Something's wrong here. The 9000lm bulbs I see are 80-90 watts, not 30 as shown here. Goffy's 5000 unit is 30 watts.

Its Chinese 9000lm ;) or just a development of LED's which have been coming on leaps and bounds and Goffy's unit is now getting on a bit, is it 4 or 5 years old now which is a long time in LED world.

Read back through this thread and it seems that anyone that has purchased these items is pleased with the performance.

This light is fantastic.
Outperforms a very good H4 60/55 Halogen at night. The previous LEDs I've tried have all been very bright but poorly focussed for night riding.
This one is brighter yet and perfectly focussed.

Yes, working with positive earth on my bike.
Also ok with negative earth.

All LED's run at 5V internally, the voltage regulation circuit sorts out both the +/- problem and converts 9 to 32V to 5V. So the up to refers to dipped and main difference, nothing to do with voltage supply as long as its in range of 9 to 32V..

Actually, they use a constant current source rather than a voltage regulator. But the results are the same - constant output over a wide input range.

Have to be seen from the rear too. I don't want the dreaded "Hinda Civic Enema"!

Ordered these for the stop/tail light.

For brake leds, I much prefer the array type setups, where leds are arranged over a flat circuit board to spread out the light output. A common issue for the " bulb" look-a-like setups is they do not give a wider light spread even in the lamps with reflectors. So you end up with bright pin points for braking. I got my Commando brake led array from Dynamoregulatorconversions in UK and been quite happy with it.

I got mine from bulbsthatlastforever before they sold out to BCS. Thecompanydidnotlastforever. The board is still going strong.

I canceled the 1157 type LED and will get the lightboard taillight from Goffs.

Well, in that case the light board is definitively your best option.

But if you REALLY want that, then you should consider adding to it with LED indicators what double as stop and tail lights. Kinda like this…

Oh crap. you just added another layer of engineering! Maybe at some point, but I already have a long list of reliability and safety modifications on the winter project menu.
 
You realise Dan. if you lived in the UK you could pump all your excess electrical power back into the national grid and get paid for it!
 
Everything is on the UPS truck for delivery today. I am anxious to see some results.

Yes it shows several options on the connector link but I'm not sure which is correct.

Use the standard H4 wiring. Color codes of wires are in the schematics pages here in tech articles.
