UL1971 Haz Loc Synchronized LED Light


The D2x1BLD2-H utilizes an array of high power Cree® LED’s, orientated to optimize visibility in any direction. Multiple D2xB1LD2-H units will auto-synchronize when powered from the same power source removing the need for any additional sync modules on the circuit. The D2xB1LD2-H contains a supervisory diode and duplicated pluggable terminals that not only simplify installation but also enable a 4 wire connection. The unit is UL, cUL & ULC approved for Class I Div 2, Class II Div 2, Class I Zone 2/22 as well as IECEx and ATEX certified for Zone 2 and 22 hazardous area applications.
