ENER-J 50W Slimline DOB LED Street Light — 6250 Lumens, 125 lm/W, Wide Voltage 175–400V, Pole Mount (F315)

Choosing the right wattage for a road or compound is about matching coverage to the space — not just going bigger. The ENER-J F315 sits at the practical midpoint of the Slimline DOB series: 50W, 6250 lumens, and 125 lm/W efficiency. It’s the natural choice when you need more coverage than a 36W provides but don’t need the full output of a 100W — and it’s built to perform reliably in real Indian conditions, including the wide voltage fluctuations that trip up lesser streetlights.

Why the F315 Hits the Right Balance for Medium-to-Large Spaces

• 6250 lumens at 50W — serious coverage for the wattage: At 125 lm/W, the F315 pulls significantly more light per watt than conventional streetlights. That means a wider, brighter pool of light for less electricity — and across a multi-light installation, the energy saving stacks up fast.
• Wide 175–400V input — built for Indian voltage: India’s grid doesn’t always deliver a stable 220V. The F315’s input range covers everything from 175V to 400V, handling dips and surges without flickering, tripping, or degrading. It keeps running consistently where voltage-sensitive lights fail.
• DOB technology — fewer components, longer life: With the driver chipset integrated directly onto the LED board, there’s no separate driver unit to fail. It’s the component that typically goes first in conventional streetlights — the F315 eliminates it entirely, resulting in better heat management and longer operational life.
• Built-in surge protection: The DOB design includes integral surge protection — guarding against voltage spikes during grid restoration after power cuts. No external protection device needed.
• 72 LEDs with high-efficiency nano reflector: Seventy-two LEDs spread across the slimline housing, directed by a grey nano reflector for precise, even distribution onto the road or compound surface. Minimal light wastage, maximum usable output.
• Ultra-slim die-cast aluminium housing: At 334 × 118 × 21mm, the F315 has a clean, professional profile. The die-cast aluminium body dissipates heat efficiently — keeping the LEDs running cooler, which directly extends lifespan and maintains lumen output over time.
• PF > 0.9 for grid-efficient operation: A high power factor draws clean, efficient current — important for larger compound installations and commercial premises where poor power factor can attract utility penalties.
• CRI > 80 for accurate visibility: Road markings, vehicles, people, and obstacles all appear with natural colour accuracy — important for safety in road and parking applications.
