Yes I remember them but never used them. I also recall the square
glass dichroic filters that were around for Lowell lights in the
600-1K range. Haven't seen them much lately.
Dichroics were a choice for color correction before the advent of
the HMI's. They were quiet in the wind, being glass, and usually
were made for specific location fixtures. There were no clothespins
needed, like gels, and they were usually designed into the barndoor
structure of the fixture. They were fragile being glass. I do recall
the color temp being rather questionable but some people swore by
Anyone still use them these days?

Cool lights were first used on the TV series "The Rockford
Files". Legend has it that Jim Garner hated the heat put out
by the lighting techniques at the time. Slow film stock, and Brutes
and 9 and 12 lights the norm. I believe Garner helped fund their
development. A short time later, they were available in the rental
market, but fell victim to the HMI ground swell.
Dichroic lenses were available for open face instruments such as
Mighty and Mickey Moles. rendering a 2k a 1k (at best!), they fit
into the barn door ears of the before mentioned lights. They can
also be found in the same pile with the cool lights at the back
of most older established lighting rental facilities.

Used them as alternative to HMI's in reducing heat, I remember they
used 3400K lamps and so had a shortish life, but the thing worked
I can't confirm DYX are 3400, not home & don't have my catalogues.
They (it was Cool-Lite, no ?) said the 3400K lamps radiated less
Now they sell Cool-Lux, you know those obies for video cameras.
I think it's the same folks.
I remember these from the Mole Richardson catalogue - they took
DYS globes, the same globe that Tweenies used to take. The CoolLite
used dichroic over each lamp. The DYS is 3200 Kelvin or so. I think
that the short life was due to the design of the globe and its particularly

>Kool Lights", anyone remember
I believe Kool Lights were first used on the set of "Rockford
Files" in the seventies. Legend has it that they were invented
because Jim Garner hated the intense heat that was present on the
set. Blame 5254 and the Brute arcs, 9,12 lights, the usual television
lighting of the period. It is also believed that Garner had money
invested in these instruments.
They showed up as rental items soon after that, but were rendered
obsolete when HMI's became vogue. As far as Dichroic lenses are
concerned, I remember the glass ones that were made to fit over
open face Mighty and Mickey Mole Richardsonâ€™s. They would turn a
2k into a daylight balanced 1k (at best). You can find them heaped
next to cool lights in the back of older Lighting Equipment Rental

I distinctly remember 3400K lamps the first time we used it &
being surprised at this. I guess they weren't DYS, then.

Ah, yes. You can get two-pin 150W dichroic-reflector bulbs for the
Cool-Luxes. Anyone know whether those are available in Edison screw-base
configuration for use in Lowell L-lights?

I used them on a short film a couple of years ago because we didn't
have the budget for big HMI's so I ordered 2 of the 9-light Maxi-Brutes
and a bunch of individual Mole-Pars and had them all stocked with
dichroic PAR64 globes. It was a night exterior and I mounted the
Maxis and the Pars on a condor and used them to light up the location
which was an exterior of a house at the edge of the woods.
I think I color temped them out at about 4600K, which is plenty
blue for my taste- about like putting quarter CTO on an HMI. They
worked pretty well as far as the amount of light they put out. But
one thing to watch out for is "fringing" of colors- If
you are seeing the ground and shadows, you will not get a single
sharp shadow like you would from a single source such as an 18K.
In fact you will get a sort-of multiple shadow effect from the multiple
sources with different colors halating (is that a word?) ever so
slightly. I think that we may have put some slight diffusion to
help with this problem, but even looking at the pine trees being
backlit I could see different colors being split apart like a prism
(hope that makes sense!)
But over all a pretty good solution when budget is a big concern.

I don't think they make FAYâ€™s any more...though I think I still
have a case of minimal hour globes back in NY somewhere...FAYâ€™s
have dichroic filters on the front of them, but they do not have
dichroic reflectors - they are regular PAR (Polished aluminised
reflectors) which are metal coating on the inside of the glass ...reflecting
a lot of the IR back out the front of the fixture, as anyone who
has warmed pizza on a mini-brute can attest. Having missed the beginning
of this thread, I gather the issue at hand is heat getting on the
subject, but I don't know whether the specific interest is in daylight
balance or tungsten balance.
This past summer I attended a demo of a fresnel using the new calcium
discharge globes that are reputedly tungsten balanced but with much
more light per watt (and therefore less heat per lumen as it were.)
Has anyone actually used these on a shoot yet?
LA based but off base right now.
I remember doing table-tops years ago with an LTM fibre-optic unit.
It was composed of a main box with an HMI fixture [of some sort]
with several ports...you could plug in a think bundle which then
allowed you to plug in a 'split' bundle, and so on until you had
fibre-optics down to 1/8" think...or up to 1" think. I
believe the medium sized tubes [1/2"?] had a cool arrangement
that allowed you to snap on tiny little fresnel lenses!
We could drill holes through sweep tables to aim the fibre-optics
where we needed them. We used these on NiQuil spots where we were
back lighting the tiny gel-capsules.
Of course, the director wanted another shot where the actor picked
up the box...and wanted the capsules to remain backlit...so I hand
them rig up tiny doll-house fluorescent tubes [about 1 1/4"
long] inside the box...run off a garage door control battery [we
needed like 18vDC for it to work]..had a tiny on/off switch which
the actor could control to save battery life between takes...worked
Anyone know if these LTM units are still around?

We bought a bunch of Fays last summer for our twelve and nine lights.
The difficult to find items are FBEs, which are the same thing but
with screw terminals, rather than ferules. Finally found some at
Barbizon in Denver.
(We use these in some really handy little lightweight aluminium
5 lights that were custom made by MGM who knows how long ago.)

If they were orange, they were made about 1976.
In pinch, FBE's can be used in Molefays, and screw terminals from
burned out FBE's can be silver soldered onto FAY's. Found out the
hard way, when we lost a neutral.
