The unit for LAMP HOURS and DEVICE hours is, as Scott has indicated, in hours. On our products we actually keep track of such timings in increments of 10minutes, so that if the product is on for two 50 minute sessions, followed by a further 20 minutes, it will eventually show as having been on for 2 hours and not 0 hours.

Clearly such behaviour is dependent on a number of other factors, such as the provision of non-volatile storage and the number of times you can legally write to it over an extended period of time.
