Frequently Asked Questions
Q: What does UGR<1% mean for my project and how is it achieved?
Unified Glare Rating (UGR) measures discomfort glare on a scale from 5 (unnoticeable) to 40+ (painful). A rating of <1% is essentially glare-free— pedestrians perceive the illuminated area without ever seeing a bright light source. THEMIS achieves this through a precision-engineered optical lens array that directs all light downward within a controlled cutoff angle, eliminating upward light spill and horizontal glare. For municipalities and eco-resorts, this means: (1) compliance with dark sky ordinances in sensitive areas, (2) zero impact on nocturnal wildlife navigation and breeding patterns, and (3) more comfortable pedestrian experience without the harsh "glare halo" common on standard post-top luminaires.
Q: How does THEMIS achieve 5 days of autonomy with a 154Wh battery?
Three factors combine for extended autonomy: (1) 190lm/W system efficacy — THEMIS produces the same 2,800 lumens while consuming significantly less energy than standard 100-130lm/W post-top lights, (2) MPPT charge controller with 97% conversion efficiency — extracts nearly all available energy from the 38W panel vs typical 85-90% for PWM controllers, and (3) programmable intensity profiles — the system can be configured to reduce brightness during low-traffic hours (e.g., 100% dusk-10pm, 50% 10pm-dawn), extending runtime to 5+ nights from a single full charge. This is critical for regions with extended rainy seasons where 2-3 overcast days are common.
Q: Can THEMIS be customized for municipal tender specifications?
Yes. THEMIS features a fully programmable MPPT controller supporting custom light intensity schedules and duration profiles per municipal requirements. Configurable parameters include: dimming curve (any combination of brightness levels across the night), CCT selection (dual CCT options for amber/warm corridors vs standard pathways), adaptive brightness based on battery state-of-charge, and motion sensor triggering (optional). E-Able Power provides complimentary DIALux lighting simulation with iso-lux maps and pole layout for tender submission documentation.

Q: Where is THEMIS most commonly deployed, and what maintenance is required?
THEMIS is purpose-built for dark sky communities, eco-resorts, national parks, coastal boardwalks, wildlife corridors, and municipal pedestrian pathways where light pollution regulations and wildlife protection are project requirements. The fixture is fully self-contained — no trenching, no cabling, no grid connection. Maintenance: annual cleaning of the solar panel surface (glass cleaner + soft cloth), visual inspection of the optical lens for debris, and BMS SoH check. The LiFePO4 battery requires no water, no electrolyte, and no equalization — rated for 6,000+ cycles (10+ years nightly operation). IP65-rated housing protects against rain, dust, and humidity. The LED array is rated >100,000 hours (L70) — exceeding 25 years in nightly use. 5-year global warranty.
