Expanded Compatible DC Battery Voltage

  • 5-20VDC for LP220L versions
  • 5-20VDC for SP640L versions

Broader Temperature Range

  • CZQRW to continue to operate at 40°F to 131°F (-40°C to 55°C) for outdoor environments 
  • CZQRE now available at -22°F to 104°F (-30°C to 40°C) across all lumen packages

Additionally, we made the decision to keep the “SD – Self Diagnostics” versions of the remotes to operate with the QM LED HO SD Combo: 

*222XLW - ELA QM B L0309 SD M12

*222XM1 - ELA QM B T L0309 SD M12
