Because there was some confusion about the differences between our LED lamps PHOTON and the YPSILON, here is a better comparison.

In the actual version of our PHOTON works the SST-50 LED with 4,3A (constant current driver).
In the new YPSILON is the same LED, but it works unregulated in direct drive mode. The max. current is limited to 5A. With increasing burning time, the current goes down. Because the efficiency of an LED increases with a decreasing performance, you will not notice any slowdown in brightness for the first hour of burning time. After this time the brighness goes down up to the end of burning time after 4 hours.
All values are in full power position!

Only the PHOTON gives the possibility of changing the reflector between a 10° spot, a 20° medium and a 80° video light.
The YPSILON is fitted with one of the both reflectors 10° spot or 20° medium (normal version is 10° spot).

The YPSILON is a low cost version of the PHOTON with some advantages.
