To answer a potential buyer's question, Lumens versus effective Lumens towards your subject is quite complicated, the biggest factor being the shape and reflectence of the reflector you use. A simple wattage caculation would put this at around 4,000 lumens but you could focus this light by using a parabolic reflector, either the cheap ones from a hardware store, the larger cloth soft boxes without the diffusion cloth, etc. Just buy it and try it. Experimentation is half of the fun of photography! Be sure to adjust your camera's white balance manually if you don't like the auto white balance colors.
These will not fit in older Smith Victor (yellow)lamp reflectors so I was not able to use them.
Shipping was very fast. Sales person helped out greatly suggesting other item as substitute for OOS item same price. Local shops had this identical item/brand selling at $35-$40ea I forgot what I paid Adorama, but was somewhere about $6.95. They work just fine and the item got here the next day!!!
Great supplemental daylight source when used with the inexpensive ($ 15) clamp on reflectors from a hardware store. Be sure to manually adjust your white balance, as with any light source. I would also suggest using masking or gaffer's tape to secure the clamps. By only using 20% of the electricity of incandescent lights, they run cooler and won't overload your electrical circuits. All CFL bulbs are fragile so use care to avoid dropping them.
