This AD lampholder is engineered for HQI 150W metal halide lamps using the R7s double-ended base. The holder body is porcelain and incorporates a steatite bar, both high-temperature ceramic materials essential for sustained operation under the intense heat output of HQI sources used in commercial and horticultural lighting.

It arrives pre-wired with a 2×25cm silicone cable rated at 1mm² cross-section. The silicone cable maintains its insulating properties at the elevated temperatures inside enclosed HQI luminaire housings, and the 25cm length reaches most ballast terminal blocks in standard HQI fixture bodies.
