This is a dedicated 10° interchangeable lens for the Nanlite PJ-FMM Projection Attachment with FM Mount (which is sold separately). This lens provides a narrow beam with a long projection distance and incredibly bright output when used with a Forza 60C, 60B II, 60 II, 150B, FS-60B, FC-60B, or FC-120B LED Spotlight. It's covered by a 2-year warranty that extends to 3 years with online registration, and it's stocked, supported, and serviced by our responsive team in the USA. LONG THROW: Although this lens is relatively compact and lightweight, it does a remarkable job of throwing light an incredibly long distance, particularly when used with more powerful FM-Mount fixtures like the Forza 150B and FC-120B LED Spotlights. MORE LIGHT OUTPUT: This 10 degree lens provides a great concentration of the light, resulting in dramatically increased output in a narrow beam. HEAT DISSIPATING: The lens and required projection attachment feature a durable nylon construction that both stands up to the rigors of production work, and quickly dissipates heat so you can handle them without worry. EASY SWAP: Removing the current projector lens and swapping it for another is accomplished by removing a single screw. It only takes a few seconds and doesn't require any tools. CASE INCLUDED: A gel frame and a soft case with a drawstring closure are included. MADE AT NANLITE: We design, build, and test every product in our own facility.
