Installation Tips
- Confirm voltage and control wiring for 0–10V dimming before energizing.
- For hard ceilings, use the RFK/W recessed kit; for surface installs, select DFK/W (or DDFK/W when using EM or motion sensor).
- Maintain clearance from spray foam insulation; fixture is IC contact-rated but not for direct spray foam contact.
- When adding the optional microwave sensor, adjust sensitivity/hold time per room use after power-on self-check.
- Observe local codes; de-energize circuit and verify support for fixture weight before mounting.
Frequently Asked Questions
Does this panel qualify for rebates?
Yes. It is DLC Listed, which commonly qualifies for utility rebate programs; check your local provider’s requirements.
Can I change color temperature after installation?
Yes. The fixture includes a field-selectable switch for 3000K, 3500K, or 4000K. It ships preset to 3000K.
