Interesting. Having a hard time envisioning it as a modeling light inside a softbox or octo with a strobe. But interesting


You can only fish for so long before you gotta throw a stick of dynamite in the water. :cool:

I got a set of these to try.

100w LED E26 base candelabra bulbs (external link)

They're not terribly bright (still better than the LED on AD600), but they suit the purpose as a modeling lamp. But, being non-dimmable, they flicker in my Bowens monolights at all power levels.

They are also about 1/2" too long to fit in my 7 & 8" reflectors with grids attached. But they are just the ticket when I use my octoboxes, pattern projector or fresnel attachment.

The issue is still lumens. There isn't a compact Edison base LED that comes anywhere close to the lumens of a 150 or 250 watt halogen. The lumen modeling lights work much better in large modifiers, their effect with reflectors is more apparent, and they do a better job of allowing irises to contract.

Just picking a random 250W E26 base halogen for its specs, the output is stated as 4200 lumens.
A 150W halogen E26 base states 2650 lumen output.

The highest output E26 base LED I have seen is 20W actual '125W equivalent' and outputs 2000 lumens
