1. Why makes your LED light bars better?
There are quite a few suppliers of raw LED chips and many more models to choose from. To start with, we test a majority of LEDs offered by every major company out there in our labs to verify their specifications with our actual testing equipment. We only select those that make the cut for performance, consistency and pricing and then go to round two.
The higher power LEDs used on offroad lamps are usually offered at 1 amp, or roughly 3 watt, 1.5 amp, or 5 watt, and 3 amp, or 10 watts. Just about every company out there run these high power LEDs at their max drive current which results in lower efficiency due to thermal considerations. When a 5 watt LED is driven at full 5 watts, the efficiency is roughly 100 lumens/watt at the chip level, but when the same 5 watt LED is driven at 3 watts, the efficiency increases to 120 lumens/watt. We utilize high power 5 watt LEDs and drive them at a reduced current to not only improve efficiency, but also reduce heat output, offer longer life, and save weight off the housing.
Of course, it doesn't stop there. Our quality control checks allow for very little deviation in LED color temperatures and high CRI levels to offer the best combination of performance and light quality. Lastly, our proprietary power driver designs allow for redundancy and long life, which many others simply cannot offer. Everybody quotes 50000 hour life, but did you know, most LEDs actually fail from power driver circuitry? Any time such lofty lifetimes are quoted, make sure to take it with a grain of salt!
2. XYZ offers more lumens, why don't your products make the same, if not more?
For starters, not all lumens are the same. Many companies out there simply calculate the raw lumens offered from a given LED at the max rated current and multiply them by how many LEDs they have in a package, which can grossly inflate lumen figures. Some don't take power driver efficiency losses into account. Others don't take optical design and losses from the cover lens into account. So before you judge, don't use lumen count as the most important performance metric, because most certainly, you will not be comparing apples to apples.
Another thing to consider is, not everybody really needs the ultra high lumen levels of some light bars out there. Unless you are a professional that needs the utmost amount of lighting in the middle of the night while competing in the Dakar, chances are, you just don't need the stratospheric lumen figures that come with wallet busting price tags. We have plenty of feedback from customers who have installed our products for both recreational and racing use, and we guarantee you won't get a better deal at our price levels.
3. What type of beam patterns do you offer on your LED lamps?
Our lamps come with a diffracted reflector design that offers a mix between pencil beam and flood beam. The advantage to this design is the reflector doesn't become so narrow that much of the light ends of reflecting multiple times within the reflector, resulting in efficiency losses. You get a beam that is ideal in most applications, with a majority of the light pointed straight ahead and the diffraction scattering some of the light to a wider flood beam. More light exits the fixture with this efficient reflector design. Keep in mind, even the best aluminum used in reflectors are only 95% efficient, and each time a light ray reflects off the surface, 5% of the light output is lost. In a deeper pencil beam reflector used by others, the rays with shallow incident angles from the LED bounce off the reflectors multiple times before it exits the fixture. Also, even the best optical lens covers only transmit 93% of the light, so we use the purest polycarbonate resins to ensure the highest transmissivity.
4. What input voltages does your LED lamps accept?
Our LED light bars are designed to work with DC input voltages from 9v to 30v. This allows use with any 9v power source, 12v & 16v power systems used in most automobile and powersports applications, 24v used in more heavy duty machinery and 28v power systems used in aviation. The power driver regulates the current driving the LEDs so the input voltage does not affect the brightness of the lamps, allowing you to get the full brightness of the lamps regardless of the voltage supplied from your vehicle.
