Sony HVL-20DX Camcorder Light

This is a Sony HVL-20DX Camcorder Light.  I bought this for use with my camcorder but then found my camcorder does not use the same kind of mount.  As a result I have not been able to use this.  when I realized this I didn't even both to buy a battery for it.  I have no way to test this to confirm its working since I don't have a Sony Battery for it, however I did remove both bulbs and test them, and both bulbs were working great.  This device uses NP-55 / NP-55H / NP-66H / NP-77 / NP-77H / NP-77HD batteries.  This device is supposed to only work with these batteries.  The unit has two settings 1 bulb and 2 bulb.  Giving you 10 watts of light or 20 watts of light.  Overall the unit is in excellent shape, however since I don't have any of these batteries I have no way to test the unit to be 100% its working.
