300VDC to 25kv driver boards if anyone is interested to purchase and try to make one like this. I'm also looking for A housing for this project. Any ideas??? I was able to light the lamp for 15 min for a test. I used a inverter from 12VDC to 125VAC to power the lamp. It pilled 2.5 AMPS during the test. I'm going to look for a smaller inverter to add to my project. Any help would be appreciated.:naughty: P.S. I havent electricuted myself yet! LOL here are some pictures of my finds.

Have you considered a Thor housing?

As far as a power inverter, if the lamp ballast is sensitive, you may have to use a pure sine-wave inverter. If you already tested with a standard inverter, then a pure sine-wave inverter is not needed.

The smallest standard 300W I could find is by the name of "Intelligent". It's 6-1/4" x 3" x 2-7/8". They are on ebay, but NOT listed by the name Intelligent, so you will have to search for "300W inverter" and look for the packaging that says "Intelligent". It's clear packaging over a black inverter with a white sticker that says Intelligent in orange letters. I just found one that's $20 plus $10 shipping.
