Total Internal Reflection (TIR) Optics 

To harness the power of the CREE XM-L2 chips the Spartan MKII Series lights utilize custom TIR optics. TIR optics allow us to control the power of the CREE XM-L2 chips to project the light in a desired beam pattern as well as eliminate wasted light refraction. Our custom clear polycarbonate TIR optics achieve a 93% transmittance rate meaning they are able to utilize almost all of the light created by the CREE XM-L2 chip without any light transmittance loss issues.

Each Spartan will be custom tailored to your needs based on your TIR optic selection. Our TIR optics are also designed to be interchangeable in case your needs ever change later down the road and you decide you would like a different optic or color choice.

TIR Spot Lens

The Spot Lens is designed for those requiring a tight beam focus and extreme long range vision. It is ideal for faster driving conditions and where side vision is not as critical. This lens produces a 10° circular beam pattern for maximum down range vision. 

TIR Driving Lens (SAE style)

The driving Lens is designed to give you a low but wider field of view light output while maintaining a sharp cut off line. This lens produces a 17° by 11° rectangular beam pattern which is ideal for most general driving conditions. SAE standards require the sharper cutoff line to prevent hindering vision of others. To maintain this safety standard the lights need to be mounted low to the ground, such as a fog light application.

TIR Ultra Short Throw (UST) Lens

For ultimate near field vision, the UST is an optimal choice for reverse lighting, low mounted front fog lighting and side facing ditch lights. This lens delivers a wide angle 65° by 65° degree output pattern. 

Lens & Beam Output Options 

Choose a clear lens If you are looking for a clean pure diamond white output with maximum brightness.

When selecting a clear lens the pure white light from the CREE XM-L2 chip will pass through as originally created and will output in that same diamond white color. The purity of the CREE XM-L2s diamond white light paired with our polycarbonate high transmittance lensing is unmatched. Definitely the choice for those wanting to keep a pure white beam output and wanting to have their lensing look slightly less aggressive. Even with a clear lens, you will still maintain the custom amber backlighting option. 

Alternatively, you can select Amber lenses for a more distinct look and to transform your lighting output to Hyper Optic Yellow output.

When selecting an amber lens, the diamond white light from the CREE XM-L2  will be filtered through an extreme amber resulting in a high performance Hyper Optic Yellow light output. Hyper Optic Yellow Output is designed to enhance visibility in challenging driving conditions like fog, snow, rain, and dust. Hyper Optic Yellow also reduces glare and boosts contrast, ensuring you can see more clearly in any adverse condition. Hyper Optic Yellow delivers a more unique color output, as well as a more aggressive amber look to the lens when the lights are off, both of which can further add to their aesthetic impact and help your truck stand out from the rest! 

Customized Extreme Amber Backlighting 

Each Spartan MKII Series LED Pod Light features fine tuned extreme amber LED backlighting to give your truck a subtle yet refined aggressive aurora. 

This backlighting color has been custom tuned by the F150LEDs team to match Ford's raptor amber styling color as well as to match our other extreme amber lighting products such as our raptor grill lights and side vent lighting kits etc. 

Your Spartan Series II harness has a built-in switch for the back lighting but you can also connect it to your truck's DRL/side marker lighting or, if equipped, your vehicle's AUX panel switches. The use of this backlighting is optional and not required but we have a feeling that you are definitely going to want it!

We pride ourselves on the details and guarantee our custom backlighting color tone & brightness is superior to any other options available anywhere. 

Harness Application Details (included)

Your Spartan MKII LED Pod lights include a customized tri core connector to mate with any MKII harness you select.

Your Spartan MKII lights are also compatible with Spartan harness upgrades like the Headlight adapter series for backlighting, premium in dash switch upgrades, AUX wire connectors & wireless remote/strobe functionality kits.
