Be careful what you wish for.

Personally, the Piko R7 Smartcore is going to be fine for me, if I ever decide to invest. Do you know if a single remote switch will turn on/off multiple lights?

After several days of waiting for the new Lupine Alpha 7200 Lumen head lamp to arrive it finally showed up..!

All your weight saving efforts down the drain. how many grams is it?

trekmogul 

Who ever said a word about weight saving..? Weighing myself less then 150lbs and a decent lightweight bike, I am not concerned at all about the weight of a lighting system...

I have the taillight too. Try it if you haven't yet.

Fake Lumens.

The lighter you and your bike are, the greater the relative impact that weight from a given lighting system will have on your speed.

Lighting fanatics are an interresting bunch. Always fun technology to see in person but riding around here sub 1000 lumens has been more than fine. 400-800 seems to be the sweet spot whether in the country or riding in the city.

I use a 700 lumen Ay-Up light and it is just right.
More than that just requires a bulkier and heavier battery pack to power something that isn't required and not liked by oncoming motorists either.
Especially as bicycle head lights are often not pointing exactly where they should be to prevent unwelcome glare.

All manufactures exaggerate the power of their lighting's output. However, its not just the amount of light that matters but the quality as well. Which is to say its all about the lens. A well focused beam may be more functional that one that is much brighter but scatters all around.

Still, light brightness is going to be limited by law when you're on the road. On the other hand, if you're into trail riding, the more light the better. In any event, I reserve judgement until I actually see that light in action.

does it come with a frying pan attachment to cook food on as your ride ..

Even my Niteride can get to hot to touch. But I'm not going to be holding it. To be fair, its not that unusual.

It says I need 10 posts to post urls when I try to upload the picture of my headlights, but I have 2 30 watt dual LED pods on my trike for headlights, I got sick of cars not seeing me.

mstateglfr 

you are about spending in excess of whats needed or even useful.
if you dont buy for weight, what are you buying for? What else is there from a use and benefit perspective?

why buy those lightweight bikes, lightweight wheels, etc if you arent buying them for the weight saving tech?

I genuinely couldnt care that you have a lighting system, it just made me chuckle that your setup is so bulky when all your other posts feature lightweight products.

rseeker

Good point, there may be a headwind effect with that torrent of photons going out the front. It might be necessary to mount an equally-bright rear-facing red-filtered one to balance out the force. I hope the frame is strong.

I wonder if this will be visible from space?

KraneXL

We will anxiously await post number 10. Or would that be 11? I don't remember.

There are many other reasons, besides weight, to purchase high end lighting systems.

Is that right? Only 150 cycles? That seems awfully low.

Just wait until MEILENSTEIN comes out with some LIGHTWEIGHT dynamo wheels. Then you'll be living the dream.

KraneXL

That can't be right...can it? Imagine if you had to recharge daily?

Kahsyrbag

1 hour 20 minutes runtime at max power, 110 hour runtime maximum, so you have a battery life at constant use of 8.33 days - 687.5 days, I'm guessing that 110 hours is a barely visible light though.

Lupine lights are designed and built with the weight of the light as one of the important points. Don't know if they still show weights on the web pages.
High performance lights allow the high end lightweight bike to be ridden fast at night. Or a long time for long distance riders. Or both together. Just like the high end bike lets you go fast, or longer in the daytime. The programmability, the circuit breaker, the fuel gages. the weight, the quality of the product add value too. My second Lupine light was purchased in 2012 It weighs 360 grams. Maximum power is 2400 lumens. But I bought so I can ride 8 hours at 570, with some 1100 lumens on faster downhills. I use it twice a week, all year round. At freezing it goes down to 7 hours. below 20f is a little worse. That's twice a week maybe missing a single ride a couple of times, say 50 weeks to make a conservative estimate. Twice a week for 6 years. I spend time 50 to 75 miles from home in the dark about once a week. Sometimes below freezing. At that temperature about the same time, but less miles The other weekly rides are 60 or less With only about 1.25 hours in the dark. 50 weeks, two rides per week, is 100 rides x 6 years is 600 recharges. Give or take 100 that's still 500 cycles. The first lupine light was used about the same or a little less for maybe 7-8 years say maybe half cycles to the first HID electrode and about half on the second electrode. The old 8 hour battery started losing run time so I went to the new led light. The new light was $600.
The only time I use full power is when I tell people that on high, my bike light is a little brighter than the car on low beam. I have to show them. Far ahead in
usefulness of any bike accessories I have ever had. A bargain at twice that price. Second only to my two litespeeds in favorite thing owned. Well except Bailey.

The old light works fine with a new battery. It's an Edison 10.The lupine taillight has the best of long range and very wide side visibility. Better than any of the other 30 lights I bought trying to save money, and get something cheaper. Most of the others have a low visibility weak spot at about 45 degrees off of straight behind.

I also spent more than the price of the first headlight trying to save money including DIY. I built quite a few lights. Should have started with the Lupine first and saved money.
Edit - The 500 cycle battery is going out tomorrow, still going. Like the energizer bunny.

It's not force from the photons directly that causes the radiometer to spin. If it were then it would spin in the opposite direction (away from the shiny side since reflected photons would impart twice as much momentum as absorbed ones). Light hitting the black side heats it up and then gas molecules (the bulb is only a partial vacuum) hitting that side gain energy from the warm surface and bounce off faster pushing the black side away. This effect is much stronger than the force caused by the photons striking the vanes.
