Glad that works for you. According to the Swhs review I linked to two of my posts up, there was a batch that had faulty electronics causing sort runtime. You might have one of those units. I'm not sure if mine, purchased late Nov 2011, exhibits this, since I didn't check runtime much before putting in the voltage converter.

I called Phillips, the service rep (Mary) said that the specs claim the light is suppose to run for 2 hours on high! I never knew that because neither the specs, nor the box that came with the light even mentions run time. So someone is suppose to contact me and let me know more about it.
Thanks for bringing that to my attention, I appreciate it. I'll let everyone know what they say and what they do about it. This will be a test of their customer service.
