Do you stock obsolete industrial lighting?

Yes. Discontinued Banner WLS27 first generations, retired Patlite LWS codes, end-of-life Stahl ExLED, and earlier Werma signal lighting are sourced through our supplier network.

What color temperature should I use?

For general work areas: 4000 K neutral. For inspection or color-critical work: 5000–6500 K daylight (best color discrimination). For comfort areas: 3000 K warm. Match the existing fixtures in the area to avoid color-mismatch shadows.

Can the light be controlled from my PLC?

Yes for most modern industrial LED fixtures. 24 VDC fixtures switch directly from PLC outputs; IO-Link fixtures allow dimming and color control. Specify the control method needed when ordering.

Are explosion-proof certifications preserved on surplus fixtures?

Yes — the OEM hazardous-area certification (Class I Div 1/2, ATEX, IECEx) is the property of the fixture when manufactured. Surplus units retain certification provided they have not been physically modified.

What's the typical LED fixture lifespan?

50,000+ hours for the LED source itself. The driver (electronic component) is usually the first failure mode, with typical life 30,000–50,000 hours depending on operating temperature. Industrial-rated drivers extend life.

What is the warranty?

12-month functional warranty on the fixture. LED light output naturally declines over time (L70 = 70% output at end of rated life); declining output within the natural decay curve is not a warranty event.
