Answer:
The PEL LED LTBL features a 22 SWG MS CRCA sheet metal housing finished in white epoxy polyester powder coating, chrome-plated reflectors, and clear molded ABS/polycarbonate diffusers. It uses a constant current charger with a red charging LED indicator that automatically transitions to trickle charge once the Li-ion rechargeable battery (they are not included) is replenished.
Designed for demanding commercial and industrial infrastructure, the Prolite PEL LED LTBL utilizes the following construction and charging systems:
- Enclosure Construction: Fabricated from 22 SWG mild steel cold-rolled close annealed (MS CRCA) sheet metal and treated with a protective white epoxy polyester powder coating.
- Optical Components: Chrome-plated directional reflectors paired with clear molded ABS/polycarbonate diffusers over the LED arrays.
- Charging Circuit: Constant current charging circuit with an initial 16 to 24 hour recharge cycle. Once the Li-ion rechargeable battery (they are not included) reaches capacity, the circuit automatically shifts into trickle charge to maintain readiness without overcharging.
- Visual Indicator: Front-mounted Red LED illuminates to confirm active mains charging.
- Deep-Discharge Cut-Off: Automatically cuts off battery power (they are not included) at the end of the backup duration to protect internal circuitry and cell life.
