Would like to carry a spare. Anybody knows what this one is?
LED Headlights: What brand/model is this one?
- Thread starter MidLife
- Start date
This was a tough one. A google search got me there in a fraction of a second. That said, the technology changes so fast that unless the bulb dies in a few months, you might be better off with what is available then. These typically have a life measured in years.
I found the brand for you, but they don't show an H4 lamp....

Great. Thanks. I'll try to contact them. It was a dealer install btw. Was trying to look for the same bulb as the wiring for accessories on this bike is "kind of busy" to say the least and I'd rather not take a chance with a different product for fitting considerations.
Although I never had a bulb failing on the road, I've always carried a spare on trips. Just a habit. May make an exception for this one....although I've seen reports of failures on the road.
Good point.
When I purchased the bike, the headlights' aim was completely off and I asked the PO how he could have ever ridden at night like that?
He didn't. Never rode at night and had no idea how far off it was (!). He had switched to LEDs only to be better seen during the day, he said.
Hence, they are obnoxiously bright white and kind of tiring after a while, although the coverage is outstanding.
I started with aiming low, fearing oncoming traffic wouldn't like it and flash, but now the aim is where it should be and haven't had a flash yet.
But I might look at something warmer for a replacement/spare (I was fine with 50 Watts Halogens).
Thanks for the advice.

Looks like Cyron has a fanless version now......
Looks compact and convenient to carry as a spare.
Cyron 1500 Lumen H4 LED Headlight Bulb - RevZilla
The low-profile design of the Cyron 1500 Lumen H4 LED Bulb ditches the external cooling fans found on most LED retro-fit bulbs in favor of a svelte on…

You might read some of the other LED headlight threads. I attached a few below to give you something to read when you are bored. 1500 lumens is almost nothing when you consider that Amazon has many with lumen ratings upwards of 30,000. Yes, many of those are inflated. You can get a realistic idea of the light output by figuring that light emitting diodes put out about 100 to 125 lumens per watt. Multiply the current draw (amps) by 125 to get an idea of its light output with no advertising gobbledegook. Yes, they can squeeze more light out of an LED per watt, but the color temp is usually in the 6000ºK range (think very blue white)
Edit: Oops, I meant to say above: "to get an idea of its real light output, multiply the lamp's wattage x 125....."
In the threads below, @spiderman302 worked with Evitek (i believe) to develop the shield that cuts off the light so you are not blinding oncoming drivers. I've used Evitek lamps in all of our cars and all of my bikes. I think they charged me a flat $10 shipping and it took about a week to come from China. No idea what will happen w/ the tariffs. Evitek's numbers are realistic and their pricing is about as cheap as you will find anywhere. Buying from amazon does get you nearly instant gratification.
Headlight LED -- F2 vs F3 vs NB35 | Lighting / Visibility
Has anyone else ordered the red F3 linked in post #41 above and seen red when the blubs are on? Is this seen by the rider, or only from the front of the bike? If so, is this really a problem, or just a small red glare? Thanks!
LED Headlight Bulbs | Lighting / Visibility
I have a 2010 ST1300 and I'm reading a lot of different sources/information for LED Light bulb replacements for my headlight (with some contradictions). It's September 2022.....Does anyone know what the latest and greatest LED bulb 'that fits' is and where to buy it? I'm willing to pay for...
LED headlight Hi/Lo brightness | Lighting / Visibility
I've been riding more at night due to the earlier sunsets. My STeed had LEDs from the PO. I can only marginally see an increase in light emitted when I put the "brights" on. Is this the typical experience with the LED lights, or is something amiss with my lamps?

Actually, it's current draw x 12 x 125.
I'm a fan of replacing stock lights with LED but I'm not going to get wrapped up in lumens blah blah blah. Why not? Because when I turn on my ADVMonster lights and even more so when I turn on the clearwater Kristas, you can't even tell I have stock lights. They become marker lights.

Thanks. Much appreciated. Have to catch up on that.
My mistake - I've edited my post. I meant to say, "to get an idea of its real light output, multiply the lamp's wattage x 125....."
Just keep in mind most of those threads are a couple of years old, and things have changed somewhat...for the better (usually).

Doesn't look like we can go to 30,000 LM from there....?

Thanks.
I'd like to look into fan vs passive cooling.
I cannot quite picture how a bulb with no fan and cooling fins inside the enclosed headlight chamber can be cooled as effectively as fanned bulb.
No, it doesn't. I looked at Evitek's website and there were two points that I noted. First, they quoted total lumens for a PAIR of lamps for your headlights and they quote total amps (and watts) as well. You have to read the fine print looking for what they are really saying. Second, many of their H4 headlight bulbs crank out 8000 lumens for the pair. If Evitek is not bragging about 30k lumens, then either they are far behind the curve (not likely) or everyone else is using 'music power' instead of rms watts for their amplifier. Sorry for the metaphor, but you get my drift.
Probably why the light output of those lamps you found is only 1500 lumens. The more light output, the higher the current flow (amps) and thus the higher the heat output*. They are deliberately limiting the current and light output to produce only the heat that passive fins can conduct away.
LED's convert 30 to 40% of the energy consumed into light, the balance goes into heat. Compare that old incandescent lamps put out 8 to 10 lumens per watt, and LED's today can exceed 125 lumens per watt.
