Technically, the UV LEDs can be installed in Hybrid Engine versions. The benefit is a lower product price, but there are downturns, such as lower power output and deteriorated on-off contrast in the image. In addition, larger variations in those parameters must be expected due to DMD batch variations. Last, but most importantly, Visitech will not be able to warrant the DMDs when used at an out-of-spec wavelength range, even though we have not experienced noticeable numbers of incidents.
