XENON SHORT ARC LAMPS PART 2

[WCRSLP]

Great project! Could one avoid building the big power supply and run perhaps a smaller wattage bulb (1000W) on a couple of 12V car batteries for an hour or so? When you spoke about a "blower", do you have a fan inside the searchlight?

[repalmore]

OLD BLOWER, not a nice way to talk about my mum:) Very well focused. Very good job mate. Cheers.

[ribvicky]

fuckin that would call the Aliens!!

[marcelgiglio]

now u can call for batman!

[seindich]

I guess if applied the reflector with greater solid angle it would be #@#$ brighter :)

are such reflectors (deeper like in christie or imax lamps) and huge are used somewhere?

[BankaiIchigo12345]

Ok, so where's the scene where he strikes the arc?

batman

[sonnytiger]

very cool

[aarontsmall1975]

See the ultraviolet reflection (Stokes Scattered), it is upshifted just enough so the Camera "sees" it?

[OnnomonnomonnO]

I bet that this must be fokin visible from the moon if you point it that way :DD

Hi , yes it will work but may not be seen as far as a higher wattage lamp.

[kijifled2]

Does anyone know if a 1500w 4200K lamp work for a searchlight? Is 4200k bright enough?

[douro20]

@kijifled2

4200K is the color temperature of the lamp. a 1500w lamp will put out right around 100,000 lumens, about 25 percent of that being short-wave UV!

Hi i always use gloves and face mask and and other gear when handing these but have not had one go off but have seen the vids you talk of ----[ shit for brains ]--- is all i can say , and yes they are made of quartz glass.

[spiderj8579]

@2wattage I work at a theater and I once had a bulb go off while I was handling it and if it wasn't for the gear that you use, I would have had some serious injuries. I loved this video and like to see what other uses these lamps could have. Did you have neighbors asking about the bright beam coming from your garage lol?

[Nivicoman]

Do any of these explode as you're handling them? I understand they run extremely high pressure as you stated. I have seen more than one Youtube video of people handling these without protective gear and they explode sending shrapnel into their skin. Is the envelope made of quartz or something more exotic? Oh and I found out long ago trying to run a camera flash/strobe beacon Xenon tube as a steady light source doesn't work well at all.

[2wattage]

Yes we are in christchurch and that is a 11000 volt pole transformer.

[danizzamoliv]

Hi I have the same lamp I got it from my father's Night Clab.

The lamp is XBO-Xenon short arc lamp 1600w osram

If anyone is interesting to buy it this lamp from me he can contact me on my e-mail adrress okce2@hotmail.com or on my phone 0038971486721 Ilija

[intheshitter]

Its like the Bat signal lol

[a380rockerfan]

where do you live? because i recognise the brand of that small grey pole transformer you have. i live in NZ, and we have that brand here too!

[douro20]

How many hours do they put on them before they throw them out?

[2wattage]

Hi i think they told me 1500 hours.

[douro20]

Hmm...typical warranty for a 5kW lamp is about 900 hours, and Osram's XBO XL lamps are warranted to 1200 hours so that is quite a long warranty life for those kinds of lamps.

[2wattage]

Hi , i did say '' think '' maybe it was 1000- 1200 , not many hours for the cost but i have run them for much more at partys, but i don't care if they go bang un like the cinema

[tragicpaper]

cost... sorry.,

[2wattage]

Hi i got it for free from the local cinema , they run them from new for a number of hours then dump them before they blow for reliability reasons, 15KW lamps I have seen and are used in the likes of Imacs cinemas. These lamps use specialised de-ionized water at very high pressures to cool them - for theses reasons I have not experimented with them

[tragicpaper]

how much did that 5kw arc bulb coast you. and would you know the price of the 15 kw., oh and nice vid.,

[Kalashnikov440]

all i have to say is....................DAMN!

[rickyatHK]

It got f**king HOT !

[ritmolatino0664]

Amazing, thanks for sharing....

[BenHutchinson1]

Run the thing out of the fixture and set the camera to auto-exposure so I can see what the actual arc looks like in the lamp between the electrodes. Please make a video like that for me.

[2wattage]

Hi and thanks for that, my friend and I had planed to fit a 15kw lamp from a imax projector to a bigger fortress searchlight but the 400 amp power supply and the high pressure deionised water for coolling all became to much so it did not happen.

[acoustics101]

A very impressive DIY project!!
