Prismatic Pendant Lens 15° Beam Angle - 65mm Diameter

This prismatic pendant lens narrows the beam angle of compatible pendant fittings to 15°, creating a concentrated spotlight effect from what would otherwise be a wider flood of light. The 65mm diameter lens clips or screws into the lamp holder aperture of pendant track heads, mini pendants, and adjustable downlight pendants, redirecting the light output into a tightly focused cone suitable for accent lighting, artwork illumination, or product display.

Designed for both residential and commercial applications, the lens suits gallery rail systems, retail track lighting, museum displays, and home accent lighting where a specific object or surface needs highlighting without spill onto surrounding areas. The 15° beam is tight enough to pick out a single painting on a wall, a sculpture on a plinth, or a product on a shelf without washing adjacent surfaces with unwanted light. Installation involves removing the existing diffuser or cover from the pendant fitting and replacing it with this lens, typically a push-fit or threaded connection depending on the fixture model.

The prismatic surface etched into the clear polycarbonate controls the refraction of light passing through it, bending the rays inward to create the narrow beam without the colour shift or hotspot issues of a simple aperture reducer. The material resists yellowing under heat from halogen and LED sources, maintaining clarity over the lens's working life. The 65mm outer diameter is a common fitting size for mini pendants and track heads from multiple manufacturers, though compatibility should be confirmed against the specific fixture's lens holder diameter before purchase.

What fixtures is this lens compatible with?

The 65mm diameter is a standard size for mini pendant fittings and track heads. Compatibility depends on the specific fixture's lens holder diameter — measure the aperture or check the manufacturer's accessory list before ordering.

Does the lens reduce light output?

Yes. Narrowing the beam from a typical 40-60° flood down to 15° concentrates the light into a smaller area, which increases intensity at the centre of the beam but reduces the total illuminated area. Some light is also absorbed by the prismatic surface, typically reducing overall output by 10-15%.

Can it be used with LED bulbs?

Yes. The polycarbonate material tolerates the lower operating temperatures of LED bulbs as well as the higher heat from halogen sources. It will not yellow or degrade under normal LED use.

How is the lens fitted?

Fitting method depends on the pendant fixture. Most mini pendants and track heads use either a push-fit bayonet connection or a threaded ring to secure accessory lenses. Remove the existing diffuser or cover, align the lens with the holder, and push or screw into place.
