My experience with LED H4 bulbs confirms it. Light output is more than plentiful at over 2000 lumens per bulb, but there is too much foreground light. This becomes an interesting case of blinding yourself.

Dazzle to oncoming drivers is not as much an issue as an HID conversion.

I'm guessing they were HID bulbs in a lamp designed for halogen bulbs. I have had direct experience with one of those install. It was completely unusable, sure you got a lot of light but it had no cut off, very glaring, impossible to use in rain or fog. > > The good LED lamps are designed as a unit, bulb and reflector.
