LED Headlights Goff vs Cyclops

I’m not sure which one you’re referring to there?

Could it be your wiring that does that?

The 4 Goff LEDs I currently have fitted all do not use all 4 emitters for main beam. I had to use sunglasses to peer in there to be sure!

The Goff LEDs of mine are these, which draw 30 watts:

NEW 'DAYLIGHTER 2s' H4 5K headlight bulb replacements


This is our new British Pre-Focus headlamp LED, these fit straight into your existing BPF headlight with no adapters, resistors or anything else required, now with new shorter heatsink & improved beam pattern from Sept. 2019

Previous BPF LEDs have had the power limited by a very simple heatsink, the Daylighter has a more sophisticated heatsink allowing much more powerful LEDs to be fitted.

The power consumption on high beam is 10W on 6V so you can leave them running all the time you're riding and at night they will give a better light than a standard headlight bulb.

They're great for dynamo systems, used with a LED stop/tail they only use as much power as a Quartz Halogen pilot bulb

Dual Polarity, as supplied the standard Daylighters will run on 6V/12V as well as positive or negative earth systems so there's no chance of buying the wrong one.

Now also available as a 12V only high power version. Brighter than the standard version with the same improved beam pattern. These are also dual polarity & draw 12W.


The LEDs are positioned like the filaments in a standard bulb as shown here, this gives a good beam pattern, with main beam not 'up in the trees' like some other LED headlight bulbs.

Gotcha.

Could it be due to the power consumption / output / heat? Perhaps at 12W it’s ok to run all emitters whilst on main beam but not so at 30W ?

Went out tonight for a ride on the T140 with the Cyclops.

Chuffing brilliant (excuse the pun) !

The Goff wins on ease of fitment and cost.

Day time use is a draw as they’re both SO much better than ‘bulbs’.

But the Cyclops Ultra DEFINITELY wins for night time visibility.
 
an interesting discussion, thanks for the photos. The headlamp on my (Hinckley Triumph) Scrambler is hopeless for night riding, it is like an aneamic glowworm, (reminiscent of the 6v headlight on my C15) a Goff type H4 led might be a good investment, it ought to be a straight swap.
 
To use the either of the bulbs discussed here, which are H4, you’d need the bulb, a H4 7” reflector, and a H4 connector that you’d need to wire in (simple job, 3 wires).

The challenge at the moment would seem to be that most of the usual suppliers are out of stock of Lucas H4 reflectors.

The cafe racer in the side-by-side in my original post has (I think) one of these, which seem readily available:


 
Goff's 5K Daylighter arrived today and fitted.
What a difference!
 
I often say "I don't drive at night". But on a dank day you ride the lanes or even B roads in the quiet parts you will notice the beam out ahead of you on the road! More light is always better and the added + is less draw. Few things amaze me more than
LED technology. Remember what a difference Halogen was?
 
I met up with two mates at the weekend, in daylight, one on a new Sportster, one on a new RE 650, both with stock halogen bulbs.

We parked in a line and compared the headlights (mine with the 5k Goff).

Goff sold two more 5k LEDs that day !
 
I looked at the Goff website, and the 5K LED was out of stock.... So just for the sake of it, I bought an H4 LED lamp (OPL5) from an Amazon supplier to fit in my Scrambler's headlight. The connector on the back of the LED is the same length as an H4 halogen lamp, so it doesnt take up space in the headlight shell. The lamp itself is a lot longer than an H4 and the front of the lamp is pretty much touching the inside of the headlight glass. It looks better (from a quick check), it is certainly brighter. The focus of the dip beam is still as rubbish as it was before, but it is a brighter blur. When the main beam is on, the dip is still illuminated, and again the focus of the main beam is as bad as before, just brighter. The main beam warning (blue light) works as it should. In practical terms I think the headlight reflector / glass is more important than the lamp illuminating it. There is an (original) Cibie Z beam reflector in my Norton with an H4 halogen lamp and that is still the best headlight I have used, better than 'modern' bikes I have owned.
 
In 1971 I had a BSA twin with a Cibie (Oscar?) with the concave lens. You could weld with it at 50 yards. Best lamp ever.

You used to be able to get Cibie Oscars as headlamps and auxilliary lamps, The really trick ones had two reflectors and bulbs inside, one dip and one main, and of course it was easy enough to wire them all on together on main beam. I drove a rally car with Oscar headlamps and a pair of the Oscar auxilliaries wired like that on night events....they knew we were coming! Had to be really sure we had turned them off on link sections! Instant exclusion!

This thread could be why he is now out of stock on the 5k bulb.
Have to love an advertising web site that advises " Don't phone me in the evenings- it makes me grumpy"
 
After a couple of months using an LED H4 lamp on my Triumph Scrambler, I have gone back to the Halogen H4.

Two reasons; first and foremost being that it seems that replacing a Halogen lamp with an LED will be an MoT failure.

Secondly, the light output, although brighter, is still an unfocussed blur. Maybe even worse than the Halogen lamp. This is undoubtedly due to the headlight reflector installed on the bike, but the operation of the LED has made it worse.
