7.4VDC 5W 1,000 Lumnes with 5 CREES $50.

[KCvale]

Got an old style bullet light with crap lamps in it?
This Retro Army themed Felt with a 4-stroke does and I am wiring up some REAL light for it.

This is the bullet light.

The diameter of the reflector is just under 3".

Now check out this flashlight which also has a reflector just under 3" wide.

And check this one out for $43![/size=4]

In short forget those $500 LED bicycle lights, you can REALLY light the road for cheap.

One other note...
Those Lithium Ion batteries aren't cheap and the retail price on them vary like crazy!
For example my local Batteries+ wanted $14 EACH for them, I bought a PAIR with the light for $6! Hence why my 1,000 Lumens light is only $50.

Honestly I'm using a 15 dollar Cree flashlight and just one of them lamps does the trick.

 

[bowljoman]

Cree's rule! I used two head lamp lights @ $15 each from the local hardware. The came with giant heat sinks and work while directly connected to my front wheel generator hub. They RIP.

Where did you get your light from? I really need some bright light when riding at night due to the fact that some street lights arent working and ive had some close calls.

Those Lithium Ion batteries aren't cheap and the retail price on them vary like crazy!

All laptop batteries consist of 18650 li-ion 3.6v 2500-3000 mAhr. battery pack can be easily built for lights,

I use these under 60 buck and is't perfect small, various Voltage out puts and long lasting

Charger 20.00

last for weeks only powering LEDs. 2 triple cree xm-l T6 head lamps I built. If the specs are right it should be about 5000 lumens. I would honestly never build these again as they are just way to bright for everyday city use. THey stay on low unless I'm showing'em off.

Re: 7.4VDC 5W 3,600 Lumnes with 3 CREES $50.

SUCCESS!​

I just finished my first custom retro bicycle headlight and it is just flat awesome for ~$60.

The retro bicycle light was nothing, it originally came with 2 flashlight bulbs and ran on a pair of AA batteries.

I pulled the reflector with 3 high power CREE LED's that pump out over 3,800 Lumes from this flashlight:

...And fit it inside the original lamps reflector with a little fancy cutting and managed to wedge in a pair of 3.7V Li-Ion batteries to make this.

This is the old style bullet with new flashlight head in it.

This in the same position turned on.

It completely washed out my cameras ability to see any other light than the bulbs.

To emphasize just how bright it is, it's mid-morning, I have sunlight coming into my shop from a window and big sliding glass door, and that ceiling light has a pair of 100W incandescent bulbs in it.

Yes, that is the beam above and brighter than the ceiling lamps in a lit room from 15' away. It even washes out the softer yellowish light on the ceiling on the way there!

Not bad for ~$60 including the Li-Ion batteries ehhh ;-}

 

[KCvale]

Here is how the light turned out on the bike.
Note I pushed the front bag in so you can see better.

These little 18650 3A lit batteries are pretty cool.
Did you know each one has a circuit built into the minus end?

They also like to be charged individually.
With RC and laptop battery packs they obviously can be charged in series, from what I read they have to do some tricks like charge, then drain some, charge again, etc.

For this Army Felts light I just ran a wire out of the light to a plastic battery clip that stows in the front bag.

Also in the bag is the little dual cell wall charger and a fresh set of batteries.
It's a breeze to swap batteries and with the little charger you can charge the other set away from the bike anywhere you have an outlet.

 

[Velodrome]

I beleve thats a "protection" circut on the end to stop runaway dischage in the event of a short hopefuly to keep the bat from overheating and blowin up... Nice job on the light and battery set up! And NICE FELT ! Did you do the camo or did it come to you like that?

 

[KCvale]

Did you do the camo or did it come to you like that?

No I didn't paint it, in fact this bike had a long history before it even got to me.
http://kcsbikes.com/topic.asp?TOPIC_ID=329

In short this guy had been trying for a year and half through 3 different builders to make it go before it came to me.
The initial problem was easy to see, the rear sprocket was mounted inside the outside of those 2 1/4" tires and no straight path to the motor sprocket and the other guys just tried to force the chain to go around.

Anyway, once I finally got the back wheel rebuilt, motor mount set and such other things came up like the front drum and such so I pretty much just rebuilt the thing and awaiting pickup, I just didn't paint it ;-}
