5050 LED Lens Reflector Collimator Pack - Multi Angle Optics for LED

In this review the 5050 LED Lens Reflector Collimator Pack is evaluated for makers, lighting hobbyists, and small-scale installers who work with 5050 SMD LEDs such as WS2812, APA102, WS2811 and SK6812. The biggest reason to consider this set is its range of beam angles and high optical transmittance, which together allow precise control of beam spread and improved uniformity compared with bare LEDs. The reviewer found the lenses helpful for reducing the yellow halo and for achieving consistent spot shape across arrays.

Key Features

• Multi-angle selection: Includes lenses in 10, 30, 60, 90, 120 and 140 degree profiles so users can tailor beam spread for tight spots or wide wash use.
• Compatibility: Sized for 5050 SMD LEDs so they fit common addressable LED types like WS2812, APA102, WS2811 and SK6812 and other 5050 format diodes.
• High transmittance: Made from transparent PMMA/PC with about 93% optical transmittance to preserve brightness while shaping the beam.
• Reduced artifacts: The convex lens profile helps overcome yellow halo and softens lighting for more uniform spots without black holes or harsh shadows.
• Small footprint: Compact approx. 10x8x6mm size keeps the lens unobtrusive on densely populated PCBs and LED strips.

Who It's For

This pack is best for electronics hobbyists, DIY stage or accent lighting builders, and small studio riggers who already use 5050 SMD LEDs and need a practical way to change beam angles without swapping LEDs. It is especially useful when creating arrays where consistent spot shape and reduced halo are important.

Those who should look elsewhere include users requiring sealed optics for outdoor use or high-temperature industrial fixtures, since these lenses are general-purpose PMMA/PC optics intended for typical indoor or protected installations rather than weatherproof housings.

Pros & Cons

Pros

• Wide range of included beam angles gives flexibility for many lighting designs.
• High optical transmittance preserves output while improving uniformity of the LED spot.
• Compact size fits standard 5050 LED packages and keeps densely populated boards tidy.
• Convex design reduces yellow halo and unwanted shadows for cleaner light.

Cons

• Material is PMMA/PC and the lenses are not described as weatherproof, so they may not suit unprotected outdoor installations.
• Pack handling and alignment on small PCB pads can be fiddly without tweezers or a fixture.

Our Verdict

The 5050 LED Lens Reflector Collimator Pack is a practical, cost-effective way to shape light from popular 5050 SMD LEDs and reduce halo and uneven spots. For hobbyists and small-scale installers who need multiple beam angles and high transmittance optics, this set offers clear value; those needing rugged, weatherproof optics should consider specialty housings instead.

Frequently Asked Questions

Will these fit WS2812 addressable LEDs?
Yes, they are sized for 5050 SMD LEDs and are compatible with WS2812, APA102, WS2811, SK6812 and other 5050 format diodes.

Do these lenses reduce brightness?
The lenses have about 93% transmittance, so they preserve most of the LED output while improving beam uniformity and reducing halo.

Are these suitable for outdoor fixtures?
They are general PMMA/PC optics and are not specified as weatherproof, so use them in protected or indoor installations or add appropriate sealing for outdoor use.
