#4500k hid vs halogen plus#

Along with the LED lamps, that premium pays for unique front-end styling that apes the CTS's, a four-screen rear-seat entertainment system that can play something different on each screen, heated and cooled cupholders, a special overhead console, spectacular two-tone inlaid wood and handsewn leather trim on the dash and door panels, plus glove-soft aniline leather seating surfaces. The Platinum model costs $10,705 more than an Escalade optioned as close as possible to the Platinum's equipment level. All anyone is saying is that it's 'considerably more' than HID at the moment, though with time and volume production LEDs should achieve parity or become cheaper. By comparison, the halogen beams appear dangerously inadequate - a pool of yellow light right in front of the truck with far less reflection coming back from road signs, less side illumination, weaker high-beams, etc.Ĭost is the big unknown. LEDs light up the same pattern on the road, but the edge of the light is less sharply defined. The upper cut-off of the low-beam light pattern seems sharper on the HIDs, because there is a sort of 'eyelid' cutting it off until you turn on the high beams.

That means the LEDs must focus their light right where it's needed, so there's less sideways scatter and the high-beam pattern appears maybe twice the vehicle's height and four-lanes wide at a quarter-mile distance. This is in part because each lamp produces more lumens of light - about 2500 to the LED's 2000 total, though the total light perceived on the road is roughly equivalent. The HID lamps illuminate the sides of the road more brightly and their high-beam pattern is like a huge cone of light reaching quite high. The light reflected back from roadside signs seems much brighter with LED than HID.
