The Supernova V.3 LED headlight bulbs are an upgrade over the V.2. This new version 3 still features the flexible heat sink designed for fitting in tight spaces but has the new Philips Lumileds ZES chipset that better mimics the original halogen filament bulb. This means better light output and a better beam pattern. The V.3 will produce 2 times the amount of light intensity than the V.2 did.
