Technical:
- Not all LED lamps are equal. An LED is a flat chip that Produces Light from one side and heat from the other. One of the measures of a well designed LED lamp is its ability to deal with the dispersion of the heat. A poorly cooled LED will lose illumination the longer it is on.
- A typical light bar has multiple LEDs, each one with its own reflector. The light producing side of the LED is facing forward and the heat producing side is in the back. Normally a well finned aluminum heat sink is used as the frame of the lamp. This design can work well and has the advantage of allowing a low cost. low power LED, and makes up for it by using multiple lamps. An added advantage is that those multiple lamps can have different optics thus the ability to have Flood, Driving and pencil beams all in one package. Hella calls these lamps "Combos". One thing they don't do well is deal with ice and snow because all the heat is going out the back.
- The Hella Driving lamps use a different design. Instead of multiple low powered LED units, they use one to four much more expensive High Power LEDs and do it in a round housing. The LEDs are mounted on a cross bar with the light side pointed backward and the heat side forward on the cross bar which acts as a heat sink and is in contact with the lens. Several high quality Free Form reflectors, one reflector for each LED, collects the light and sense it was a single point of light, can send it way down the road. The Pencil can allow a newspaper to be read at 1.3 Km (4265 Feet).
- As far as Ice and snow, they should melt it as well as a halogen and better than HID. We submitted some Hella LED plow lights, with a similar design, to PennDOT for testing. They confirmed that they worked well in Winter conditions,
