Heat Resistant Borosilicate Glass LED Street Light Retrofit Kit – 75×135 Degree Beam 95% Transmittance

A retrofit optical kit built around one problem that ends most plastic-lens projects: heat. The 106.6 × 32.86mm borosilicate glass lens sits directly over the LED array inside a sealed housing, where temperatures climb past the point that PMMA and PC optics begin to yellow, sag or crack. The kit arrives complete – glass lens, silicone gasket, metal holder, reflector, multichip LED and driver – so a road light can be re-qualified with a single part number instead of five suppliers.

• Borosilicate glass heat resistance – low thermal expansion and a softening point far above PMMA allow the lens to sit close to a 150W-class LED array inside a sealed tunnel or street luminaire, where a plastic optic would deform within months. No yellowing, no beam drift, no re-lamping of optics during the fixture's service life.
• 95% transmittance, low glare – the plano-convex body passes 95% of emitted light, so a given illuminance is reached at lower drive current. The polished surface also keeps scattered light low, cutting the veiling glare that shows up in roadside photometric complaints.
• 75×135 degree asymmetric road lighting – the elliptical distribution throws light along the road axis and spreads it across lanes and shoulders at once, raising uniformity (U0) without adding pole height. Fewer dark patches between poles means fewer fixtures per kilometre.

Why specify a glass lens instead of PMMA?
Inside a sealed street or tunnel luminaire the optic runs continuously at elevated temperature and under UV. Borosilicate glass keeps its shape and clarity there, while plastic optics lose transmittance and can deform. The 95% figure on this lens is a service-life figure, not a first-day figure.

What does the 75×135 degree beam do for a road layout?
The narrow axis runs along the carriageway to give reach between poles; the wide axis covers lanes, shoulders and pedestrian edges. The result is more even illuminance with a lower mounting height, and less light spilling onto adjacent property.

Can I order samples for testing?
Yes. Sample orders are welcome and mixed samples are acceptable, usually shipped in 3–5 working days.

What is the lead time for mass production?
7–10 working days after deposit for standard configurations; longer schedules apply to customised or large-volume orders.

Can I print my logo?
Yes. Please confirm the artwork before production and approve it against a sample.

What warranty applies?
2 years. Defective units are replaced free of charge against photographic evidence.
