Ruby / Qualia lamp, pics added.

As most of you know the Bulb for the Ruby (Sony VPL-VW100) is a "Cermax" style/brand xenon bulb. (Sony LMP-H400)

Here is a supposed picture of the bulb itself



Here is one in the housing/heatsink




Although the going rate for Bulb with new housing in the US seams to be about $850 you can knock $200 off that price going overseas.

The real question is how much can you get "just the bulb" for as many D-ILA owners have been remounting just the bulb in their old housing/heatsinks for a few years now.

What we learned was you could go to a higher wattage bulb and extend the life of the bulb and not experience as rapid of a dropoff in light output in the beginning. Basically the power supply compensates for the higher wattage rated bulb and the bulb size/form was identical from 400 w - 500w. which allowed the 500w bulb to fit into any of the G series projectors/housings.

I'm pretty sure the same is true for this bulb too and the housing looks even easier to seperate and reseat a new bulb. just a clip on top and bottom?

Anyway, now there are many places to buy Cermax bulbs retail so finding replacements should be pretty easy. Someone out there knows a good cross reference number for the identical bulb to mach up with Sony's "proprietary bulb" model number. Or it may be time for some to do a little experimenting with higher wattage

Ruby bulbs for under $500? entirely likely.

I think you could fit one of these:



16 pounds of thrust at 120,000 rpm.

I think it's about 120db at Idle.

Tryg I think you are right. The Sony bulb has the ring in the front that looks as if it serves no purpose other then cosmetic. Ive dealt with Xenon for years with film and Im betting the same PS in the Ruby will still ignite and run several other Xenons close in power rating. I have a spare bulb and cage. I should remove the stock bulb and order a Cermax xenon and see what what happens. Im confident if we could find something that mounts securely into the heatsink and uses the same hook up it will work. I would be concerned with any giving off any additional heat as I think the projector was designed with a set temp in mind. I would not want to melt my Ruby

With that we could fly our projector in for service. No need for fedex

Wow,
If you can hit my only two objections to the Ruby:
1) High cost of replacement bulb
2) Dim projector when all "decked" out

You'll find another Ruby buyer.

That ring might be used as part of the design to improve heat transfer. Being able to replace the lamp at a significantly lower cost would be a big plus.

That ring looks like some kind of insulator. It looks white vs the rest looks like metal.

1. Is $650 high cost? if so we'll find a replacement soon and hack off another $100+

2. Darin/Alan already solved this issue

1) I'm used to $300 bulbs but if I were to push it to $550, I would. A bit pricey but doable.
2) I'm very tempted as I already have a Hi Po screen and my upgrade bug is driving me nuts!

But I must resist!

It's amazing how people obsess about a few hundred dollars difference in bulb price but they are willing to take thousands of dollars of losses each year on the depreciation of their projector...

I don't know about you but my projector cost me $3,600 (below cost) back when MSRP was $8k.
Did you get such a good deal on yours too?

I don't obsess over a few hundred $$ but I certainly don't rejoice in the fact that a throwaway part can cost me close to $1k.
But that's just me.
YMMV

Could anyone point me to the best source for a Ruby replacement bulb? I've seen internet pricing from $850 to $1000. Has anyone done the experiment with the 500w bulb?

I think everyone online is backordered. They may say in stock but if you call them they will tell you otherwise. I hope sony has not forgot about their Xenon lamps!

Just installed a new bulb in my Ruby that I got through AVS. So I had to disassemble the old one. The picture in the first post is the actual bulb.

The manufacture posted an article regarding their xenon tehnology being showcased at CEDIA 2005.
Here is the link: http://optoelectronics.perkinelmer.c...deo+Projection
I didn't find the specific bulb listed at the site. I would guess the bulb is only available to Sony. Does anyone know differently?

Did it make a big difference in brightness. I have 1200 hours on my bulb so I know I will have
to replace mine very soon.

I had about 1300 on mine. I had sent the pj in for service, it had developed a noise that sounded like there were crickets in the room! Well it turned out to be the bulb. Sony service wanted to replace the bulb for list price. They also did the hard start mod and checked the convergence.
I didn't notice much in the way of a brightness change with the new bulb. I'm using your #'s on 43 and 44 if that makes a difference.

I just got a LMP-H400 replacement bulb. I've about 1000 hours on the current one. Since there's a 90 days warranty on the new bulb, I'm thinking of installing it now and use the old one as a back-up. However, according to the instructions, I've to release the xenon gas first when I take out the old bulb, which means I cannot re-use it. Can I just remove the bulb without releasing the xenon. Please help. Thanks

I take that to mean it's O.K. to remove the bulb without first releasing the xenon. Right?

Thanks for your response, funlvr1965.

About your crickett noise, I have/had the same problem. I posted my problem here a few weeks ago but I described it as a matallic rattle, but cricketts work too. At the time I thought it was bulb related but other posters did not seem to agree. My noise stops as sooon as the bulb extinguishes but the fans are still running. Actually, my noise seems to have abatted somewhat recently for whatever reason. I suspect it felt the competion of the RS1 breathing down its neck so it has decided to behave. Anyway, just thought I'd chime in with a similiar problem. Glad yours is working well

He meant YES, you can remove the bulb w/o releasing the gas. It is my understanding that the gas release is to take place prior to bulb disposal.
