LED lights in Elinchrom mount...

I am interested in figuring out how to mount a good LED light source into Elinchrom light modifiers to get a continuous light source without generating too much heat.

The Rotalux deep octa instructions ask you to limit your modeling lights to 300 Watts, presumably to keep down the heat.

So LED lights will give the most light per Watt. I have seen 50 Watt LED bulbs which claim to produce as much light as a 350 Watt tungsten bulb. There are LED bulbs with reasonably high CRI numbers.

I am open to any purpose-built photographic lights as well as any reasonable DIY solutions.

And just to head off the side-tracking conversations :), yes, I do know the advantages of using strobes over continuous lights and yes, I use strobes regularly and will continue to do so. This is about adding capability.

In, following. We have several Elinchrom modifiers but putting continuous LEDs in them sounds interesting. Sometimes I'll use the modeling lamps for continuous lights.


The modeling lamps on even my little Elinchrom D-Lite 2's get pretty warm, especially on high (non-proportional) brightness, and especially in an enclosed modifier. Subjectively, I would think that even the brightest LEDs you can get your hands on will generate less heat than the modeling lamps.

I think so, too. Tungsten lights clearly generate serious heat.

There are heat issues with LEDs, but they don't kick in till much higher levels of light output.

One option I have considered is using this adapter, intended for speedlights, to hold a socket in place with an LED bulb.

The only socket I have right now has an integrated umbrella adapter built in and it won't mount properly. I'm trying to find a socket which can accomodate 100 Watts (haven't found a standard e27 LED bulb larger than 50 Watts yet, but I suspect there will be one). Preferably the socket will be at least ceramic or have some other means of dissipating heat.

Some bulb options:

This one is 95cri! Daylight balanced and Includes a snap on tungsten filter.

No one has any thoughts on this? I guess I posted it in the wrong place :).

If it were for me, I would figure out a way to make the Alien Bees / Paul C Buff "DigiBees" work. The LED modelling light really rocks! Weight, price and support in North America are contributing factors in my choice.

I have seen people rip the guts out of the Alien Bee cases and integrate the strobes in a number of "solutions".

Best regards.

400 watt equivalent, daylight balanced, fan cooled LED...you might be on to something. Plus, it could be fired as a strobe, too.

I wonder if the any Elinchrom's will accept an LED bulb or if it is proprietary. The Rangers have LEDs, but they are too low powered for anything other than week modeling in a pitch black room :)
