Description
The Lumistar ME-LED luminaire is a compact stainless-steel sight-glass light for screw-type fittings (DIN 11851). It gives clean, low-heat LED illumination for pipelines, laboratory mixers, tanks and processing vessels in non-explosive areas. Full technical details from the official datasheet.
Why choose the Lumistar ME-LED?
- Designed for DIN 11851 screw fittings: fits DN65, DN80, DN100 and DN125 screw-type sight glass units.
- Low-power, low-heat LEDs: ME65/80: 12–24 V DC at 1.5 W (~104 lm); ME100/125: 24 V AC/DC at 2.0 W (~170 lm).
- Beam control: beam angles 26° or 33° provide focused illumination for inspection ports.
- Plant-ready: IP65 when correctly fitted; factory-fitted 3 m temperature-resistant cable (Lapptherm 105).

Installation summary
- Loosen the slotted cover nut on the screwed sight glass fitting.
- Lead the nut over the connecting cable and lamp housing; align the centring feature on the nut.
- Screw the nut tight against the welding adapter with the luminaire fitted. Verify sealing web on the ring seal.
- Observe polarity for DC wiring (brown = +, blue = −); green-yellow for earth when applicable.
- Do not connect power until the mechanical installation is complete. Test operation.
Applications
- Pipeline inspection and sight glass ports
- Laboratory mixers, small tanks and agitators
- Food processing and pharmaceutical plants (hygienic stainless steel construction)
FAQ (short)
- Q: Which ME-LED fits my DN 80 sight glass?
- A: Choose ME 80-LED for DN80 screw-type fittings (nut opening d8 = 94 mm). Confirm nut dimensions per DIN 11851.
- Q: Can I order a built-in pushbutton?
- A: Yes — ME-LED models can be supplied with or without a pushbutton. Specify at order.
