You should contact a big lamp distributor such as Bulbtronics, Kennedy Webster, Techni-lux, Barbizon, etc. and see about the availability of the MSD 250/2 lamp for those MAC 250s. That is a very old lamp. You would want to make sure they weren't discontinued by Signify (Philips). You are much...

EHSTD,That looks like a custom socket from either the manufacturer or another socket supplier (Bender & Wirth?). The TP27 (Part # 69725 TP27 NO LEADS) is likely the only one OSRAM has without additional bracket hardware that might fit, as JMBrowne notes. You can often find those at...

Next year pushes out even more. How long before it's held over Christmas at this rate? 24 SHOW DATES: Dec. 8-10 Las Vegas – West Hall LVCC

Pretty much echoing what JT and Derek said. The voltage drop is common and it's based on the distance the electricity has to travel from the source (wall). The closer you get the lamps to the voltage they are receiving, the closer to "normal" spec they will achieve. If you use lower voltage...

I've seen a lot of the bigger rental houses selling off their "older" inventory, or donating it to the smaller community theatres-- who for them a 25 year-old Source Four is a huge performance upgrade (for relatively little money) from their 1970's Colortrans or Lekolites. So the "Hand me downs"...

Leaking press seals, especially when it's a bunch of lamps all out of a single box- is 95% of the time related to the shippers tossing the box about or roughly mishandling it. That type of jarring force creates micro-cracks in the press area, and the lamps tend to then degass once they heat up...

BVWs, BVTs, and BVVs are once again available. For a year or more OSRAM and USHIO both lost the ability to manufacture them when the one company who made the P48s bases that we both used went out of business (during COVID). We have a new source we brought online and paid for tooling at, and we...

House lights are General Lighting, General Service lamps (ie. Sylvania branded product). Those are and will be phased out. Tungsten Halogen Lamps for special purpose markets (OSRAM branded for use in Theatre, film, Microscopes, Rapid-thermal-processing, Airports, etc.) are all exempt (and will...

"...Working in a Mid sized venue and we are looking into replacing all tungsten stock for LED."Posts like this make my soul hurt. :(

Also- talk to SHIP on here. If anyone knows where to find old fixtures, it's him! :-)For the Syncrolite Mini-Arc, maybe try Paul Rabinovitz at Strong Lighting. Strong bought Syncrolite years back, so they have the best chance of having any old fixtures lying around that aren't in private...

The lamp looks pretty good (no obvious signs of heat issues), so I agree with Ship that it's likely a faulty ballast component causing the error code and shut down behavior as a result.

>>An HPL is about $15. How many years do we really need to squeeze out of it?AMEN, Brother! The potting cement tends to dry out after some time (many years) if stored in an arid location. Likewise I've seen nickel-platted stainless steel lamp bases on Followspot Xenon lamps get rusty and...

Just to clarify- unless you are running the fixtures at 100% intensity AT ALL TIMES, you will get far longer than the rated 300 hrs. avg. life. That is the average lifetime of lamps when run at FULL, 120 minutes on, 10 minutes off. If you dim them at all during their use, or run them at 95% or...

well... PART of the reason lamps are becoming scare is because you all have switched to LED fixtures. IF you stop buying lamps (or buy a lot less), they becomes scarce. You reap what you sow. You want HPLs to stay around forever? BUY MORE OF THEM.:-)

Sadly, no ballast replacements are possible. The fixture was built as a single unit, IP65 and sealed, and so we never brought in any spare components. If it failed under warranty you got a new fixture. There was no possibility to fix it. NOW-- the improved 2nd generation series I had gotten 95%...
