SmallRig Ra-F150 Focusing Fresnel Lens for Led Monolights

What sets the Ra-F150 Focusing Fresnel Lens for Led Monolights apart is its innovative one-handed focus adjustment feature. This unique design eliminates the risk of hand burns and saves time by allowing users to adjust the focus simply by rotating a conveniently placed knob. This lens is equipped with a triple cooling system, a groundbreaking patented feature that includes a heat dissipation fan for active cooling. This system is further enhanced with heat sinks and heat dissipation holes, all working in unison to cool the device effectively and extend the lifespan of the light units. The Ra-F150 Focusing Fresnel Lens boasts a 13.2x light output, achieved by using high-transparency, high-temperature-resistant borosilicate glass. This glass undergoes a high-temperature lamination process, enhancing its heat resistance while simultaneously improving transparency and light transmittance.
