One of the issues with converting H4 halogen to LED is the resultantly poor light pattern, at times just plain dangerous for other drivers. If you've got a vintage BMW or a retro-customisation (like mine) which is using 7" round H4 housings or sealed beam, then there is a great replacement I was made aware of today.
Holley is producing a LED based 7 in. round - modern-tech upgrade for old-school sealed beam headlight systems The unit is designed from the ground up to produce a bright accurate beam pattern, with quality components it appears. It should be a drop in replacement for the H4 housing. The light is available in two color temperatures - 3000K and 5700K, and the brightness is 32,000cd (Low) / 53,000cd (High). Current draw is 25W (low) / 30W (high) which is half the power drawn by a standard H4. Price is "competitive" with roll your own solutions, $200 Yankee Bucks.
