But what baffles me more is when we order bulbs for the 515s and find out that they are on backorder. This I just don't understand

Were you trying to order the 330W bulbs?
I was told by our Sony rep that they made newer models for those, supposedly they won't fail as often.
They ran out of the older models before the new ones were ready.

The 330 watt bulb design was poor and has been replaced with a new design which has been working fine. Our bulb delivery has been overnight for warantee singles and 5 - 7 days for replacement set of six, non emergency.

In the small world of Digital Cinema….Ushio is the bulb manufacturer.

It seems like Ushio is doing well on their Xenon lamps but the smaller lamp modules like the ones that go in the NC900...well...things have not been so good.

They made a very recent change to the NC-900 lamp. The lamp itself is cemented in only at one end instead of at both ends (Duh). The un-cemented end has a new support to keep it aligned, my guess is they had expansion issues the lamps broke as a result. None the less getting all,those free lamps isn't such a bad thing. And you are still on screen anyway.

Sony has had the same issues with this same lamp!

And only one short year ago you were telling ALL how that was such a proven lamp that will do so well...yadda...yadda...yadda.

quote:
Biggest advangate of this projector IMHO are the lamps. There are no multi thousand dollar glass reflector, or heat filter in this projector. Each lamp assembly has it's own internal reflector. If a lamp blows... so what! Unplug it and plug in a new one... even while the show is running. You can basically let your lamps run till the light level is no longer adaquate [sp]. Lamps have a 3000 hour warranty and have been proven in other NEC projectors in the past. There are a few installation of it in Florida that are comfortably running on just one lamp!

NEC was also claiming how it was thermal cycling was hurting it (cooling too fast...addressed in firmware 4.214 and beyond)...there is also a power supply improvement...that isn't software fixable...hence there are two power supply software versions.

I sure hope the current version does do well. The other potential FU is that the lamp can/has take out the power supply card too and the NC900 isn't really built with service in mind (at least not too well thought out...it is more assembled in layers so you may have to dig your way into the thing you want to get to.

There's a current statement from Sony regarding this topic here:

Looking ahead to the future
Sony confirms that it is continuing its development of new-generation digital cinema solutions including an alternative light source. Promising significant benefits to theatre owners in terms of picture quality, brightness and colour gamut, operational flexibility, reduced maintenance and lower ownership costs, alternative light source will complement and strengthen Sony’s existing portfolio of conventional cinema projection solutions.

“We’ve always been committed to give exhibitors and their patrons the absolute best possible picture quality” confirms David McIntosh.

“Laser light source will be one of the game-changers in the industry in the near future. But it’s got to significantly outperform other solutions that are already well proven, and it’s got to be at a price that make commercial sense to exhibitors. When Sony does bring laser to market – at the right time, and the right price – we certainly won’t disappoint our customers”, says McIntosh. “In the meantime, we continue to support and evolve our best-selling family of industry-leading projectors that will keep on giving audiences an amazing 4K experience for years to come.”

Wouldn't this equally apply to the exiting solutions from Barco, Christie and IMAX? I've not yet heard about special permits being required for those, but I might be missing something.

Still true, at least according to an article in The Economist from December 6, 2014:

quote:
A few other high-end cinemas with deep pockets have signed up, notably the IMAX chain, whose staple 70mm film projectors are now rather dated. But there is no sign of a mass shift to lasers. The obstacles are not purely financial. At the moment, special licences must be obtained from the Food and Drug Administration, which imposes additional requirements on staff.

Laser-illuminated cinema projectors promise brighter and more realistic images

I've read about it in the past, but I didn't know it was still an issue... In any case, it's stupid.

You don't need a special permission to run a 15 kW IMAX xenon bulb, which in itself is a little bomb and can be equally destructive for your eyes if you look into the lens at close distance, but once you put in a bunch of lasers to do the same, it becomes highly dangerous and needs special red tape to be considered safe for public consumption...
