Product Overview & Applications

The LAMPHILL Surface Mount LED Panel Light PP Series delivers high-efficiency illumination in a sleek 1x4ft (300x1200x39mm) rectangular profile. Powered by a 48W engine producing 100 lm/W, this surface-mounted fixture eliminates the need for recessed ceiling cutouts, making it an ideal upgrade for standard plaster, concrete, or grid ceilings. Featuring SIRIM certification and durable aluminium and iron construction in a clean matt white finish, it delivers stable performance across an AC175-265V input range.

Engineered with a wide 120° beam angle and a CRI >80, this 48W panel provides uniform, low-glare light distribution in two distinct color temperatures: 4000K Cool White for focused working environments and 6500K Daylight for high-clarity spaces. Its IP20 rating makes it specifically suited for dry, covered indoor installations across residential, commercial, and institutional projects.

• Office Spaces & Conference Rooms: Provides wide, even overhead light distribution across workstations and meeting areas to minimize eye fatigue.

• Retail Stores & Showrooms: Delivers color-accurate illumination (CRI >80) to accurately showcase merchandise and display shelves.

• Residential Living & Study Areas: Mounts directly to flat concrete or plaster ceilings in homes requiring bright, full-coverage ambient light without recessed cutouts.

Key Features

• High Efficacy & Energy Efficiency: Delivers 100 lm/W for an optimal balance between low power consumption (48W) and high lumen output.

• Surface Mount Design: Installs directly onto flat ceiling surfaces without requiring ceiling cutouts or complex recessed framing.

• Color Accuracy (CRI >80): High Color Rendering Index ensures colors appear natural and true under both 4000K and 6500K options.

• Wide Voltage Tolerance: Operating range of AC175-265V 50/60Hz protects against standard line voltage fluctuations for consistent light output.

• SIRIM Approved Quality: Complies with Malaysian safety and performance standards for trusted commercial and residential deployment.

Frequently Asked Questions

Q1: What is the difference between a 12W/18W downlight and this 48W LED panel light? A: A 12W or 18W downlight provides localized accent or small-room lighting, whereas this 48W 1x4ft panel produces a significantly higher overall lumen output designed to illuminate larger surface areas evenly from a single fixture.

Q2: Is this LAMPHILL PP Series LED panel light suitable for outdoor use or high-humidity areas? A: No. This light has an IP20 rating, which means it is designed strictly for dry indoor environments. It should not be installed outdoors or exposed to rain, splashing water, or high humidity.

Q3: Can this surface mount panel withstand monsoon weather or high-moisture tropical conditions? A: The IP20 rating limits this fixture to indoor, weather-protected areas only. For covered indoor tropical spaces, ensure it remains free from direct condensation and water ingress.

Q4: Does this LED panel light require an external driver or transformer for installation? A: The unit operates on standard AC175-265V mains supply (50/60Hz) and connects directly to standard building wiring without requiring additional external transformers.

Q5: How is this surface mount panel installed compared to a recessed panel? A: Unlike recessed panels that require cutting a 300x1200mm opening into the ceiling, this surface-mounted unit secures directly onto the ceiling surface using its mounting frame at a total profile height of 39mm.

Q6: What is the difference between the 4000K and 6500K model options? A: The PP312-4840M (4000K) produces a neutral Cool White light suitable for balanced task lighting, while the PP312-4865M (6500K) produces a bright, crisp Daylight output ideal for maximum visibility.

Q7: Is the brightness or color temperature adjustable on this fixture? A: No, the color temperature is fixed based on the selected model (PP312-4840M for 4000K or PP312-4865M for 6500K), and the light operates at a fixed 48W wattage output.

Q8: What ceiling materials can this 300x1200x39mm panel light be mounted on? A: It can be mounted directly onto flat concrete, plasterboard, gypsum board, or wooden ceiling surfaces using standard mounting fasteners.
