Author Topic: Super Lumex Amps question Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 07-15-2011 09:11 PM                     My experience with these reflectors - seeing a 7inch reflector installed in a Highlight console with a 3k short gap Osram bulb installed. Throw was at 107ft filling a 32 ft screen with fL's at 23 using a blue ISCO anamporphic adapter Previous setup was stock metal reflectors using 4K Helios with less than a hundred hours on them and only doing 11's of the fL readings. Thus my take is: with such a small diameter of reflector but rather a deep dish reflector, along with the bulb sitting well inside, it's creating a more narrow angled and concentrated beam of light to where all of the light is heading out through the aperture plate. -Monte  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

In fact, it is the lamp that started that whole line of short-gaps (2000HS, 2500HS, 3000HS). The 2500HS is probably the hardest lamp due to its heat/dissipation factor. It is about the size of a 2K but has the heat/energy of a 3K. The Super Lume-X (a great lamphouse and optical system) really was not optimized to deal with the heat of the 2500...it is amazing how much better they do with 2KW, heat wise. If you do run a 2500...make sure you have LOTs of exhaust (which, on the dinky 6" stack, is a struggle..."if it aint whistlin', it aint enough") As to lamp/bulb...it is obviously a lamp...you don't have a "Bulbhouse" do you? It is a Lamphouse because it houses a Lamp. As to running a lamp for maximum life...if life is your goal...you would start it low (75-85% of it rated/not top current) and then only raise it enough to overcome the burn back of the electrodes, without respect to light output). The more you turn it up, the GREATER the acceleration of the light loss. I, however, care more about light output than longevity and would do as Scott says, turn the current up as it ages to keep the light output maintained. Someday, I'll post a graph of a xenon's light decay over its life. One thing is for sure...it decays MUCH faster in the start and end of its life than in its middle. It decays the fastest at the start though. At the end, the decay is normally due to its progressively darkening as current is increased to maintain lumen output. -Steve  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 07-16-2011 11:36 AM                     quote: Steve Guttag As to lamp/bulb...it is obviously a lamp...you don't have a "Bulbhouse" do you?

Not so. He explained why, something to do with the much larger size of that big fat arc cone, but beyond that, I can't remember the exact details -- it was about a decade ago when Technilite was first introduced to the Drive-In crowd. But I do recall even back then there was controversy swirling around over its efficacy, but the proof seemed to be in the pudding -- those who installed it swore by it's effectiveness in producing a much brighter picture.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 07-16-2011 10:14 PM                        I would agree that they help old Christie LAMPhouses a great deal. Others, not so much. You really need to compare the Technilite with a new old-style reflector/lamp to be scientifically valid.

Has this changed since 1998? Someone above refers to it having a rating of 85 amps. Thanks, Mike  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 07-17-2011 08:03 PM                     Louis... I have compared it to Christie SLC and Big Sky. Technilite offers about 20% more light with much more even converage. Admittedly though it does work best with certain lamps(bulbs for some of you) but thats not unusual for most reflectors.

Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 07-21-2011 08:54 AM                     A "lamp" is a light discharge device...it isn't restricted to something with a glass encasement. In fact, think of Aladdin's "Lamp"...oil based. Bulb is something to do with plants...though I guess due to its shape, some have called the typical "A" lamp a bulb...but it is almost always qualified with "light" before it since a "bulb" without a qualifier is ambiguous. (e.g. light bulb). How many of the lamp manufacturers also refer to their products as bulbs? In particular, their xenon products (since that is what we are talking about). Lamp is the proper term. Not that that this makes a hill-of-beans to anyone. A more humorous one is what people call carbonated beverages (as in the typical soft-drink kind). In the east where I live...they are Sodas...in the mid-west where my wife comes from, they are "pops" ...in the south where my relatives live, they are "cokes" (regardless of who makes the beverage or what flavor it is...you can get a nonsensical conversation of "what kind of cokes do you want? And say "Sprite" would be an acceptable response. To me, Coke is a company as well as a specific beverage. There is a cool program on right now called "How the States got their Shapes" and I really enjoyed seeing the part that discussed beverage thing as I have lived it! -Steve  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 07-21-2011 11:05 AM                        In Louisville we call them "soft drinks" I guess as opposed to "hard drinks;" i.e. liquor!

(and, may I be mean for a minute here: In a Christie SLC/SLH lamphouse, you DO screw in a bulb ...) .. okey, I'll stop.  |  IP: Logged
