BASIC Linear G3: cost-efficient linear light engines with efficacy up to 168 lm/W — 770 or 1,100 lm on 280 mm, 1,550 or 2,200 lm on 560 mm, and 3,100 or 4,400 lm on 1,120 mm — in 3000 K and 4000 K, with lifetimes beyond 50,000 hours. They make a powerful system with the cost-efficient OPTOTRONIC and ELEMENT drivers, for office and industrial luminaires.
