Top_speed, I don't disagree with anything you said. I guess my point, which I didn't make clearly, is that I'm not optimistic that there will ever be a drop-in LED replacement for a filament bulb that works half as well as a lighting system designed specifically for LEDs.

That doesn't mean I wouldn't love to be proven wrong though. One thing I wish my K16 had is LED high beams. I'll continue watching your tests with interest.

This will come in time for all new bikes but most likely will not be retrofit able.

Of the lighting options out there, I've used the old incandescent, halogen, HID and LED. Numerous varieties and wattage of each. Different versions of the last three in my car. My preference is for the light offered by the LEDs, both CREE and now Phillips LMZ 45 watt bulbs.

This is because of the even light dispersion with even color across the field of view. While the 35 and 50 watt HID bulbs I have used did pump out the lumens, there is a hot spot and color shift, let alone the long warm-up time.

I suspect that the nature of the LED light is what makes the illumination seem different. Until we here in the US are able to have laser automotive lighting, LED is tops for my night travel.

The difficulty with nearly all LED H7 replacement bulbs is the fitting into the small space under the waterproof cover.


The high power LEDs have a ballast similar to HID lights.

In the mean time, we have the Clearwater Sevina LED light to blast a path thru the night.

Maybe I'll be making a trek over to see a game or two myself. I loved the area last year at the MOA Nationals. The people were the most friendly I ever encountered.

SKOL!

It seems to me that I'd replace the speakers and fit high powered Erika's or Olivia's there, no? :-)
I wanna keep the covers intact and on mainly keep the dust, dirt and moisture out of the entire headlight housing. Drilling a big hole for the fan and then using "plumbers" putty around it was not my idea of a slick install.

ABBA fans everywhere know exactly what you mean. ;
Ahhh.... "Diggit the dancing queen".
The Sound & Stage Lighting Co. that I own has done many of large or famous bands and acts. Abba just happened to be one of them, albeit it was just a one night gig at the Geneva (NY) Theater one hot summer night. One of the members was from Ithaca NY, and so Hobart College booked them along with us doing the Sound & Lighting (mostly Par64's back then, in 1K watt ea.) If I remember correctly, it was an 120 Par (can) contract. Not huge, but plenty good enough. Back-then, our milestones were Show-Co, then on tour w VanHalen boasting 800 1K Pars! Rush was right up there also, but again, we didn't have those guys under contract

"Spin Doctors" was one of later bands we toured with. My brother and I who owned the Co. (never could keep a relationship g/f or wife b/c of this) eventually hibernated it. I still have truck loads of equipment, including the high powered lasers. We don't wanna sell it, guess it's memories. I have pulled some of it for some smaller gigs now & then.

I did mention...Better halves hate this business? lol

Space is tight considering the fan. BUT!, I have found a few that fit. The 3600lm one I have in now is crazy mad bright [in the garage!], and doing the A/B (towel dowser) between the halogen and the 40w LED, it's not even close.

The real test is teh light coverage out in the streets. Yes that FJR video says it all, but my lamp is also twice the output of his, PLUS!... there is an issue with the "pod" that goes around dual beam LED's (or HID's). This tries to fool the light beam to the down part of the reflector. In doing so, a lot of efficiency is lost. I have tried 3 pairs of these Hi/Lo's in my snowmobiles, with slacking results so far.

Nothing however has been so bright as these H7's I've currently go in. So, I'm hoping they pass my road test.

I agree that matching the halogen filament position with the LED emitter is critical for matching the lighting placement.

What concerns me most is how my eyes are able to use the nigh time illumination. Cameras and camcorders "see" differently than my eyes. We saw this well demonstrated when conducting the Big Dallas LED Comparison test. the photos just didn't convey what our eyes saw.

Anyway, I have two different LED orientations in my car, and will be driving 500 miles at night. This will allow me to compare the effect of the orientation, and illumination.

What I have noticed so many times riding is that one must be careful to not have a hot illumination spot because your eyes adjust to the bright spot, denying adequate vision outside that hot spot. Worse yet, when riding around a corner the hot spot is off somewhere you aren't riding, making a period of night blindness.

What I prefer is an even illumination, with a distant illumination of the retinas of road critters and especially deer.

After seeing RL's image, it reminded me of another project I have in the works...

Upgrading the Halo (angel Eyes) LED chip. I'm playing with the idea of 10w LED, which should be about 5X the intensity of the current ones. This should make the Halo's DRL useful. Probably 5watt is more in reason however.

Here's my images of that project.....




Now if you look at the top, that is the LED diode. The first trick here is to have the board accept the higher powered LED, also still have headroom for the thermo disbersement in the heat sinks. I've tested this by using a laser heat gun (like what HVAC guys use). After 30mins of parking light-on, I can only see a 6F degree rise. I have to figure out the tolerance and headroom, but it seems like there is some. Well, enough for 5watt I'm sure, but a 10 may be pushing it.

Do the Euro spec bikes have brighter Halos?
If so, would it be as simple as switching out the module?

I believe those are completely different in that they're not a single LED dispersing light into the angel eye ring.
