FORT-A Linear High Bay Family Variants
One housing, two temperature answers: the standard FORT-A DALI base version for cool warehouses, and the heat-rated FORT-A-HT variant for foundry bays — both sharing the same tempered glass optic. Start from all variant families if you need another housing, or read the foundry heat-rating guide before picking a rating.

Picking the right FORT-A version per zone
Take the standard FORT-A DALI base version: 80-200W at 170lm/W with tempered glass optic, the lowest cost where air stays at 25-40 degrees.
Where air at the fitting holds 60 degrees and more — melt shops, steel aisles, dryer sections. The HT driver holds rated life at 60 degrees with D4i data where standard drivers derate.
Yes — HT over furnaces and dryers, standard DALI over cool storage on the same optic family, so spares and lux files stay common.
