Application Examples
- Commercial corridors and lobbies requiring high-lumen output and Title 24 compliance.
- Residential great rooms and kitchens needing IC Air-Tight recessed lighting.
- Hospitals, schools, and offices standardizing on 0–10V dimming control.
Installation Tips
- Verify ceiling cut-out at 6-3/8"; ensure joists allow bar hanger adjustment.
- Set bar hangers parallel or rotate 90° to the J-box as needed; use the “L” foot to align to joist bottom.
- Choose the correct Cobalt HL reflector (1500lm 22W or 2000lm 28W); note NLCB2-656 is 22W only.
- For emergency egress, order housing /PEM and pair with NEPK-07LEDUNV remote battery kit.
- Maintain wet-location compliance by using designated reflectors and following gasket instructions.
Frequently Asked Questions
Q: Is NHICCB-615LE4 IC-rated and Air-Tight?
A: Yes. It’s IC for direct contact with insulation and factory-gasketed for Air-Tight (<2 CFM) performance.
Q: What voltages and dimming methods are supported?
A: 120/277V with Triac, ELV, or 0–10V dimming for broad control compatibility.
Q: Which reflectors are compatible?
A: Cobalt High Lumen 6" series: NLCB2-651, -652, -653, and -656 (note: -656 is 1500lm/22W only).
Q: Can I use this in wet locations?
A: Yes, when paired with designated reflectors that carry the wet-location listing.
Q: Does this include an emergency battery?
A: No. Order the housing with /PEM pre-wire and add NEPK-07LEDUNV remote battery separately.
Q: What are the key cut-out and housing dimensions?
A: 6-3/8" ceiling cut-out; approx. 12-3/4" length and 7-1/8" height.
Q: Are there restrictions with spray foam insulation?
A: Yes. IC housings are not for direct contact with spray foam insulation.
Q: How many knockouts are on the J-box?
A: Five 1/2" and two 3/4" knockouts, plus four Romex pry-outs with snap-on covers.
