Radius SafeZone LED Downlight
Tested to UL 263 and ASTM E119.
A slim, IC-rated downlight for rated ceiling assemblies. The RSZ series comes in 3, 4, 6 and 8 in at 120 V and dims to 10 % on TRIAC and ELV. The R2SZ series comes in 4 and 6 in at 120–277 V and dims over 0–10V. Both are air-tight to ASTM E283, wet location rated, and switch between five CCTs, CRI 90+. Order by series and size; the T-grid kit and the emergency J-box are each their own line.
