I'm doing weddings and I've been looking all over for a good light to put on my DVX100. Somthing that is not too heavy and that has a battery back. I will be getting close at times so a soft filter may be needed.

I've been renting one but it's very heavy and bulky.

What are you guys using?

I'm using a frezzi mini fill but it is on the heavy side especially with the soft box on the front. The DVX isn't bad in low light but if you shoot on a tripod at the reception you'll need at least 35 watts (without diffusion). The softbox is nice but is useless beyond 10 feet and that's at 100 watts. I only use it for handheld work. Frezzi also makes a micro fill that works at 35 watts max but still requires a battery belt. It's half the weight of the mini fill however. I've been hearing a lot about the PAG light but it requires the use of a proprietary battery pack which means you're SOL if it craps out on you.
I've been tempted to buy the the Sony 20 watt light that uses their Li-ON batteries...

I know this isnt what you really are looking for.. but I am in the process of making my own super LED light that runs of a standard DVX100 battery (for more than 16 hours :) .. check out the prototype here:

Is there problems that can occur with high wattage on board lights like 50 or 100 watts? I tried a small consumer light that was 10 watts but only provided 15 minutes illumination time. Located a Bescor 50 watt light with B&H that has a separate battery pack plus barn doors (should get about an hour or less illumination). I am curious on the weight of the light plus the heat that will be generated. Could there be potential for problems from the heat from the on camera light and weight? Any experience with this?
