Maybe it is the type of bulb? Are you trying to find LED tube bulbs to retrofit old fluorescent fixtures?

My Cree A21 (traditional incandescents looking) bulbs are 1700 lumens / 15 watts = 113 lumens per watt

EDIT: It might be color too. The "Soft White 2700K" version of my bulbs are only 100 lumens per watt.
