The PrimeTime Lighting GUS 51 LED Fresnel has a 60W power draw and an adjustable beam angle of 11-80°. It is available in either daylight or tungsten versions.

The GUS 51 is passively cooled so there is no fan. PrimeTime’s Therma-draw heat dispersion technology means that the light is cool to the touch and dead quiet.

It utilizes a 6.25″ Micro-Fresnel lens and the advanced optics are claimed to be able to provide an even wash of light, unlike any other LED Fresnel. There is less than a 2.8% decrease in brightness from the center to the outer edge. PrimeTime Lighting under-drives the diodes in all of their LED products to extend diode life and color balance consistency.

The GUS51 is backed by an impressive five-year warranty and it is handmade in the USA. The fixture is 100% machined, extruded, and made out of aluminum.

The light has physical dimensions of 8.5 x 8 x 10″ (LxWxH) / 21.59 x 20.32 x 25.4cm and it weighs in at 14lb / 6.35kg. This is certainly heavy for a 60W fresnel, but most of that weight is coming from the aluminum construction.
