Really? (or are you just guessing?)

Ship,
I miss-typed last night. We have a 100w halogen MR16 with medium screw base, not a 150w. The Q100MR16 is available in 10, 18 and28 degree beam spreads with lumen ratings of 8500, 4500, and 3000 respectfully.

100w is what we use also, very bright. Still curious in not having tried the 150w versions, this much less replaceable capsule of the lamp versions which could lead to capsule lamp solutions and further options.

Here is my list at the moment on 100w and 150w lamps. You will note up to 40 degrees but I doubt that given the snout of such fixtures such a beam spread would be that realized. I do stock the WFL lamps, but have my doubts on if it's any better or worse than a MFL for the fixture.

Thanks for everyone's input. Ordered 6 James Thomas 'Birdies' this morning.
BTW, there is a 150w MR16 called an EZK. We use some in track lites in our shop. Be careful not to melt your fixtures though.

Yes there is a EZK, it's a GY-5.3 base at 120v. I also have a note on it that it's "base down to horizontal" burn position for the GE version of this lamp. that could be a problem in a base up track light fixture - the filament for the lamp won't much support filament sag in this position and or cooling sufficiently in it now potentially burning up quicker.

My point before was that the birdie was in concept a low voltage lamp in the fixture using a small remote transformer. The PAR 16 or PAR 20 fixture respectively would as per a term be a 120v fixture. Never seen any of the type using a bi-pin lamp that were line voltage. This not saying that it would not work and work well, just never seen anything off the shelf doing this. 60 degree multi-mirror lamp, nice lamp indeed. Eiko/Wiko makes the same lamp but one with less in color temperature and half the lamp life but double the luminous output. A 100 to 200 hour lamp and you are using it in track lights?

Interesting that your lamp fits as the normal birdie lamp uses a G or GX-5.3 and the EZK uses the GY-5.3

GX5.3 = 2-Pin Round Pins Same Dia. Reflector 5.3mm oc. 1.5mm Dia. Pins, 5.2mm Long. (Low Voltage) (MR-16) (2-Pin & RM2P) (Round Pins, Sloped Sides to Base) (LCL at Bot of Ceramic Base - Where Pins Come Out) IEC

GY5.3 = Oval/Flat 2-Pin pin Reflector dia is 1.25mm. Pin Min Thickness is 0.7x2mm at 5.3mm oc. (LCL at Bot of Ceramic Base - Where Pins Come Out)

goes before optics.

Just had this conversation the other day. There is actually no real consensus on the "original","True", meaning of the word Gobo. "Goes before optics".A bastardization of "Goes Before Gate", Ghastly Brass Object, I think I like "Goes before Optics" best, but I think it's a mystery that may never be solved, like the Thermos, it keeps hot things hot and cold things cold. But how does it know?

Oh yeah and "Lime Light", actually comes from two different sources. As stated by others, a slab of Limestone was heated by directing an open flame on it. The flame was usually from Acetylene, yeah like the cutting torch in the metalshop. In the old days,however the acetylene came from Calcium Carbide (CaC2), basically a carbide lamp, like coal miners used to wear is a "Lime Light". If you ever see one up close, you'll notice a small round piece of limestone that makes up the "nozzle" through which the gas passes before combusting. The limestone heats up and a temperature of incandesence is reached, just like heating a piece of steel to white hot. While the light from incandescent steel is bluish white, the light from incandescent limestome is ....... Tada slightly greenish yellow, or lime colored. Since this type of light production was used mainly in spotlights in the early days of gas lighting, and was usually the brightest light available on stage the actors would "compete" to be the one in the "Limelight" . Now you know, and knowig is half the battle. < G.I. Joe >
