I got my new lamp. It is for commercial projection use. people use it to replace the

[pinkmouse]

They look like Osram HTI300 lamps to me. Very nice colour rendition, and if you don't keep trying to restart them when hot, and run them for at least half an hour each time you turn them on, then you should get around 800hrs of useful life.

Make sure the pinch seal on the capsule faces down, or they could explode. You will need UV filtering!

Here a link to a lot of lamps:
http://www.eurotekmarketing.com/lamps/lampsnew.htm

you can see there the HTI 300W/DX


BTW

I found a lamp: OMNILUX ODM 150W G-12 6000h 6000K .
with the same 230v like the CDM-T 150/830 Lamp(same ballast).
About a 9000-11,000 lumen

search in this link for "OMNILUX ODM 150W" (you also have english ver to this site)

ywh

Were can I buy this bulb and ballast ?



Thanks

The lamp / ballast set was bought from a factory near me, but they
don't do export. the ballast is 220V only. To make it accept 110V
input, the ballast needs to be modified. The manufacturer requires at
least ten sets to be ordered in order to make such change.

18wheeler is going to setup a group buy. You can contact him.

18wheeler ! the screen is 100',

I have set up a groupbuy for this short arc lamp / ballast set. The page is here. The thread for the group buy is here

ywh,

Will this lamp work with a 250W electronic ballast or will it only work with the supplied ballast?

I'm asking because I may buy several lamps but if the ballast was to die then I could use a locally available eballast.

 

[ywh]

I am tied up with the work right now. More pictures and comparison
will be posted once I have spare time ( in a few weeks).

So far, picture with this lamp is brighter than 250W HQI. in the
picture posted above, the sky is almost too bright to stare at. My
eyes hurt when looking at the bright area. I also feel the picture is
sharper and contrast is increased. Comparing to this lamp, HQI seems
to have a 'softener' lens on.

I tested emitted heat by putting my hand in front of the light. It
feels cooler than HQI. Heat glass is no longer a must-have. Also lower
speed fans can be used, so noise can be decreased too.

it might, but I doubt a normal ballast can power it. the tructure of the lamp is very much like a small version HMI 575W. HMI uses very different ballast as far as I know.

I also feel the picture is sharper and contrast is increased. Comparing to this lamp, HQI seems to have a 'softener' lens on.

It is expected because there is less defused light, which would blur the image.

whats the story with bulb life?

> 2500hr (replacing, not failure time) or 800hrs if treated well like pinkmouse says?

oh yeh and if you're gonna order one of these prime, maybe we could do a group order... any other aussies are keen?

 

[prime]

Osram seem to have 2 different 300W HTI lamps, one with 750 hour life the other with 3000 hour life. so I hope ywh's lamp is like the 3000 hour type. Here are the catalogue links:
http://catalog.myosram.com/srvc/z_catalog/!?~language=EN&~country=ZW&it_p=4050300370651
http://catalog.myosram.com/srvc/z_catalog/!?~language=EN&~country=ZW&it_p=4050300651248

bodgy: I was thinking that there may be other aussies interested so we could ask ywh to send ours direct to Australia.

I'm currently using a 150W (osram HQI-T/Sylvania HSI-T) lamp with 8mm(?) arc in my OHP retrofit with SGI 1600ww (only using part of lcd), I was previously using 150W lamp with 17mm arc and there is a definite improvement with the shorter arc so a 3.5 arc will be even better. links for my current lamp:

ywh - the 220 ballast is good for me , In Israel we use 220v.

BTW can you see my mails?

The lamp is not a HTI300. The manufacturer has rated lamp as 2500 hr. Hope ywh will get more specification from the manufacturer. then we will know what it resembles.

 

[ywh]

The lamp is not an ordinary MH lamp. The manufacturer stated it as UHP
(ultra high pressure) lamp. On the other hand, I used HTI300, the lamp
was very hot, print paper will be scorched at 8cm away, 250W HQI will
do the same at 3cm distance, and this lamp is cooler than 250W HQI. I
havn't test the "scorching distance" yet.

hi shlomid

I won't mix 250w lamp with a 150W ballast. Most likely it won't light. And there is danger that the ballast might be damaged. but it would be fun to try out 150W lamps that ywh has.

 

[shlomid]

The projector is Hitachi CP-S830
