The PMW Solar LED Streetlight (SLA-2IN1 Series) 150W - SLA150 is a commercial-grade, eco-friendly outdoor lighting solution designed for Malaysian roads, highways, and industrial estates. Featuring a powerful 22,332 lumens output, a high-efficiency 270W Monocrystalline solar panel, and a long-lasting 25.6V 120AH LiFePO4 battery, this two-in-one solar lighting system delivers reliable, continuous illumination even during periods of heavy rain. Equipped with 2 days of autonomy and intelligent preset dimming controls, the PMW SLA150 ensures maximum energy conservation, zero electricity costs, and an extended operational lifespan of up to 50,000 hours. Rated IP66 waterproof, it withstands harsh tropical environments, making it ideal for municipal, commercial, and rural infrastructure projects.
 

The PMW SLA150 Solar LED Street Light combines advanced solar panel design, ultra-bright LED chips, and premium battery storage into a heavy-duty, weather-resistant luminaire. Engineerd specifically for high-pole applications requiring a mounting height of 8m to 12m and pole distances of 25m to 35m, it provides uniform light distribution across wide roadways, industrial complexes, highway intersections, parking lots, residential streets, and public parks throughout Malaysia.

Key Technical Features & Performance

• Ultra-Bright 22,332 Lumens Output: Delivering high luminous efficacy at 150W power, providing clear visibility with warm-to-neutral color temperature options (3000K to 4000K) and a Color Rendering Index (CRI RA70).
• Monocrystalline Solar Panel (270W - 36V): Premium mono PV cells guarantee maximum solar energy conversion rates, ensuring full battery recharge even under cloudy or overcast conditions in Malaysia.
• Industrial LiFePO4 Battery (25.6V 120AH): Uses Lithium Iron Phosphate chemistry, offering superior thermal stability, extended cycle life, and high discharge depth compared to standard lithium batteries.
• Smart 3-Step Preset Dimming System: Features an automated power-management system designed to prolong nighttime battery runtime:

1. Hours 1–4: 100% full brightness during peak traffic.
2. Hours 5–6: 60% brightness as traffic slows down.
3. Hours 7–12: 40% energy-saving brightness until dawn.

• 2-Day Rainy Autonomy Backup: Built-in power management keeps the light fully functional for up to 2 continuous days during rainy or monsoon seasons without requiring additional grid power.
• Weatherproof & Heavy-Duty (IP66 Rating): Fully sealed against dust, heavy tropical rainfall, and extreme operating temperatures ranging from -20°C to +60°C.
• Flexible Dual Input Capability: Supports off-grid solar powering alongside standard AC grid integration (220VAC–240VAC, 50/60Hz) for hybrid deployment projects.

Q1: How long does the battery last on the PMW 150W Solar LED Street Light during rainy days?
A: The PMW SLA150 includes a 2-day autonomy feature powered by a 25.6V 120AH LiFePO4 battery, enabling it to provide full night illumination for up to 2 consecutive days without direct sunlight.

Q2: What is the recommended mounting height for a 150W solar LED street light?
A: The optimal mounting height for the PMW SLA150 150W street light is 8 to 12 meters, with an ideal pole spacing distance of 25 to 35 meters for uniform light spread.

Q3: What preset dimming mode does the PMW SLA150 solar light use? ​​​​​​​
A: The light operates on an automatic 12-hour energy-saving schedule: 100% output for the first 4 hours, 60% output for the next 2 hours, and 40% output for the remaining 6 hours.

Q4: Is the PMW SLA-2IN1 solar street light suitable for Malaysian weather?
A: Yes, it is IP66 waterproof rated and built with a high-capacity 270W monocrystalline panel designed to perform reliably under high heat and tropical rain conditions (-20°C to +60°C).

Q5: What is the lifespan of the battery and LED engine in the PMW SLA150?
A: The PMW SLA150 system features an LED lifespan of up to 50,000 hours, paired with a long-life LiFePO4 battery designed for years of maintenance-free operation.

Q6: What is the brightness output of the PMW SLA150 solar street light? ​​​​​​​
A: It produces 22,332 lumens of high-efficacy illumination with warmth options ranging between 3000K (Warm White) and 4000K (Cool White).

Q7: What is the difference between an integrated 2-in-1 and 3-in-1 solar street light?
A: A 2-in-1 solar street light system pairs the battery and LED luminaire inside the main body while using an adjustable, high-wattage external solar panel (270W) for optimal sun tracking and efficiency.

Q8: Why are LiFePO4 batteries better for commercial solar street lights in Malaysia?
​​​​​​​A: LiFePO4 (Lithium Iron Phosphate) batteries offer superior heat resistance, longer cycle life, and safer operation compared to traditional lead-acid or standard lithium-ion batteries in hot climates.

Q9: Where can I buy commercial-grade PMW solar street lights in Malaysia?​​​​​​
A: PMW solar street lights are available through authorized industrial lighting distributors and suppliers in Malaysia for municipal, highway, commercial, and residential projects.
