NOTE: Headlight Lux rating can be easily computed by dividing Peak Beam Intensity by 100

As ever, your attention to detail makes your videos peerless

I really appreciate level of details you always put in your videos! I ended up returning to the previous one several times when particularly bothered by some subject, like the gearing for example. This video is going to be another one that I will be returning to. Thank you!

An excellent video! Many thanks. It’s packed full of really important information. Every rider should view it.

Thank you for the exceptionally clear overview!

Excellent!! The first clear explanation I've heard of the difference between Lumens and Lux. Thans again!

Very good. The best light I have is an Edelux2 light running off a Son dynamo. I regularly cycle in the complete darkness and this works well. Thanks

Excellent overview! Looking forward to your comparison of the CatEye and other lights. I’m selfishly hoping the former does well, as I own it and the accompanying saddle mounted rear light.

This is what I do to get a nice bright and 'cheap' headlight for my bike: I first get two small 'hose clamps', one just big enough to go around the flashlight, and the other just big enough to go around my handlebars. I then take the two hose clamps and connect them together so that one circle goes inside the other circle. This way they are 90 degrees to each other. I connect one clamp to the handlebars and the other clamp to the flashlight. I adjust them then tighten them up.

Thank you for this really useful and informative video, your channel is a treasure.

i feel like inside the lecture… great video as always 🎉

Something additional to consider: rain at night. On my last night it rained a bit. You'd think the water will make the road shinier, but it somehow darkened the road so that it's harder to see any potholes even with 400 lum. I suddenly have better appreciation for the 800 lum mode.

Excellent summary, thank you!

Thank you so much

I just got the Cateye AMPP 1100 today to replace the 400 lum Rockbros light (200 low/400 high) since the elastic band _just_ snapped after 2 years. The Rockbros was super cheap and managed to last until now, and I had no problems with it except the mount would _not_ stay still if there's any amount of bumps on the road. In my experience, 200 lum was good enough for village/suburb streets, low lights, and slow riding, while 400 lum should be the minimum for any road with serious automobile traffic. I'm gonna appreciate the 800 lum for dark streets or roads without any lights, but a bit overkill for well-lit, maybe even dim roads. I don't see myself using 1100 lum that much. Pity that the AMPP 1100 only goes as low as 400 lumens. Would've stretched the battery life a bit, but I can live with it. Oh, that bit with the battery efficiency with lumens. I _was_ thinking I could've gotten two AMPP 400's instead. Maybe that's why AMPP 1100 has an extra half hour when it's at low/400 lum mode. On the other hand, two... no, three AMPP 400's are equivalent to one 1100 in cost. Tbh I only got the 1100 cause I was going to ride tomorrow haha, but I wouldn't want to carry three lights with me anyway. Also something consider is battery capacity after a couple of cycles. I usually do my long rides in the afternoon, and sometimes 2 hours of light may not be enough, and my Rockbros light was losing its max capacity since it's old by this point, as well as the added degradation caused by discharging it until its empty or almost empty.

Hearing her explanation, I felt like I was on campus again thanks mam

I'm too lazy to count the battery life. So I gave up and joined the dynamo hub party.

I swapped the standard Busch und Müller headlight for one their IQ-XS lights- way better.

you talk too fast
