When a bond joint needs the highest UV flux a single lamp can deliver, or the lamp head needs to sit further from the part than a standard cable allows, the Incure LLG-1P-8 is built to cover both problems without compromise on either.
The Widest Core Collects the Most Light
Core cross-sectional area governs how much UV energy a liquid lightguide collects from its source, and the LLG-1P-8’s 8 mm core delivers the largest area in the single-pole range at 50.3 mm² — 2.6× the LLG-1P-5’s 19.6 mm² and 7.1× the LLG-1P-3’s 7.1 mm². On wide, thick, or fast-cycling bond joints where the narrower cores in the same range under-dose the adhesive, the LLG-1P-8 delivers the maximum energy available from the lamp without changing the lamp head or extending exposure time. More core area simply means more light collected per cycle — a mechanical property of the guide, not a lamp setting.
The Longest Cable Run Without a Transmission Penalty
At up to 6,200 mm, the LLG-1P-8 reaches distances neither the LLG-1P-5 (3,000 mm maximum) nor the LLG-1P-3 (2,000 mm maximum) can cover — seven length options in total, the widest range of any configuration in the LLG line. That reach matters whenever the lamp controller needs to sit away from a heat-sensitive assembly area, or whenever fixture geometry places the bond point deep inside an enclosure that a shorter cable simply can’t reach without rerouting the line.
Liquid lightguide construction holds full transmission across that entire length range — the same up-to-5-W output and 300 nm minimum wavelength at 500 mm as at 6,200 mm. Unlike fiber optic bundles, which lose transmission per meter on longer runs, the liquid waveguide delivers an identical cure footprint regardless of cable length. Length selection becomes purely a fixture-geometry decision, never a performance trade-off.
That matters directly when a facility layout changes — relocating a lamp controller to a different position on the line, or adding a new enclosure around an existing station, doesn’t force a re-qualification of cure dose or exposure time the way it would with a lossy transmission medium. Cable length can be resized to match the new layout without re-running process validation on the cure recipe itself.

Direct Terminator Compatibility at Ø8mm
The LLG-1P-8 pairs directly with the Ø8mm LGT-Series terminators — the LGT-90-8 for perpendicular bond access and the LGT-60-8 for oblique reach into recessed or angled cavities — with no coupling loss at the Ø8mm interface. For facilities already running Ø8mm equipment, that terminator compatibility extends the guide’s reach into geometrically constrained bond faces without introducing an adapter interface.
Application Fit
The 8 mm core suits applications defined by either constraint independently, or both together: bond joints too wide or too thick for the mid-range 5 mm core to dose adequately in one cycle, and fixture layouts where the lamp-to-part distance exceeds what shorter guides can cover. Fast-cycling production lines that need maximum energy delivered per trigger event without extending dwell time benefit particularly, since more core area means the same exposure duration delivers more total dose. As with every guide in the single-pole LLG range, it’s driven by mercury arc, xenon, or halogen spot curing lamps and is not compatible with UV LED sources.
Choosing the 8 mm core over the 5 mm option is worth revisiting whenever a process is running near maximum trigger duration to hit target dose — if exposure time is already stretched to compensate for a lower-flux guide, moving to the LLG-1P-8 often recovers cycle time directly rather than requiring a lamp upgrade. Operating temperature is rated −5°C to +35°C, the same range as the rest of the single-pole family, a spec worth checking against the ambient conditions wherever the lamp head itself is placed.
Positioning Within the Single-Pole Range
Against its two single-pole siblings, the LLG-1P-8 sits at the high end on both flux and reach. The LLG-1P-3 offers the tightest, most contained cure spot and the shortest available cable at 500 mm, suited to compact fixtures where over-irradiating adjacent components is the concern. The LLG-1P-5 sits in the middle, pairing directly with Ø5mm terminators and covering the majority of standard joint sizes at moderate reach. Multi-point configurations — the LLG-2P-3, LLG-3P-3, and LLG-4P-3 — solve a categorically different problem: simultaneous multi-point cure from one lamp rather than maximizing flux or reach at a single point.
For UV LED spot curing, the Incure L9000 lightguide series is the compatible system rather than any liquid lightguide configuration. See the full lightguide selection guide for a complete range comparison, pair the LLG-1P-8 with an Incure S20 arc spot lamp for maximum-flux mercury arc curing, and see the LS217 lightguide simulator for establishing a transmittance baseline once a guide configuration is in service.
