H1 & H4 Halogen Bulb Performance
 

Good morning all...

We're revamping the original Audette Collection site to return it to it's original informational format. As part of the process we will be adding additional current information. The first, added yesterday, is a short look at current H1 and H4 halogen technology.

There’s a lot of attention on LEDs these days and they’re great. But meanwhile halogen bulb technology has been moving forward rapidly. Bolstered by content by Audette Collection friend and informal consultant Daniel Stern, the article goes as deep as most of us want to go. Also, out of the hundreds of options available, many with promise of greater illumination and most with fancier packaging and catchier names, we have chosen only one halogen bulb to sell based on expert advice from Daniel. The article tells you which one and why we chose it. You will find it at:

The latest technology makes halogen bulbs an inexpensive and effective upgrade.

Cheers,
John

Great read. Thanks for continuing to progress automotive lighting science among the Pelican community.

What bulbs will you be sending with the H4's that you're currently restoring for me?

Also, perhaps a typo in the last sentence here?...

"“Require” is squishy here — if the wiring on the car is in good shape, then there won’t be any problem provoked by these bulbs. However, any bulb will give more and better light with low-resistance feeds and grounds. The will bulb’s lifespan will be shortened."

How do these compare to Philips RacingVision H4 Headlight Bulbs?
