I wish to get an on camera light to put atop my XL1.

Should I go a 20W light or a 50W light?

Any suggestions for good kits?

I would definately go for 20w, as a long time news shooter lights will kill your battery in a hurry. I was using nice big anton bauer batteries and still had to be very cautious with the light. On camera lights really aren't good if you have any other choice to use. I would often times point mine almost straight up since they are so hard of a light.

35 watts with diffusion has been the magic number for us. Make sure the light you get has a dimmer.

Hey Mark

I reckon the dud who suggested getting a light with is a dimmer is spot on

Duff.

I've narrowed it down to the paglight C6 Portable lighting kit (20W) with own lightweight battery kit see http://www.videoguys.com.au/scripts/prodView.asp?idproduct=1433

or the videoguys kit that takes either 50W or 100W globes seehttp://www.videoguys.com.au/scripts/prodView.asp?idproduct=1433 it has it's own (bulky) battery

If people are suggesting using a globe less than 50 W, the first option, the lightweight C6 is probably my best bet.

Anyone have a C6? Recommend it?

You didn't mention your subject matter, however unless you are shooting outdoors at night, with no AC outlets, I strongly encourage you not to put 50-100 watts of blinding light on top of your XL1. In most cases, 20w is more than enough for the XL1 to work with (at short distances). If you need more power, it should come from other sources, such as a 500 watter bounced off a white ceiling/wall. Besides the considerable power draw mentioned earlier, having a powerful spotlight just a few inches above the lens creates the same cheap-looking results that a built-in flash on a consumer still camera does. Most people don't react well to having a blinding light pointed at them. At the very least, expect a lot of squinting, hand shielding and possibly even some violent confrontations (I've seen a few).

Frezzi dimmer mini-fill with soft box. It accepts lamps from 20w to 100w.

If you do go with Frezzi, don't get the shoe mount pictured. They make a better (more secure) one. It has a locking ring instead of that weird screw.

Here's a setup for the XL series.
