What is the difference between the Dually and the D2?
The Dually and D2 are housed in the same cast aluminum housing and have the same shape and profile. The difference is what's inside. The Dually uses our Hybrid Optics System in a 4-LED configuration which comes in either Spot or Flood options. It produces 1,568 lumens at only 15.8 watts and 1.1 amps. To put that in perspective, it uses less power than it takes to use your turn signal. This light, in it's Spot configuration, can out-distance the D2. The D2 has 6 LED's that utilize our Specter Optics System, which comes in either Driving or Wide configurations. It produces 3,096 lumens and uses only 34.5 watts and 2.5 amps. The D2, with it's driving beam, produces the perfect combination of distance and width for lighting up the road or water in front of you.
What is the difference between the Hybrid Spot and Flood beam patterns?
The flood configuration can be visually identified by it's higher trough, compared to the spot. Our flood optic illumates at a wider beam angle, but does not go as far. The spot configuration can be visually identified by it's lower trough, compared to the flood. Our spot optic illumates at a greater distance, but does not reach as wide of an area. Both of these lights are great for their individual purposes, and if desired, they can work together for a perfect combination of distance and spread.
