GLC lamps (these were made for the new Strand fixtures)
That’s what Strand Claims
in certain versions of the 360's for longer life,
That would be the GLA for the long life
and also was told that lamp selection for 360's is primarily based on the type of reflector version in the Altmans. ??? it’s the same basic G9.5 base with a 60.3 to 60.5mm LCL
Only difference I have been told in the reflectors is that the "hammering" is smaller in the new ones vs the larger "square hammering" in the older reflectors. Can you confirm this is true or not,
The new reflectors are rated for the dichroic lamps be it HX-600/FLK series or GLA series. Higher heat plus they might be also dichroic coated for the cool beam and passing the heat thru the reflector. In my experience, use what you have until it wears out. There are no adverse effects other than that. That said, there are some early lot numbers of the 360Q reflector with an opening that’s a bit small to be fitting a T-6 lamp in it. This could cause a problem.
and that a different lamp should be used in different reflectors?
That’s the Altman official company line due to liability. Trust me, there are no real differences in heat between a EHG and a FLK/GLA lamp.
Is there a way to tell the different reflectors other then guessing by looking?
Nope, you have to look at them.
I have been using FLK's in some older 360's, and they tend to blow out after 100 hours(but they are cheapo FLK's)...and HX600's in 360's have been better but not by much.
Same lamp. The HX600 is the Thorn/GE temporary designation of the lamp from when it was designed. The FLK is the ANSI lamp based upon the HX-600 design. It’s all in the brand. Wiko might be cheap if this is your lamp, but quality control can be a bit sketchy. Check your dimmer curve to ensure it’s giving a lamp warming power. Also you might set your dimmer curve down a little considering these are 115v lamps usually used over voltage. The FLK/HX-600 is also a very fragile lamp (High output/short life) if you switch to a HX-603 or GLA/HX-605 for long life, or HX-602 or GLC/HX-604 the 604 & 605 being Thorn’s designation of it, you should have shock resistant lamps, and lamps with better more hearty filaments. I recommend the Philips GLA lamps, they are the best for output and life with shock resistance.
Trying to find a good lamp (to give a 1k output without using an FEL)
Try the HX-754 or HX-755 new from Thorn. They are only available from Nelson Lamps and all the data is not available for them yet - my personal little war with GE, but I expect they have the exact same performance as a HPL 750w/C lamp from GE which is 5,500 Lumens less output from 2,7500 Lumens on a FEL. L.E. Nelson Sales Corp (702)367-3656 Nelson doesn’t have a website... By the way, the BWN is more powerful yet than a FEL You could also go with a Ushio HX-800 lamp. It has the same 22,000 Lumens in output, and is the same lamp for all intensive purposes.
but with the reflector topic no in my mind, I'm not sure which way to go. In the past I have always used FEL's etc,
FEL lamps are not rated for Altman 360Q fixtures, only the Zooms. If you have not had a problem with reflectors using the 1Kw lamps, you won’t with anything below. Major difference is anything is going to have a smaller filament than a FEL lamp so even if it’s luminous output is less, and wattage less, with a more point source of light, it’s going to probably put out about the same amount of light.
Let’s talk lamp bases. That should be your real worry. The original lamp base Altman #58-0017 as well as #58-0018 the high temp one with a heat sink are discontinued. They don’t work well with high wattage lamps much less the dichroic lamps anyway. That does not mean you need to change lamp bases, like with the reflector and gate reflector assemblies, they are prone to wear out quicker but use them until they do. Than buy the Altman #97-1580 lamp base. It’s much improved. Otherwise, Ushio sells the C3A lamp base. Many people swear by this lamp base, and for all intensive purposes, it is the same, just not recognized by Altman or any known testing company for say a UL certification.
but the HX and FLK's are brighter, and use less power in a dimmer, and these 360's need the help cause the output of some of them is horrible no matter how much you bench or clean.
Check the lenses, are they green or blue?
Suggestions for figureing out the best lamp? These vary in age from 5- 10+ year old Altmans, and all have the new speedcaps. I'm also thinking the cap is part to blame for some of the poor output..but thats another topic<g>.
Explain please, I’m not aware of such a complaint.
Altman fixtures, I know them so well. I have exact notes on this whole subject in depth if you would like, including data passed along from the engineers at Altman. By the way, I was one of the first people in the US to have a HX-600 lamp. Robert Altman personally sent it to me following a phone conversation with him - me a young college having written a nasty letter of complaint after I did not get some parts in time for a show. Long story. Very cool lamp and I was impressed. Still use them in my Altman 3.5Q5 fixtures.
