Good thing they are cheap because you can experiment with them and not cry when they burn up.. The project that I used one of these on was this one:https:// I ran across these flood lights made with the LED lights mentioned in the previous step. CE Approved & Rohs Compliant Details: Emitting Color: Cool White LED Color: 6000K-6500KInput: 110V Lumen: 8000-9000 Lumens Size: 286*237*65mm (L x W x H)Waterproof : IP65 to protect against ingress of dust and against standard water jets with a nozzle Life time: 50,000 hours Lens covered with waterproof material Shell material: Aluminum Now to give you an idea of their brightness --- A set of 2, 48 inch F40 fluorescent bulbs produces about 2,900 lumens. One of these 100 watt LED flood lights produces almost 3 times as much light, 9000 lumen and uses only a little more power to do it. Just one of these lights can replace THREE double bulb florescents fixtures and use 1/3 the power. The timers are designed to NOT keep the lights in sink. Most of the people who have been playing with LED's have tried the long strip rolls. Well, they have adapted that format and started making these little mini strips.For as long as the link stays good, here is an example of these lights. The LED's are mounted and secure on an aluminum back plate that works as a heat sink. So each light eventually is doing its own thing out of time with all the others. I bought the long tube ones as I thought it would produce a greater sense of motion. Most of them run on 12 volts and are being made to be used in cars. The black amber light strip can be used as running lights on a car or a trailer.
Apparently the machines they use are fitted with groups of needles, usually at least three but often five to seven or even more. Regular LED's work great for accent lights and things like that but not reading lights, not kitchen lights. Maybe I am just spoiled, used to all of those glowing orbs pouring forth lumens. I knew they were out there somewhere, but they were elusive and being hard to find.This is the design: For the curious, this is an Alien Technology's European model Gen 1 Squiggle RFID tag.It's actually copper in color and about six centimetres long.
