I came across some H7 bulb info. Phillips +130 is a high output H7 bulb which should put out somewhere around 2100 lumens. The Osram Ralley 65watt bulb 12 volt is essentially a H9 on a H7 base and produces 2100 lumens. Flosser makes essentially the same H7 bulb rated as a 80watt at 13.5 volts and makes the same 2100 lumens.

Those are the brightest H7 halogen bulbs

For anybody who plans to run this... make sure you install a wiring relay harness. If you try and use that kind of bulb with your factory wiring there is a VERY GOOD chance you will MELT or start a fire. This was a very common problem back when the good ole Xenon Bulbs hit the market. They were double the wattage of a standard bulb and looked good, but caused a lot of issues with wiring harnesses.

You'll want a wiring harness with relay so that you power these kind of bulbs from the battery instead of your regular harness (the regular harness from your truck will trip the relay, pulling power from the direct feed off the battery).

HIGHLY recommend anybody putting these in, that you put a new relay/harness in. Pretty straight forward stuff. Most harnesses come with the connector you need. Connect to battery/ground, connect one end to the bulb, the other end to your factory harness, you are done. Simple and ensures you don't fry anything or cause a fire. (ask me how i know this lol)

Everything I've read is that the draw with any of those bulbs is less than 10 amps. The 80 watt bulb is the same wattage as the 65 watt bulb but rated at a different voltage. But if you try a 100 watt bulb, then melting wires will probably be an issue.

The Flösser and Osram bulbs are electrically, optically, functionally, and qualitatively identical, but they are labelled differently. They are both built in Germany to exactly the same specification: an H9 burner on an H7 base, 65w at 12.0v, 2100 lumens at 13.2v. Flösser's box says "80w" while Osram's says "65w". This is not an actual power difference, it is a test voltage difference. Flösser power-rates their bulb at 13.5v rather than 12.0v. For any/all filament bulbs, the wattage rises exponentially to the power 1.6 with voltage increase. So a bulb rated 65w at 12.0v will be rated 78.5w (printed as 80w) at 13.5v. It's not two different bulbs, just two different test protocols. On the test bench, the Osram "65w" bulbs and the Flösser "80w" bulbs all test out at between 63.8 and 65.4 watts at a constant 13.2 volts.

You realize 10 amps is a LOT of power right...

As I understand it, the light fuse is rated for 10 amps. Most high beams are rated at 65 watt. Lots of people are using these on VW's and other cars without issues.

Someone calculated the amps...

"I don't think I'd sweat burning anything out. 55w bulbs draw 4.6 amps at 12 volts and 65w bulbs draw 5.4 amps, no biggie and you don't even have to change your fuses."
