If it works as described it will make such perfect stocking stuffers, B-Day gifts for campers, hunters and even for survival usage…No more batteries, white/naphtha gas, butane cylinders...cost saving and environmentally friendly--too cool!
I wonder if they’ll give me a discount if I order twenty or so? I’m going to have to find the manufacturer or distributor…I really like this idea!The maker, quote below, is a company called SOLight
“It is a ”Solar powered water bottle lantern”

From Duluth Pack:
I found this info on the web from a company called SOLight who are the makers of this devilishly good device…This small, lightweight (just 2.6oz) cap fits on any ‘standard’ water bottle (2” wide mouth) such as Nalgene®, Camelbak®, GSI® and most others, turning your bottle into a solar-powered lantern. With clean, green solar energy powering your lantern there are no more burned out batteries to worry about or replace (adding to our already toxic landfills). It is also weatherproof, so don't worry about the elements harming it like they could harm batteries.
Quick Feature Overview
- Fits all standard 2.25” diameter bottles, including Nalgene®, Camelbak® and GSI
- Weighs just 2.6 ounces
- Weatherproof
The LightCap 200 has only been available for a few short weeks, but is already generating lots of buzz in the "blogosphere."
With coverage by more than a dozen major outdoor and environmental websites within the first week of availability, it's already a great hit. Here's what just a few of the bloggers are saying about the LightCap 200:
Create Light ... Not Waste
DON’T THROW AWAY YOUR OLD POLYCARBONATE WATER BOTTLE – TURN IT INTO A LANTERN!
The last thing this planet needs is any more plastic in the landfills. But what do you do with your old polycarbonate water bottle (Nalgene or similar) that you don’t want to use any more? Don’t throw it away! With the incredibly handy LightCap200 you can turn your old bottle into the coolest home, deck, boat or camping lantern anywhere!
Just pull off the old cap and replace it with a safe, bright, environmentally-friendly solar-powered LED LightCap200 and you’ll have light anywhere you want without wasteful batteries, dangerous, toxic fuel, or electric cords.
Put one on your picnic table, deck, out by the BBQ, kids playhouse, bedroom nightlight, car safety light, cockpit light on your boat, camper, tent or anywhere else. Simply fill your bottle with water (even colored water) for a safe lantern that won’t run out of fuel or be a fire hazard. No candles to burn out, and when your bottle is filled with water it won’t tip over if the wind comes up.
The built-in light sensor automatically turns the light on whenever it gets dark, and off when there’s enough light for charging. Or you can click the water-tight switch and turn it off manually. It weights only 2.6oz and you can even use it as a flashlight. The four super-bright, white LEDs provide lots of light.
By adding a LightCap200 cap to your bottle you’re not only creating a useful item, you’re helping the environment. You can even use your bottle to store things: trail snacks, dog treats, fire starting supplies, first aid kit—anything you want to keep safe, floating and dry. And with the LightCap200 on top, you’ve always got a useful emergency light.
