They carry the industry standard Jansjo light for $9.99. They are by far my and numerous other coin photographers go to lighting choice. I have found that the best diffuser for them are Coinsafe half dollar tubes. The main tube slips over the head of the light. The tubes are then moveable and you can aim them.
