They cast an immediately noticeable brighter, whiter glow. <a href="http://www.ledstrips8.com/outdoor-led-lighting-c-11.html">led outdoor lighting fixtures</a> It’s all part of a citywide upgrade to LEDs that began this summer. A July 2010 press release about the new streetlights explained their expected benefits: <a href="www.ledstrips8.com">led strip lights</a> “We are entering a new era in street lighting,” Superintendent Jorge Carrasco said. “LEDs use 40 percent less energy and last three times longer than the high-pressure sodium lights that have been the standard for the past 30 years. That means better reliability, less maintenance, a longer life cycle, and lower operating costs for our customers <a href="http://www.ledstrips8.com/led-light-bars-c-38.html">12v led light bars</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3720#post-39355 Fri, 26 Aug 2011 10:43:00 +0000 Smudge 39355@http://citycyclingedinburgh.info/bbpress/ <p>@Steveo, where do you get your reflectors/lenses? Is there somewhere europe/uk? The suppliers listed in the diyled site seem to want to charge 30 or 40 dollars to ship a 3 dollar part! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3720#post-39196 Wed, 24 Aug 2011 19:34:12 +0000 ruggtomcat 39196@http://citycyclingedinburgh.info/bbpress/ <p>shoulda asked this while I was still in germany and picked up some cheap ones </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3720#post-39188 Wed, 24 Aug 2011 16:46:38 +0000 wee folding bike 39188@http://citycyclingedinburgh.info/bbpress/ <p><em>accelorometer controlled rear light anyone?<br /> </em></p> <p>B&amp;M already make one.
