Our newly redesigned (2023) PAR46 FUSION 46LR GEN2 is a drop-in dimensional replacement LED PAR46 (5.75" diameter) sealed beam lamp for incandescent and halogen 12/28-volt PAR46 sealed beam bulbs. Heavy duty aircraft grade construction features 9,750 max lumen output (450-watt equivalent) with an 8 degree beam divergence. Guaranteed EMI/RFI-free, SmarTemp thermal management, powder coated housing for chemical and corrosion resistance, unbreakable UV resistant poly-carbonate lens with our PolyArmour hard-coat lens protectant, heavy duty brass wire termination studs with 8-32 SAE stainless machine screws. Engineered with 27 high-power thermally regulated 5-watt CREE XP-E series LEDs for an incredible 120-watt design. An integrated constant-current driver circuit senses input voltage and regulates the same stunning bright light output whether 28VDC or as low as 10VDC. Low current draw, long design life and minimal heat emission promotes continuous use in both daytime and nighttime operation to dramatically improve safety due to ease of recognition. Less current demands less work from your alternator which translates to more horsepower at the crank, improved fuel economy, and longer intervals between battery and alternator replacement SPECIFICATIONS: 8 degree horizontal x 8 degree vertical linear spreader optic,10-30 volts DC, 8.60 amps max @ 14vdc | 4.30 amps max @ 28vdc. 5,000hr design life.
