This 60mm COB glass lens is moulded from borosilicate glass 3.3 and delivers a tight 45 degree narrow beam for 30–150W COB LED engines. Each lens ships with a matched aluminium holder and silicone gasket, so luminaire makers can assemble a sealed optical module without extra tooling. The narrow beam is aimed at high mast, tunnel, port and stadium lighting where light must be thrown far down the road instead of spilled sideways.

High mast lighting for ports, airports and stadiums; tunnel and underpass luminaires; main road and highway street lights; industrial high bay and flood lights; solar street light heads that need an asymmetric long-throw beam.
Why choose the 60mm 45 degree version instead of a 50mm wide-angle lens?
The 60mm format carries a larger optical surface, so a 45 degree beam stays even for 30–150W engines mounted at 12–18m. Wide-angle 50mm lenses suit lower poles and broader area lighting; the two models are specified for different pole heights rather than as substitutes.
Is borosilicate glass better than PMMA for high-power COB LEDs?
For high-power engines the glass keeps its shape and clarity at temperatures where plastic optics soften, and it does not yellow under UV. PMMA remains a lower-cost choice for lower-power indoor fixtures.
Is the lens waterproof?
The lens itself is a solid glass body supplied with a silicone gasket and metal holder for a sealed fit. The final IP rating is set by the complete luminaire – housing, gasket compression and cable entry – so it should be validated on the finished fixture.
Can the beam angle or size be customized?
Yes. For OEM/ODM projects we can evaluate alternative angles, diameters and holder designs, subject to tooling cost and optical simulation.
Can I get samples before ordering?
Yes. Sample pieces are normally available for checking dimensions, light distribution and fit on your housing. Sample cost depends on model and project scope and is credited against bulk orders.
