Na, it's easy to match the output and
color temperature - just need the right lamp for your needs. For
color temperature, the FLK/HX-600, GLC/HX-604 and HPR 575/115 all have this 3,200̊K
color temperature and 115v
rating to match up with a
HPL 575w/115v+. The FLK & HPR also have very close to the same luminous output. GLC is only 15,500 Lumens in output but has a similar sized 9x7.5mm but more rugged C-13D
filament.
Assuming we are talking about the high output 575w versions of this lamp and not the long life versions which you should be using out of cost effectiveness given a lower budget. Let’s
face it a few less lumens or degrees in
color temperature are not going to make or break a show. Not being able to afford lamps thus less fixtures available will
effect the show. First is academic for comparison in what lamps you should not be using. Far below would be the lamps recommended for each
fixture given a lower budget application.
For the high output
HPL 575w/115v+ \
HPL 575w/C version:
In the L&E
fixture, you won't be able to match the graphic quality of the
point source of light coming out of the
HPL lamp in a S-4 with it's more refined optics and smaller
filament for say doing
gobo patterns; but for
color temperature and luminous output plus just as
flat a field of the beam install a HPR 575w/115v lamp into the L&E
fixture and it's going to be remarkably similar much less much easier to
bench focus.
A
HPL 575w/C with it's G-9.5 HS* lamp
base has about a 9x6mm to 9.5x6.8 \ 4-C8
filament. 3,250̊K; 16,520
Lumen; 300hr in life. (Slight variations in the above specs dependant upon brand.)
A HPR 575/115 with a standard G-9.5 lamp
base is a 6.35x11.68mm \ cc-8
filament. 3,200̊K; 16,500Lum +
Reflector; 300hr lamp life
Note both start with a very similar
color temperature,
voltage, lamp life and luminous output. Just a question of a internal lamp
reflector in a less efficient
fixture verses that of a more efficient
fixture and
filament but without the internal lamp
reflector.
A Osram #54549 HPR 575/115 lamp is based on a FLK/HX-600 575w/115v lamp. It's a slightly less efficient lamp type than the
HPL given a larger
filament size but the HPR un-like any other lamp currently available has a internal
reflector inside the lamp between lamp
base and
filament which completes the
reflector's ellipsoid shape in
fixture. This small
reflector disc at the center axis
point increases lamp output in a
Leko by 15 to 20% and makes for a more solid
flat field of distribution even in a less efficient lighting
fixture.
The GLC lamp will have been a better lamp to install the
reflector on given it's smaller
filament size and is still a better 575w lamp to do patterns with for the L&E fixtures but the HPR on the whole even in a less efficient
fixture by way of my testing has more punch than that of a
HPL lamp. This meaning given two similar beam angles - you can see the HPR beam of light clearly inside of a
HPL beam of light when meshed together.
You can match outputs and color temperatures even if mixing second and third generation fixtures by way mixing third and fourth generation lamps. The HPR 575/115 lamp is very impressive for doing so. Also and otherwise, the S-4 Junior is only rated for 575w. Want more output, install a 750w/115v GLD or better yet Phillips #13420-5 #6981P lamp (designed for the
High End Systems Color Command) into the L&E
fixture and it will easily out punch that of a S-4 Junior. It would also have something similar in output to that of a
HPL 750w lamp in the same
voltage.
But again, this is all academic, you probably should not be using any lamps rated for 300hr’s at 115v. Instead use 115v lamps rated for 1,500 to 2,000 hours for cost effectiveness. Avoid 120v
HPL lamps unless doing non-dimming.
The
HPL 575w/115vX \
HPL 575w/X lamp is a much better choice of S-4
fixture lamp for cost effective situations. 3,050̊K; 12,360 Lumens; 1,500 to 2,000 hours dependant upon the brand. Get over it, what looks blue/white in comparison to other 120v lamps is simply not cost effective. This much less will still look bright on
stage.
For the L&E
fixture, use a either Phillips GLA lamp at 3,100̊K; 13,500
Lumen; 1,500hr, or for longer life a Osram GLA/HP-600X at 3,050̊K; 10,500 Lum; 2,000hr. GE/Thorn and Ushio also make them and lie somewhere in between by way of output verses lamp life. The GLA series of lamp won’t have as much output as the
HPL but will be close enough.
Otherwise if you have the amperage available, can’t
beat the 750w/115v GLE by GE/Thorn.
