Product Overview

What This Product Is And Who It Is For

The high output driver on board module: 54 x 72 mm carrying 40W, 50W or 60W into a 20 mm emitting area, on 120V or 230V with no external driver. This is the board for high bay, large spot and outdoor pendant fittings that need real output from a small source and have no space or appetite for a separate driver.

Key Benefits

Why Buyers Choose This Build

Up to 60W with no external driver, which is unusual at this power level

20 mm emitter keeps the source small enough for a deep reflector at high wattage

One board covers 120V and 230V, so a fitting ships to both markets unchanged

0.95 power factor and 100 lm/W held across all three wattages

Application

Where It Fits And What It Fixes

Who It Is For

High bay and large spot light manufacturers
Outdoor and industrial pendant makers
OEM brands consolidating 120V and 230V versions

Problems It Solves

High output fittings where the driver box dictates the size of the housing
Large spot and high bay optics that need a compact source at 40W and above
Ranges duplicated across two mains voltages

Application Scenarios

Downlights
Ceiling lights
Spot lights
Pendant lights
High bay fittings

Comparison

How It Compares With Other Products In The Range

Compared With AC Module Standard DOB 40 x 36 mm

The smaller DOB board covers 5W and 10W with a 10 mm emitter

Compared With COB Flood Light 400W IP66

A finished outdoor luminaire rather than a board for a fitting maker

Use Guide

Specifying And Installing It Correctly

Design the heatsink for the full 60W even if the first build is 40W, so one housing covers the range
Keep the emitter at the reflector focal point, as the 20 mm source is what sets the beam quality
Do not run the board without the heatsink attached, even for a bench test
