Bikeled.net

Has anybody else come across this site? Looks like a decent light but there aren't many details given and I'm skeptical about the lumens rating.

That's the same as the MagicShine light which can be bought from Geoman for about $80. There is a huge thread on it here: Has anyone tried the Magicshine 900 lumen?

Yup, exactly the same light. I have one, it's great, but that site is a ripoff. $85 shipped at geomangear.com FTW.

The URL is a ripoff from bikeled.org

The lumen claims are likely half what they say.

Hm, no, it's the standard Magicshine light, and it's been tested by someone here at 760 lumens or thereabout. Not 900, but not 450 either. Certainly a bargain considering that anything near that from any of the name brands will cost you $400 or more.

My previous light was a Dinotte 200L, which cost me $140, and the Magicshine at $85 makes it look like a pathetic little candle. And the Dinotte didn't come with batteries or charger and didn't have the runtime that this does.

Just don't buy it from bikeled.net

The LED might put out around 750 at 2.8A if they're using a decent bin. I would think 650 is more likely.

Drop 10% for reflector.
Drop 10% for Glass
Drop 20% for heat
Drop 10% for 2.4A drive

Now the 700lm from the seca is measured out the front of the light.

I haven't used either, but the MagicShine @$85 sure seems like a hell of a lot better deal than the Seca @$550. I think I'd miss the $465 before I'd miss the extra lumens...

For most people yes. Just like a Huffy is better value than a Trek. But I ride a Trek.

Do you really feel that's a fair comparison? I sure don't. I'm the type of person who likes quality, and generally I buy the highest quality that I can afford, as I've found not only is it a better user experience, but it's also cheaper in the long run. Bike lights are one exception to this rule as the technology changes so quickly that it just doesn't make sense to pay $550 for a light that is outclassed in a year or two. At least it doesn't make sense to a light geek like myself who isn't a millionaire. Not to mention the cost of battery replacement on high zoot lights.....urgh.

I've bought expensive lights, and now I use a flashlight, and I couldn't be happier. FWIW I use my lights for commuting.

The 760 lumens was ACTUAL MEASURED OUTPUT with a light meter from the MagicShine. None of the stuff you list is relevant.

I'm not sure what you're saying here - you think the light put out by one light is different than the light put out by another one? Honestly, the build quality on the Magicshine looks pretty darn good to me. The only little quibble I have is that I had to add a little tape to the battery pack to be confident of its water resistance. It's possible that it would have been OK without it, but I put it on anyway. If 3 minutes with a little tape saves me $400, I can handle that. Apart from that, the light head, cabling and connectors are all good. I'm sure they could be made better but honestly I don't think it matters. You can make anything better, but at some point there's simply no need.

In that case the measurements are wrong. Where is the link?
The stuff I listed is a general estimate of what should be coming out the front of the magicshine.
Even lupines single P7 light puts out under 500lm.

Magicshine P-7 Headlight Measurement

The guy should know how to measure lumens, given his background.

But regardless of nattering over numbers, the truth is that this is a well-constructed light that puts out PLENTY of light for just about any bicycling activity. People riding technical high speed downhills in the dark might want two on the bar and one on the helmet. For most of us, this is fine.

Even if the more expensive lights put out another hundred lumens, they're still not worth 5 times as much.

Spend the $500 and get 5 MagicShines!!! That would give you a few THOUSAND lumens as well as lots of redundancy. Should be good.
