Cyclops 3800 H4 LED Headlamp Bulb

[JTGS850GL]

One issue I would be concerned with using that setup: With the rear of the fan open it would seem to be vulnerable to getting jammed by a loose wire or some other debris. Wouldn't there be enough room to cover the rear of the fan assembly with a wire mesh or thin metal plate? Using 20 gauge sheet metal it should only add 1 mm or so to the overall length. Virtually no increase in length if you recess it slightly. If so, it would eliminate this potential problem. I know that I have a lot of loose wires in my headlight bucket.

On my bike it is so close nothing can really get in there, and I don't have any loose wires in that vicinity. However, you are correct a thin piece a metal can be cut out with tin snips and some holes drilled in it to allow the air to come through. The mounting screws are all ready there.

That's all well and good academically but how does it perform in the real world? What's your take riding with the new bulb at night?

I'm sure my very analytic answer will be "it's like daylight" just like all the other LED bulbs.

here is a comparison from a thumper.

Before doing the write-up, my basic assumption is that the Cyclops 3800 is the highest power LED (based on current consumption and specs), so the main issue was what does the beam look like mounted in the 8" trainlight? I tried to address that by looking at the near field patterns and how well cutoff performed comparing Halogen and 55W HID of which it did better in both cases.

The link above will tell you that the Cyclops is just a little less intense than the 55W HID in some directions but probably a better spread. That is about All I'm going to have before pulling my fairing apart to mount the thing.

I should mention this was late at night and I forgot to put the camera on manual. So the distant changes in light between high and low beam are at least 50% more from what you see in the video. The close in flood lamp is probably about right.
It is also interesting to look at the side of the motorhome, as it shows pretty clearly the effect of the cutoff and the change in dip angle as the Cyclops is switched between Low and Hi.

The video is taken with the camera in the dark taken from behind the bike with a distance of about 7ft from camera to headlamp. I start in Lo beam and then switch a couple time between Lo and Hi. returning to Lo beam, I then switch the 18W Work light on and Off where you will notice the increase in lighting directly in front of the bike. Finally all three are turned on.

None of the beams was actually adjusted except that the Cyclops had been previously focused using the PVC spacer.I popped the bulb out of my spare lense and into the lens on the bike.

This video is of the Cyclops 3800 with both Low and High beam (40 watts rated/32Watts measured) as well as a work light I got off of Amazon ( 18W rated/12W measured). The flood light is used as a close in driving/fog light with a 30 degree flood pattern for close in. I have it controlled by a left hand switch push button. I have played with a cutoff for it but the video is the unshielded lamp which adds substantially I think.

If you don't know how far the beam should shine, here is a link with some reference information for Dual HID lights on a CAR. The CAR had dual lights where as the motorcycle has only a single (excluding the work light). As we can see 100 ft is generally a minimum strong light region and the HID should extend well beyond as is also in evidence in this video.

Great work, Jim! I was pretty sold on the AVDmonster light due to BWringer & ADVrider.com reviews, so this is great news! I would really like to see the AVDmonster side by side with this, but it seems as if the power consumption says it all.

I wish someone who could compare different reflector assemblies and optimize the focus as you have. it seems as if the 7" is definitely much better than the 6", at the standard model comes with a 7", & the L model likely holds to its theme of its targeted looks over function.

My 7" GS650 6H5 Koito reflector was a huge upgrade with halogen bulb over the stock sealed beam. broke that, deer, accidentally downgraded to a good looking GS1000L chrome H4 assembly with a $25 Chinese fleabay Cree "30W" h4 LED replacement. Pattern width was close to the 7" h5 koito 60w, but not as good, not focused, and not nearly as intense... have to swap a halogen back for comparison sake.

Thanks, sorry I was only looking for the best .

I suspect that you will see a similar focus sensitivity for the smaller reflectors. As mentioned the Cyclops tech support claimed that generally they work well with most conventional reflectors and I saw nothing to suggest otherwise in my testing using the 8". In fact it would seem the 8" is not much different to the smaller bulbs they typically fit.

Thanks for all your input everyone. It's been a while since I was on this site, and it has only got better.. I wanted a decent LED H4 replacement for my GS1000 S and reading through these threads has saved me a whole lot of time and effort and probably mistakes. I have just ordered the Cyclops 3800 with the 7000 lumen upgrade. Wish me luck! Now for the indicators, tail light and instrument lights..... And yes, the after market stator and series regulator are already on their way! Big road trip planned and I want to make sure everything works!! Smithy, Auckland, New Zealand.
