Nice find, Steve! This looks very interesting. I really like the idea of cutting your stock wattage roughly in half but almost doubling your lumen output . The specs on this ad appear quite reasonable with 25 watts generating 1800 lumens (only 72 lumens/watt). Based on this info, these bulbs could possibly be a good upgrade for our hi-beam halogen bulbs. I already have LED hi-beam bulbs (10 watt bulbs with 800 lumens) so I may give this a shot myself to improve down-the-road projection. It would be good to know the color temp of these bulbs, hopefully not > 6K, to get a good color-match to HID lo-beams. Whoever installs these first, please be sure to give a review.
