3d 4d 5d 6d 7d LED Light Bars

So, What’s the difference between standard classic projection LED bars (2D), 3D LED bars, 4D LED bars, 5D LED bars, 6D LED Light Bars, 7D Light Bars, 8D LED Bars


If you are an avid off road enthusiast and have been considering purchasing a shiny new set of off road LED lights or an LED light bar or two, you have probably heard of the latest technological innovations and upgrades in the different types of cutting edge optics, mirrors, and lenses that are now being used in the newer off-road LED lighting systems; a.k.a. 3d LED lights, 4D LED lights, 5D LED lights, 6D LED lights, 7D led light bars, and now the supposed 8D LED lights.

As most of us already know, off-road LED Lights are comprised of basically LED chip sets assembled in a specific configuration, that utilizes optics, reflectors, and lenses to either enhance or alter the beam of light coming from the off-road LED lighting unit. Depending how much power the actual LED’s themselves are rated for in terms of wattage and lumens, in culmination with the design of the lights themselves, including the degree of angle of the light beam being projected, and then finally compounded by the optics and lenses; determines what type and strength of light beam pattern you will ultimately end up with. Different lights for different applications in essence. You know, the right tool for the job and all… 😉

2-D LED Off-road Lights and 3d LED Light Bars-

The classic LED light bar is the most common type of 4×4 LED light bar to this date. These classic off-road LED bars utilize a high powered LED chip, high tech internal circuitry and technical components, and mirror finish reflectors to pierce the dark night in front of your vehicle so you can see safely while tearing around the trails at night.

4D LED Light Bars-

The growing in popularity 4d LED light bars are quite a bit of a different breed in terms of internal components. 4d LED bars utilize the same technical components as a classic off-road LED light bar, but with some additional components used to magnify the actual beam of light. The 4d LED light bars implement a special type of “domed” or “fisheye” projection lens over the actual LED itself, which when in use, intensifies the projected beam of light in a an extreme wide panoramic angle (supposedly more so than the classic LED light bars). One apparent downside to the up and coming 4d LED light bars is that they do not work the greatest if the light bar is purchased in a stand alone flood light beam configuration.

5D LED Light Bars-

5d LED light bars are another type of off-road LED light bars that are growing in popularity among the off-roading crowds. The off-road 5d LED light bar’s performance can be simply summed up as comparable to a 4d LED light bar. Some of the differences that the 5d led bars implement are basically additional reflectors and optics that work hand in hand with the actual LED. One of the biggest differences is the implementing of a special “fisheye” lens coupled with special optics which achieves a much smoother yet more defined plume of intense LED light down range when compared to the likes of a 4d off-road LED light bar.

6D LED Light Bars-

Most 6D LED light bars utilize an innovative design that incorporates a series of different lenses, optics, reflectors, a hexagon lens contour, an anti-glare hoods to prevent light from improperly escaping the unit, automatic on and off sensors, etc. Basically the off-road 6d LED bars incorporate a mix of several fish eyed Spot LED units that can project a beam of extremely focused light along with the Flood LED units pushing a much wider and taller beam pattern(D-shaped projector lens) that creates a large bright cloud of extremely intense, blindingly bright light.

7D and 8D LED Light Bars-

The latest addition to the off-road LED lighting market are the 7D LED light bars. 7D light bars supposedly utilize the latest and greatest in terms of cutting edge LED technology and high quality materials such as reflectors, optics, and lenses to achieve what some call the best off-road LED light beam to date. 7D LED light bars utilize the same components as all of the other led light bars, just assembled differently, and with some additional components. Some of those additional components are- a wide beam “fish-eye” projector lens, a narrow beam fish-eye optic projection lens, special reflectors and bezels to accommodate both spot and flood beams, additional layer of optics, etc. Some of these newer led off-road light bars are coming with other features and benefits such as- daytime running lights (DRL), Multi functional, Auto On and Off, Hexagonal Anti Glare reflector technology, adjustable/dimmable, wireless/remote control, Bluetooth/Smart device enabled, inter-changeable lenses, multi color (RGB), HALO, adaptive, etc.
