The EHG is very similar to the FLK/HX-600 in output in real life - what you can see on
stage. The FLK is a high output, lesser Wattage but lower
voltage and lesser life version putting out about 800 watts worth of light for all intensive purposes. Due to it's smaller
filament, it's frequently even brighter than a 1,000w FEL lamp but that's more light being used within the
filament plus
voltage drop, not better output.
FLK lamps at 575w/115v are a more efficient lamp that when operated at normal voltages with a EHG or EHD lamp, and the
fixture will seem much brighter than a higher real output but higher wattage lamp given the over
voltage color temperature. They can be used with four per 2.4Kw
dimmer instad of three also. That's the great reason to
switch to them.
As for brands, it's a high output lamp and early in technology design. There are industry preferences into what brand any one person will buy or what seems to last longer.
My home theater goes with Wiko/Eiko. The TD won't touch most brands but due to the 1/3 cheaper price for the crap quality control lamps, he goes with it for about $10.00 each and has similar dislikes about specific name brands as Wolf does. As if any theater with more than a hundred instruments could
track lamp life or even sees which fixtures blow out faster than others other than for
shin buster use. For him, it's a cost thing. Philips just started making a FLK lamp, or was that the
HPL lamp, in any case, it's not likely that this brand of lamp is that which is used in any theaters yet. I think it's the
HPL and they don't make a FLK. Yep, it's the
HPL lamp Philips just came out with, they don't even have a product number for it yet. Philips does not sell FLK lamps yet, but it's the
HPL 575/115/SL. By the way in waiting and loosing market share, Philips does now have the most efficient
HPL lamp on the market by fifty degrees in
color temperature at 115v.
Philips instead went with the improved FLK/HX-603/HX-605 lamp GE/Thorn also worked on but never really did much with. Philips says they were unique in it's design and it's possible, but the improved HX-601 in the form of the HX-603 from Thorn was out first. This lamp is improved on the FLK because it has a more compact and rugged
filament - does not break as easily. On the other
hand GE/Thorn was still thinking 120v back than for the improved version, and Philips mastered the GLC/GLA
line of lamp at 115v. In this desin, Philips was also hoping that their well done GLA
line of lamp, when they added a simple spring catch
heat sink to it would suffice for a
HPL lamp. All you need is a clip on
heat sink and it's now the same lamp no matter what brand of
fixture you have. Great idea, but
ETC did not recognize the new lamp and it never took off with the P/S
heat sink. What would
ETC do if the industry forced standardized things upon them again???
I still have a half case of them. They were sold at no more cost than the lamps without the
heat sink so why not?
The PhilipsGLA is the best lamp on the market for a high school. The heck does a high school need with high output lamps anyway? I would prefer my taxes were spent on them buying good lamps that will last 1,500 to 2,000 hours plus instead of a 300 rated.
It's pricing is not as good as the readily available FLK, but for 8 to 9 times the life, plus more rugged construction and smaller
filament, that extra cost is well worth it. In fact while in use, you might not be able to tell the difference in output between a FLK and GLA lamp. These lamps are that good. The GLC high output version of the improved
line of FLK lamp on the other
hand is not as bright as a FLK lamp. It's still got the heavy and more compact
filament, but by specification, the GLC lamp no matter the brand is not as good in output in comparison with even a standard and cheap FLK.
This is only for the long life lamp as opposed to the FLK or FLK/LL or HX-601. Such lamps are fine but not in the same output standards. In other words, the concept of the FLK lamp is about dead now - it's been improved upon in design. Ever notice theat the long life FLK did not come out with an
ANSI code?
Ushio and Osram, as well as GE/Thorn sell the GLA lamp now, it's just that the Philips lamp - in Osram's case the GLA is a re-designated HP 600X as is the G.E. HX-603 or 605 depending upon who's info you look at. But none of the others are anywhere near as bright or good in luminous outpt. Granted the Osram lamps are 2,000 hour and the Philips like GE and Ushio are only 1,500 hour. 500 hours in life you will also never notice the difference in. G.E./Thorn is the next best lamp, again at only 50 degrees different in
color temperature, you will probably never notice the difference.
For high output for all of you theaters with a budget, or those who want a lamp with a
bit more refined beam or more output but at less wattage, Osram's HPR 575/115v lamp is the best
Leko lamp at 575 Watts on the market. See Yeastrday about the 750w GLD/#6981P or 36982P lamp.
That
reflector on the HPR as I keep saying is the way of the future and something as yet is not able to be done with a
HPL lamp for a
ETC S-4, or able to be done by other companies. I tried it, and by chance, I was even wearing my free sample reward Osram Lighting Crew T-shirt yesterday. The quality of the beam of a HPR lamp verses a FLK lamp is enough you can see the beam of the HPR within that of the FLK's beam. This is a huge improvement in lamps and a saving grace to the otherwise sent out to pasture
360Q fixtures. Not only is it brighter, but it's a more even field of light than from any other similar lamp.
For a high school, I would
stock my fixtures with the Philips GLA lamp, than have a few Osram HPR lamps in reserve for special purposes. That or if I was edicted to the extra
intensity, go with the Wiko lamp for a FLK. This also depends upon amber
shift. If you plan on using your fixtures at even 75% for their maximum output, I would go with a lamp that at full already productes that output so you don't have to worry about
color correction.
Kind of like painting with your lamps to get them to max out for
color temperature in design. Given most people don' t have time or budget to swap out a lamp for a EHD or even lower HX-400, I would still stick with the above GLA.
As for the BTL -
Fresnel lamp, that's about a
dead end in technology also as with the FLK/EHG. It just stopped being improved earlier. That's unfortunate the rest of the
fresnel manufacturers don't stress the need for an improved
Fresnel lamp to keep up with
ETC's
Parnel. The BTL is a very rugged design however as it is. What's your problem with it? I can't see the
bulb weighing enough to fail by breaking due to it's own weight. What problems do you have and what brand are you using? If you are using EHG lamps in the Lekos, and only BTL lamps in the
Fresnel than they will be hard pressed to out match, than again, it's a
wash light and does not need to.
Anyway hope it helps.
