A lens aims light, a diffuser spreads it. Beam angle, haze, transmission and LED pitch decide which one you need, and stacking both costs output.

Most extrusions ship at ±0.3 to ±0.5 mm. Where a tighter band earns its cost, which four dimensions deserve a callout, and how to write it into an RFQ.

First digit vs second digit, what the IP test involves, and why a gasket is only half the job. How to specify IP65, IP66 and IP67 extruded LED profiles.

UV, LED board heat and hidden regrind all push a diffuser’s yellow index up. See the ΔYI, transmission and QUV numbers worth writing into your next spec.

An executable 6-week schedule from drawing review to mass-production SPC, with the deliverables and show-stoppers to check at every gate.

A 20-30% quote spread usually comes from inconsistent scopes, not margins. Break down lighting-cover extrusion cost and the three hidden costs B2B buyers most often miss.

Why a higher transmittance number can push UGR above EN 12464-1 limits, and how to choose PC vs PMMA and prismatic vs opal diffusers by failure mode rather than by datasheet.

How to Develop a Custom LED Diffuser Profile Developing a diffuser profile is a measurement exercise, not a selection exercise. […]

Custom Linear Lighting Profile Manufacturing Linear lighting is the most demanding application for extrusion because length amplifies everything: a small […]

PC vs PMMA for LED Light Covers For light covers the PC-versus-PMMA decision is usually made by compliance rather than […]

How to Reduce Cost in Custom Lighting Extrusion Most of the cost of a custom lighting profile is committed before […]

What Information Should Be Included in a Lighting Profile Drawing? A die ready to fit the extruder. Every marked dimension […]
