Sylvania BriteArc lamp

[alapimba]

Hello
I have been doing a few searchs for a nice lamp for my projector and today i found sylvania BriteArc lamps. Anyone ever tryed this? Anyone knows something about this lamps?
This lamps looks goods and one guy from a lamp factory told me that this lamps are much better than HQI.

" It has an arc gap a third of the length of HQI so focusses much more light on the screen, it has a slim single ended design making the optics much easier, and a high colour temperature like UHP which is stable through life. It is a professional lamp that is sold for moving head image projectors found in discos and stage lighting.(...)We make them here from 150W up to 12,000W ratings. They sell for between about €75 and €4000 a lamp, and run on a standard sodium lamp ballast, same as HQI.
"


I found this info about this lamp:

i dunno where this information come from. looking the specs it shows me an arc gap (AG) of 5 to 6 mm. that's the same as hqi has. the lifetime of 2khrs is okay though in comparison to 6k of a cdm-t not.
wattage starts from 200W not 150W.
k the 250 is interesting. small gy9,5 base.

A GE CMH which is the same as a CDM-T but brighter has 12k hrs thats the one i use.

These 200w arent bad, but at the price they run at its not realy worth it ($125). USHIO make a good one.

trev and this lamps are better than HQI?
i'm asking this still related with my UHP bulp.. as i said i talked with one guy from a lamp factory about how to power up my UHP lamp, he gave me some help and stuff but as this seems to complicated and envolving so much voltage i asked about the HQI lamps.. and he said what i posted before and talked about this lamp. he wanted to trade my uhp for this bulb.. i assume my uhp and the light board has a higher value but well.. i was thinking about this...
I'm confused about this lamp things.. i wanted something easy to mount, small and cold

These are the CDM-T type bulbs they are referring to:

This is the Phillips bulb

The GE bulb is listed here Look down on page 4 at the CMH150 bulbs.

The odd thing on the Phillips spec is on the above page they are rated at 9000hrs, but if you then click the link for the tech data sheet they do list them as 6000hrs as IEF mentioned.

Thats cos ones designed lifetime and the other is average. You got to be careful of that and it looks asthough either they listed it wrong or its a selling point.

damn i so confused. i don't know what to do
i just wanted a small, cheap, bright, with a decent life and cold lamp. i'm using an hallogen of 150w and obvious is dark.. the size is great because theres no ballast i just wanted a bit more light...
this light stuff is really complicated

I dont blame you,

The GE has good specs but is a dud @ 200 hrs. The philips is ok but they cant make up their mind on the cri 96 and "up to 92" listed on the same page! (Who pays these guys?)

If you want a GE, the Arcstream 250W is the way to go. 10,000hrs 90CRI 6,000K 19000 lumens T15 which works well in an elliptical reflector.

The GE has good specs but is a dud @ 200 hrs

Ayyy?????? Try 12000hrs.

The best 250w to get is a 250w HQI-TSD

ok i'm lost...

I don't know what to get. And you guys already talked about so much lamps that i don't understand anymore

I asked about the BriteArc lamps because one guy was offering me this lamp in trade of my UHP. i know UHP is better but i can't power it up

If's they are not worth what would be a decent/cheap/cold/small light set to use with my 5" projector? It's for use with a 5" but something that i can use lately with a 7" projector that i'm planing to upgrade after do this one well.

Please help me
