HPL that turned into an HELP
Still waiting for this thread to fetch a nice Xenon failure! Of course, generally they are so traumatic nobody things to take a picture!
That shouldn't be to rough to retrain the staff, I'll just have to use a mirror and talk to my self even more than I already do!Most likely a finger %@&! - touched lamp given what I see. Good advice would be to inspect the rest of your fixtures, see if evidence of this problem further from a saff member. Re-Re train your staff on properly installing lamps. No' they didn't do it but re-training on proper installation of a lamp is a easy.
Consistency is key!
Ah yes, the newer "Dimple" Filament design. This has been in place on a variety of smaller-wattage lamps (under 300W usually) for at least 7 years now. It's believed to be more robust than the design with mounts and supports which can break. It's also less expensive to make (I assume) as it has less components and fewer process steps as a result. Definitely NOT the result of an implosion.Got an interesting lamp failure for ya. I was cleaning up the technical storage area today and thought I'd investigate some NFG complaints of our "Starball" fixture.
Pulled out the little 100w halogen lamp and was greeted with this. A perfect little dimple on each side, with a glass straw connecting them, with the filament neatly draped over (couldn't blow air through it though - I tried). Seems like there was a mini implosion. One of the more artistic lamp failures I've seen in my career.
Unfortunately GE is no longer making theatrical lamps. Which really sucks, my old strand LEKO's loved GE FEL's. And the Osrams that we use now don't last nearly as long, and depending on which version we get don't even fit in our 2200 series fixtures. The ones with the metal base and rounded corners fit fine. The ones that are all ceramic have sharp corners and won't fit in the sockets.I'm amazed to read of these lamp problems. In something like 25 years of stage & studio work (1955-1980) I've NEVER had any such problems with General Electric, US-made lamps! Of any kind--large lamps (up to 10 kW) or small general purpose lamps. Is everything made nowadays foreign crap???
When I opened Theatre Aquarius in Hamilton, Ontario, Canada in the fall of 1991, our ellipsoidal inventory consisted of 246 fixtures, mostly of Strand's 2200 series as Source Fours hadn't hit the market yet. I researched lamp brands and everybody I asked said accept only GE FEL's but Ushio's would be acceptable for the 500 Watt and 1 & 2 K fresnels & PAR 64's. Our initial lamp order was 300 GE FEL's, to allow for our first years spares, and Christies supplied everything else as USHIO's. ALL lamps proved to be totally satisfactory with only one USHIO Iris Cyc lamp arriving damaged and immediately replaced. FEL's often cracked the lenses in the Strand 2204's and occasionally in the 2209's but that was Strand's fault for insisting they were rated for the 1K's and not GE's fault at all. Eventually, after Strand had supplied MANY replacement lenses, we agreed to lamp the 2204's down to 750's and that was the end of the cracking lens problems.Unfortunately GE is no longer making theatrical lamps.

I'm afraid GE is only focused on the mega-dollar products for large commercial and government operations. When it comes to consumer products, they are only a "brand" that gets licensed out to many other companies. This migration started many years ago. For example, all their consumer electronics branding was sold in 1988 to Thomson Consumer Electronics."Unfortunately GE is no longer making theatrical lamps. Which really sucks, "
Too bad. Maybe this will be fixed in the future . . . We hope!
@Scarrgo It's O.K. to run 208 volts THROUGH them so long as you don't leave too many volts parked in any one 6, 12 or 24 volt filament along the way.One day in the shop we were setting up some MR-16 4 cir strips for a demo, one of the guys grabbed a rack and plugged them in, as he turned on the breakers the came on super nova bright for about 3 seconds, then went out...so he grabbed another strip, same thing happened, grabbed another strip, same thing, while grabbing the 4th strip someone asked what he was doing, he explained his dilemma, and the guy freaked out on him as he had blown 60+ MR-16 lamps by running 208v thru them.
After asking why he didnt ask for help after the first one went super nova, his response was...."I thought it was odd, must have been something wrong...." was a lovely day...and here's your sign...
