Think your miss understanding/reading Alex.
Wattage is the current draw on the electrical system no matter the item.

Lumens is how you do your calculations. Because that is the brightness level. And can not be changed between output devices.

A 60w halogen will have the same amperage draw as a 60w led/SMD light.
However the lumens will be different. (Generally higher with the led/SMD)

This is why as you mentioned and we all see at the supermarket 6w led units = to 40w halogen.
10w = 60w, 18w = 100w etc.

You then have differences with the led units (a discussion we have had in the other group chats)
One 60w led headlight unit might have a higher LUX rating than another 60w led light unit.

Like anything the more you look the more complex it can become
800lm = 60w incandescent, 8-12w led.
1600lm = 100w incandescent, 16-20w led
What I understand from this is, the led headlights are brighter, throw further but they alsoare the same wattage as a normal globe, not less like house lights are.
Led does not throw further. For the equivalent output.

-with out assistance from a projector lense or a reflector designed specifically for the led.
I.E: J.w speaker, truck lite etc.

The new retrofit kits like Alex has used and tri. Are significantly better than previous generations.

The significance is still in the lens.
3 years later

3 years later i finally get around to doing this...

ended up picking up a holden 80amp alternator from the wreckers. conversion looked pretty simple but on the 164 alternator the screws holding the rotor to the front housing are in from the back making it impossible to detach it from the front housing. as opposed to the later style that has 4 screws holding the housing to the rotor and screwed in from the front.

@Angus242164 did you encounter this problem when you did your conversion?

I just fitted a P80 alternator, a few mods to the housing and a new adjuster and it works a treat.

I didn't encounter that issue with what I did, everything was a direct fit (between a 240 alternator and a VN alternator), I would say that the 164 alternator must be from an earlier generation of Bosch alternators.

I have a modded alternator which I think came from a 140. Looks like a Commodore main body.

Located in Melbourne.

    what amperage is it?

    It is in a box somewhere. From the ad:

    "The part number of the main body is a commodore so almost certainly an 85 Amp alternator. Pick up only, too heavy to post."

    The sticker on it looks like 85 Amp too.

    $50.

    where abouts are you located ?

    wondering how to wire up the holden alternator as its slightly different to the old 55a one

    would really appreciate any insight

    pic one is the new alternator with two wires coming out of the regualtor one with a spade connector on it. i assumed this was to connect to the excite wire which is connected at D+ on the old regualtor. battery wire obviously goes to B+.

    but the volt meter shows the battery isnt charging

    My memory is hazy as it's been many years, but the two pins of the regulator plug should be marked with a letter each.

    I think they are:

    L - light - connect to the warning light wire to the cluster.

    S - sense - connect to the positive battery terminal.

    This is run to the battery directly on the OE vehicles with this regulator, (rather than to a nearby power feed), as it's used by the regulator to determine the actual voltage at the battery, to control charging more accurately than earlier alternators.

    Yes you're spot on. Managed to work that out from a commodore forum

    You did well to figure out any useful information from a Commodore forum! They don't have a great signal to noise ratio.

    Haha it was more trial and error. Weird thing I've noticed is connecting the sense wire creates a high pitched frequency. Not sure what that means

    13 days later

    S wire should be an ignition source if its connected to battery it will drain your battery if it sits for any length of time. If its a noise through the spreakers its earthing issue that why that little black box is on the back of the Alt is for radio noise supressor. But if it's a hum out if the alternator when S wire is hooked up more than likely blown diodes on the rectifer plate inside the alt, its pretty common on bosch holden alternators, Altho there cheap and readily available every where,
