these were recently a very good price over on ebay so i decided to snag one. well, i should have grabbed a few while i had the chance because they cost 2.5x now. since i was only able to snag the one, im using it in my 2x4 and its perfect. full coverage. the size and shape are spot on for a 2x4. if you come across one on sale for $150usd or less, i HIGHLY recommend this light.
