Introduction
We conducted a real-world beam and throw comparison between two lights built on the same SFT60-65 LED , featuring two classic optical solutions:
X1S OP lens (throw-focused) and E04 TIR lens (flood-focused) .
Same emitter, totally different beam performance and use cases.
Test Data
X1S-OP (Long Throw Version)
Lume 1: Max 4500lm / 572m
Lume 10 Turbo: Max 5000lm / 591m
E04-TIR (Wide Flood Version)
Lume 1: Max 10000lm / 500m
Lume 10 Turbo: Max 11500lm / 529m
Beam Characteristic Differences
X1S OP Lens
Highly concentrated hotspot, minimal beam divergence
Higher candela and extreme long-throw performance
Piercing beam pillar for long-distance targeting.
Soft spill maintains basic peripheral visibility
Best for: Search & rescue, long-range spotting, cave exploration, outdoor recon
E04 TIR Lens
Uniform flat flood beam with zero harsh hot spot
Low glare, smooth transition, wide coverage
No dark corners on large-area surfaces
Comfortable for long-duration viewing
Best for: Night patrol, hiking, site inspection, campsite lighting, daily carry
Real Outdoor Performance
X1S OP : Outstanding long-distance penetration. Faraway terrain and cliff details are clearly visible with strong centered luminance.
E04 TIR : Full even illumination across the entire field, providing stable eye-friendly wide flood lighting for daily tasks.
Final Verdict
X1S OP = Pure long-distance search light (max 5000lm / 591m)
E04 TIR = All-round daily flood light (balanced & low-glare)
Same SFT60-65 LED core, different optical designs fully define two professional lighting styles for tactical outdoor and daily duty scenarios.
