LED lowbeam experiment

[NeilBlanchard]

The VLED lights with the Cree element apparently use 27W each. They also have little fans on each, to keep them cool - maybe only needed in certain situations?

At $120 each, that is a steep price, but I think they are considerably brighter than typical bulbs (2000 lumens vs ~1400?).

I bought the Cree h7 based led's for my Jetta.
Unfortunately VW has a weird low beam adapter/mount, so I had to grab a couple of those aftermarket HID bulb adapters for it.

Soon as I get the front end back together I'll get them installed.

Also got the H4 dual beam cree led bulbs for my bike.

I hate to spend any money on the Undieing POS because Im set on replacing it with 2015 SVO Mustang.
It could really use the LED trick. I am concerned by the 80 watts though.
It is 80 watts so figure 13.5 volts {+/-.75}thats 6 amps give or take.
My current halogen configuration is 55 watt @ 12 but again thier powered at 13.5vdc. =4 amps therebouts. no true savings there and significant extra draw.
I want more for less to reduce amp draw not more light to blind other drivers.
Im not sure why LED would draw more than Halogen so much for the eco line.

Drivers and cooling fans.
I feel the same way. I like led, but power consumption is so high.
If there was some way to divert the heat to output.......

Where are you getting 80 watts from?
the ones I got from
H4 9003 5K CXA 2000LM | 1 PAIR (BACKORDERED MID MARCH) B/O - LED - Headlights - Bulb Type
are 27 watts at 1800 lm low-beam and 2000 lm high-beam

Cree h7 based led's for my Jetta.
it may have been 88?? I just searched with his link.
then details were there.

Where are you all coming up with 80 Watts???

A car has at least two headlight bulbs for low beam running. So the average halogen setup needs 110 Watts of power (55x2). If you have a car that burns both beams when you select the high beams then your running 220 Watts when you use the high's

The Cree for H7's use 27 watts, doubled for a pair of low beam headlights that's 54 watts. That's less than even the 70 watts of most true HID conversions. Burn 4 (2 lows & 2 hi's together) and your still not drawing as much wattage as your car would with a pair of halogens low beams.

Next time you worry about wasted wattage, take your stock 55w h7 out of the headlight housing and hold it in your hand. Quartz is a good insulator, so if it is hot enough to burn your hand on the outside, imagine the power wasted as heat inside the capsule!!
That wire in the halogen capsule is radiating energy across a wideband of the em spectrum, where as the LED is mostly converting the watts to a handful of wavelengths in the visible light spectrum.
