The latest LED lighting product to hit Kickstarter, Klauf Light Bars are semi-portable, low-cost LED strips which can be connected end-to-end more or less straight out of the box. They come in 6-inch and 12-inch (15 and 30 cm) lengths, which can be arranged as you like up to a length of 15 feet (or about 4.5 meters). They can either be slotted together directly or connected with cables, which is handy if you intend to install them under kitchen cabinets which extend around a corner (recommended), or make giant illuminating nunchaku (less so).
Usefully, the Light Bars plug directly into a socket. If you're looking for an LED system to install permanently, you might be best off hiring an electrician to escape trailing-cable syndrome, but, if you can see yourself needing to cart your new LED friend between your garage, your kitchen, your garden, and your desk, the semi-portability could be a boon. (In future, Klauf Lighting tells Gizmag it intends to offer 9- and 12-ft extension cables to plug into.) All the necessary electronics are integrated, so there's no hassle with external transformers or DC converters.
Also firmly in the Klauf Light Bar's favor is its warm 2,700-K color appearance, by way of a phosphor diffuser that absorbs light from the high-output blue LEDs inside at one wavelength, before belching it out at another.
And, as much as it pains me to type the words, perhaps best of all is the price. That's right folks, with the temporary starting price of just… Look, seriously, these things are going pretty cheap: $US55 for a 12-inch Light Bar, $45 for the 6-inch (and less, if by some miracle I finish this article in such time that the early bird offers haven't all gone.) There are two finishes: powder black and anodized.
On a cautionary note, though, as LED lights go, these aren't amazingly efficient. The 6-inch and 12-inch models emit 435 lumens and 210 lumens apiece, with a stated efficacy of 50 lumens/watt (though for the 9-watt-rated 12-incher, we make that nearer 48 lm/W). As a very loose comparison, see the 80 lm/W or more of current LED light bulbs. Note that in many cases, those bulb will end up inside a light shade, limiting its performance. Being the complete package, diffuser and all, the Klauf Light Bar has already made its compromises. Still, perhaps efficiency gains will be made in future models, should the product take root.

Pretty good post, A good explanation and specification of led light bars. Today many of us use this lightning system for interior and exterior design.
ReplyDeleteI had no idea that those lights were an LED bar. We have one at home and we use it all the time. It's a little one - not quite the heavy-duty cop kind. It's supposed to stay in my dad's workshop in the garage, but it's really handy around the rest of the house too.
