Flowlight: High-tech LED lightstick with 11 light modes. Sold individually as shown in the picture. Details: Flowtoys designed the flowlight from the ground up for high performance, combining the latest technology and components with high-impact plastics to create the ultimate LED glowstick. Great for glowsticking (POI & Staffs), performance, martial arts, concerts, bicycling, camping, mood lighting, fashion accessory and urban ninja gear. length=130mm | diameter=23mm | mass=37g w/battery BATTERIES: Each flowlight runs on 1 AAA (not included) at full brightness throughout battery life - does not dim. Please use only rechargeable NiMHs or high quality alkalines. Cheap alkalines will cause your light to last only a few minutes and turn off on impact. On this site you can buy a pack of four AAA rechargeable batteries for a very good price and they can be charged hundreds of times. BATTERY DOOR: If you spin/play with your light exposed (not in crystal cases or tubing), you might want to get an extra battery door in case you lose it. If you're playing with the lights in casing, you most likely won't need it. More info: origins, features, modes
You can get two of these and use your own strings to make a set of glow poi. However we strongly recommend you get the Flowtoys poi set ( strings and soft shells that encompass the flowlights).
