I was pleased to find the same sunlamps that NIH used in their vitamin D studies. The unit is pretty straightforward, although I sometimes have to turn the lamps in their sockets to get them to turn on.

Thank you so much for sharing with us! Please make sure that the labels on the bulbs are all facing straight forward. Once they are all correctly locked into the sockets, the unit should turn on right away. If you continue to have any technical difficulties, please give our office a call.
