Hi ywh
No It's a projector I'm olanning to buy, but I want to know if it's possible to find a replacement bolb before buying it.
Here is a link with some more info about the lamp.

I have ordered a 400w AC JYs-SE lamp and a 400W DC JYs-SE lamp for two projector projects I am working on.
For the AC one, can I just use a ballast and capacitor suitable for a 400W mercury lamp running from 240V
As for the DC bulb, other than starting, can I simply drive it from a DC supply with some form of current limiting - or is it "not quite that simple".
I was toying with the idea of feeding the bulb around 52VDC with a chunky 50W resistor dissipating the surplus (16 Watts or so)
I have searched the forums heavily for "DC PSU" DC ballast and so on, and cannot find anything - apologies if this has been covered before but despite searching hard, I could find nothing.
Kind Regards

I have ordered both an AC bulb and a DC bulb from the diypro.us website - so as and when they arrive, "Yes". 🙂
Will a 400w mercury ballast drive an AC lamp please?
I have already started to make a little switched mode DC unit -but if the AC can be driven from a mercury 400w ballast, then this should be lovely and simple.

Hi dmwarnke!
is your bulb 250W UHP? what is the word on the reflector?
Hi guymark!
the single end AC can not run in electromagnetic ballast. only double end can.
Hi Niels Bak
I can take moneybookers

Ahh, thank you for that.
If I order the JYs-DE lamp (Double-ended): 400w AC double ended, will this work ok with a 400w 240v electromag ballst intended for mercury lamps please?
If so I will order one of those - and think of something creative to do with the single ended one I have coming! 🙂

yes!

where will you intall this lamp? DIY projector? or Commercialization projector? what is the reflector? I can take off a ended of 400w AC double ended lamp, so you can intall it in a reflector, like other single lamp

It is an unusual application this one, it (may get two as 1 spare) is being used in a large metal reflector (ellipsoidal I think) to make a powerful search beam. I wanted an AC one and a DC one - but in the short term, I might get two double ended lamps for AC and use a sinewave inverter to do the DC>AC part.
I have a friend who lives in the Highlands - and many times amateur walkers misjudge the time it takes to come back down. He has used a 130W torch on more than one occasion to provide some light for them on their descent, but if at all foggy / misty, the beam has lost a great deal of its power by the time it gets there - about half a mile away.
Having bought a couple of these torches (huge metal reflector and heat resistant glass front), I am almost certain I can replace the halogen lamp with a 400w discharge bulb for him. This should mean that even from half a mile away, some serious illumination can be provided in an emergency.
I can also buy 400W ballast EXTREMELY cheaply at the moment (surplus) so that's a nice bonus.
So, alas not commercial, most of my tinkerings cost money, not make it 🙁
I was going to use a tile-drill to bore a hole into the protective glass window and then feed the other electrode out through that - and then place a SECOND section of glass over that for safety. I appreicate the offer of removing a cap for me, but not sure if that will really make too much difference. I can connect to a stud with a crimped eyelet easily enough and feed it through the hole I think thanks 🙂
If nothing else, it will be a fun project which ought to provide a bit of light on the mountains / hills near him.
I shall plonk an order for the two 400w AC lamps in the morning - lol and try and think of something creative to do with the AC and DC single ended ones I alreayd have ordered. I am sure I will find SOME way to drive them a bit lol.
Thanks again for offer of help on removing an end, but I think it will be ok as a double ender anyway thank you.
Kind Regards

Hi again ywh
Now I bought the projector.
And The lamp is an UHP 132W and not 120W as I wrote earlier.
A freind of mine, told me that he is shure i need a UHP replacement bulp that is different than the one you have told me. So now im a bit confused.
I have Attached some pictures of the actual lamp in the Projector.
