Why not use for Low or High beams if they are 1800 Lumen?
Just being brighter than the stock bulb is not enough when it comes to vehicle lighting. The bulb has to have that direct point of the bulb matching to the focal point of the lamp to create the recommended beam output needed for safe driving. With the DX24LED Kit you have 24w of 360º panels of high power COB/Plasma (COB: Chips On Board) LED units which is much larger than the single point of a halogen bulb. The heat sink keeps these LED bulbs from over heating which would make the LED bulb fail. The bulb also has a LED driver to keep the LED pushing out the maximum brightness of the LED bulb, this also prevents static feedback and gives constant power to the LED bulb. They have instant on operation with no warmup but since the LED panels are much larger than the small focal point of the halogen bulbs the beam is much more spread out as seen in the pictures below.
