I made a 5 watt LED head light. The LED mounts at eye brow level between the eyes. I would like to cool it with a heat pipe curved towards the back of the head. Has anyone made their own? What did you use inside (Acetone?) What did you use for a wick?

I would like to purchase an appliance that is unfortunately available only in the U.S.( U-line Wine Captain® Drawer Model 2175DWRWC) which means its 110 volts. I need to use it in Hongkong which uses 220 volts. I don't want to use converter or transformer because I think it would not be very energy efficient because the appliance would be use 24/7, 365 days. Any suggestion on how I can change my appliance from 110 volts to 220 volts. I already contacted the company and they don't want to custom made. Thank you
