20W 5-Color Linear LED Track Light GDSD12B-3
GDSD12B-3 is the high output head in the range, a 20W linear bar that delivers 1200 lumens with CRI above 90. The 18.9 inch body spreads light along a shelf or a counter instead of dropping a single pool, which is why it is chosen for long display runs and open plan commercial spaces. It is ETL certified and available in black and white.

Compared With the Alternatives
| Cylinder track heads | The linear body lights a long shelf evenly while a cylinder head drops a single beam |
|---|---|
| XL04 13.5W head | GDSD12B-3 delivers 1200 lumens against 930 lumens, for areas that need more coverage from fewer fixtures |
| Non certified track heads | ETL certification supports commercial projects that require listed fixtures |
Use Guide
- Confirm the run uses H-type track before ordering the linear head
- Switch off the circuit and glide the head onto the rail
- Select the colour temperature on the fixture
- Set the aim within 90 degrees vertical and 350 degrees horizontal along the shelf
- Use a TRIAC dimmer for 10 to 100 percent output
- Allow the luminaire to cool at least 5 minutes after switch off before handling
