Product Overview
What This Product Is And Who It Is For
A 500 x 24 mm tunable white board on 24V carrying 70 pieces of 2835 across a 2700K and a 5700K channel. All three part numbers share the same 20W draw, 400 mA current and 130 to 145 lm/W efficacy, and differ only in colour rendering grade, so a specifier can move from CRI 80 to CRI 98 without any change to the driver, the board size or the thermal design.
Key Benefits
Why Buyers Choose This Build
CRI 80, 90 and 98 on identical electrical and mechanical specifications
Efficacy stays at 130 to 145 lm/W across all three grades, with no penalty for choosing CRI 98
Dual channel 2700K and 5700K gives full warm to cool tuning from one board
500 x 24 mm suits shelf and display profiles as well as general linear fittings

Comparison
How It Compares With Other Products In The Range
Compared With DC Module Standard for Cooler Lighting
The cooler build runs at 38V with 140 to 560 mm lengths and a 6500K cool channel
Compared With DC Module Square Module Dual Color
A 260 x 260 mm square footprint for downlights and ceiling fittings rather than a linear board
Use Guide
Specifying And Installing It Correctly
- Specify the CRI grade at order stage, as the part number is the only difference between the three builds
- Drive both channels from a two output driver so the mix can be held under dimming
- Keep the board flat against the heatsink over the full 500 mm
