The Alzo 1146504 is a Set of 4, 45 Watt Photo CFL Fluorescent Light Bulbs. It is equivalent to 150 watts of Tungsten light. The bulb is used in Alzo 600 "Cool Lites" and Alzo 100 Light kits. These bulbs are larger than the Alzo 27 watt bulbs and will not fit in the Alzo 300 light fixture.

Other than being somewhat fragile (as is normal for these types of CFLs), I like to use these lower-wattage units in multiples (e.g., a five-socket adapter in a softbox) which allows me to 'fine tune' the lighting to my immediate needs. To minimize the occasional slight greenish tinge I use a fluorescent light filter.
