Replace Halogen Modeling Light with LED?

[SdeGat]

Many modeling lights are 150w fairly standard halogen bulbs (like the one in the middle below).

Has anyone replaced some of those with LED "bulbs"?

If so, any recommendation/advice?

Thanks.

The problem is trying to come anywhere close to matching luminescence. That's probably a 150 watt incandescent bulb putting out over 2,000 lumens. If that's a halogen bulb, it's putting out a bit more.

That's going to take about a 20-25 watt LED to compare. That's going to be a larger-than-normal LED bulb that will block a lot of the light from the flash tube. Its also likely to be non-dimmable, if that's something you do.

But try it and see if it works for you.

These are good points. I usually dim the halogen because of the heat but I could leave the LED at full power all the time given that they don't get very warm.

These 1600 lumen bulbs don't seem to be too big...

They're also not very powerful. LEDs become comparable at about 30 watts.

But give them a try.

Someone on another forum used an LED corn bulb and was pleased with the results. Not this model per se, but to give you an idea:

I really dislike halogen bulbs because these energy hogs really suck up power and are hot enough to char flesh. Also, they've been known to explode from fingerprint oil if someone is sloppy changing the bulb.

If you can, I would definitely find a LED replacement. I did this on my old Bogen and White Lightning strobes and they worked fine.

If you want to be able to dim the light, you need a dimmable LED that's compatible with the dimming circuit in your strobe. Not all combinations are compatible.

1600 lumen is comparable to 100 watts. The LED I referred to above are 15 watts and not the less powerful 6 watts (I think) that would not be very bright.

Ah! Very helpful. Thanks jlafferty.

Good point. I think I would just turn off the “proportional” feature of the strobe as I would not have to worry about heat.

That's unlikely to be much of an issue on the larger E27 bulbs that these LEDs would replace (typically 100-250 W, they have a secondary glass cover), yes certainly an issue for the 300+ stuff but these LEDs aren't much use as replacements there.

I can confirm the secondary glass cover on the halogen as this is what broke on my modeling light. The inner halogen is still working actually.

Somewhat bigger, I’ll have to see how it works now...
