On the bulbs themselves? They were already in units
Cool thsnksI'd probably replace the bulbs before putting them to use myself, but if you only have the bulb, on one of the ends there should be the make, wattage and I believe the spectrum (5000k for example). Just google the manufacturer and bulb wattage and you should be able to find the amount of lumens.
