Each lamp is made up of 64 bright light emitting diodes that are rated for over 20,000 hours of use. These LED bulbs are daylight-balanced and include a removable tungsten gel cap. They are able to render accurate skin tones with a 95 CRI rating.
The LED bulb can be changed from daylight to warm tungsten lights with the included tungsten gel cap. The durable plastic cap snaps directly onto the LED lamp.
I bought this lamp to use along with an LED panel for product photography. High color fidelity (CRI) was a priority. In the past, I have had to use CC gels with some LED sources to get the results I needed. This lamp exceeded my expectations for both brightness and color accuracy. I measured (to the degree I could) a color temperature of 5200K with no noticeable color artifacts -- an excellent match to my panel light. As for the intensity, I measured approximately 1200 lux at 1 meter which was sufficient to use it with light modifiers for a fill light. Fan noise was noticeable but not a problem for my applications. I consider it to be very useful and a bargain.
