2. HB3 is generally a full beam bulb and HB4 is a low beam bulb. HB4 bulbs therefore will have a shielded tip and a lower power rating. 3. HB3 bulbs generally are 60W at 12V (65W at 13.2V) and HB4 bulbs are 51W at 12V (55W at 13.2V). From here it can be seen that HB4 bulbs will give less light than HB3 bulbs.
As a rule of thumb, any halogen bulb with a colour temperature over 4200K is most likely non-road legal.

The light emitted by the H7 LED bulbs will be more powerful the higher the lumens. The maximum genuine power currently on the market is 8000 Lumens (for two bulbs). It has 30% greater power than xenon! It is simply impossible and useless for many sellers to sell H7 LED kits with more than 10,000 Lumens per bulb.
