if you step up to white lightning they can handle more.

You could try to find a more efficient 150W bulb, but I don't know if there is one. For what reason do you need a brighter model lamp? ( I ask, as there may be work arounds)

As can Einstein.

Right now in the studio, I use two 800's side by side at full power on modeling or constant light. I like the look of this type of light rather than a low flash, as I want to shoot at 1.4 or 2.8. I would rather have the flexibility to use only one light that I can have more power with, so i can have it a little further from the subject.

Even one 1600, is not powerful enough. I hope that explained it.

Your're using ABs as lamps, no?
If so, it would be much easier to buy some $20 Smith-Victor constant light heads and mount them to your stands. You can put whatever bulb you want in them.

Ok, i think i understand. 1 B1600 model lamp will equal 1 B800 model lamp, which equals 1 B400 model lamp, so the lack of difference is not surprising. Einstein, WL, and Zeus all use 250W bulbs, just shy of 2x 150W that are in the Bees. A B400 has a minimum power roughly equal to the 300W (2x 150W) lights, exposed for 1/10, Einstein will be roughly equal to the same lights, but exposed for 1/20. B800's will be the roughly same as 1/5 of a second.

You can cut the flash power by the use of Neutral Density gels, which is a far less expensive option than new lights, as well, there is better action stopping from using the flash vs. a continuous source. Plus it is easier to mount and control 1 light rather than 2. We offer ND gels to fit the 7" reflectors, but you can get larger ones to fit larger modifiers as well.

Between 20 and 60 years of age, the eye's ability to distinguish contrast diminishes two-and-a-half times. You need brighter light the older you get and I'm getting close to the top end.
