Saaz, what are your thought on these?
http://www.aliexpress.com/item/New-Brights-LED-Headlight-Bulb-H4-72W-6600LM-COB-LED-Lamp-Replaces-Halogen-HID-Bulb-Hi/32291933258.html

I notice on the ones that you originally put up ( http://www.aliexpress.com/item/Super-bright-3200lm-h4-led-headlight-hi-lo-beam-car-led-h4-Headlamp-Bulb-35w-12V/32221003713.html ) the two LED light sources are offset similar to what the 2 wires in the standard lights are. Does this make a difference?

Cheers.

I would not use the ones in the first link. I have some of them, and the beam pattern is rubbish, the beam pattern is all over the place.  Also very hard to fit as the clip has to try and fit over the fan. The ones where the LEDs mimic the position of the H4 filiments are better.

Does anyone else in Perth want a set of these ordered? I will hold off until tomorrow in ordering (I have a blown left globe so need to do soon).

The offset is preferable because the parabola reflector of the light fitting is designed to produce a projected beam by the light source being in the focus point.

The ones saaz is using has the Low beam LED is on top and further forward in a slightly out of focus point of the parabola reflector, and the High beam LED on the bottom and further back and in the focal point of the parabola.

Therefore the Low beam reflects off the top of the reflector. This directs the light downwards and gives a very well delineated low beam and spreads the beam over a wider area. (You might have noticed Halogen H4s have a shield over one filament.  This is the low beam one)

Unlike normal H4 Halogens,  the LEDs saaz uses, when High beam is turned on, both LEDs are on at the same time. So he gets the benefit of a focused high beam and the spread low beam.

I came close to ordering a set last night, but stopped because I didn't have my credit card handy.

My only concern is the fans.  I'm concerned the bearings will wear out like PC fans do. But saaz has done some phenomenal distance using these LEDs so the boosts confidence.

I note the latest ones on eBay only use a heatsink, no fans.

e.g.

Some also have the driver integrated in the mount.

No problem. Will hold until end of day to see if anyone else wants. Spoke to Saaz last night and for a few reasons he dais these are the better ones to go for. Works out about $100 a pair so a bit more expensive than halogen but much better light from what I saw on Saaz's bike.

I hope your reflectors are up to the task. mine were not , so i went the HID route.  relectors can be redone, resilvering kits will not handle the temp of the bulbs.  these guys can do plastic ones for a $100 minimum, on the Sunshine Coast Qld

I find the LEDs run cooler to the touch than H4s (hottest), Hids (next hottest) then led (can't even feel the headlight is warm)

Be interesting to see if they both turn up at the same time.

I'm keen to see how these fit and perform in a ST1300, and if found to be satisfactory, I'll be ordering a pair.    :popcorn

If they do 50,000 hours as other LEDs claim, I'll be keen because I hate changing bulbs in the ST.   :'(

I don't know about the 50,000 hours bit, but they have lasted 22,000kms so far. OEM trophy bulbs (Osama Bilux) lasted 50,000kms before one low beam went.

"Osama"??  or Osram?

I think you read too many Middle Eastern novels.    :grin

50,000 kays from a headlight is impressive.  I think it's always the low beam that goes because obviously it's the one that's on most of the time.
