The fine people over at LED Group Buy have been busy it seems, working on the Lumia 5.1 multi-chip LED. Many people feel that high power multi-chip LEDs are the holy grail of LED lighting, regarding Kessil as one of the best solutions available with tight chip spacing, high single point intensity, and low color Read More
The Cree XP-E has been the reefing industry workhorse for the longest time (relatively speaking) when it comes to colors outside of white and royal blue, although it has done pretty well in those roles too. Seeing as the white XP-E got a silicon carbide update late last year (which we covered here), Cree felt Read More
Philips, the lighting company behind the Luxeon series of LEDs that are used by a number of aquarium fixture makers, recently announced that they have a prototype LED lamp that is hitting an efficiency of 200lm/W. The 1500lm, 3000-4500K, 7.5W lamp, called TLED, shows us a promising glimpse of what the future will hold for LED lighting. Read More
NEC Lighting Ltd just announced at Light Fair Japan 2013 that it has hit a new industry record for OLED efficiency at 156lm/W. This is trumping the announcement last year from Panasonic for an efficiency of 142lm/W. The achievement was made in collaboration with professor Junji Kido at Yamagata University, where he runs the Kido Lab. This Read More
Cree has been on a tear of late updating their workhorse LEDs to silicon carbide substrates, and while the efficiency gains of LEDs like the XP-E2 and XP-G2 have been incremental, the new XM-L2 takes things to a whole new level. Sporting an unheard of efficiency of 186lm/W @ 350mA (@ 85C), the XM-L2 is Read More
While we are reporting this a few days later, we are happy to see that Cree announced new color options for the XB-D and XM-L series of LEDs on the 50th birthday of the visible light LED. Adding color options to the existing XB-D line-up was not surprising, but the RGBW option for the XM-L Read More
50 years ago today, Nick Holonyak Jr. demonstrated the first visible light LED to the management of General Electric. They were in the race to create an incandescent bulb replacement even back in 1962, but obviously, it’s taken a little longer than Holonyak estimated for that to come to pass. No matter though, as LEDs Read More
As expected, Cree is continuing to upgrade it’s workhorse lineup of LEDs with their new silicon carbide technology by announcing the XP-E2 white LEDs. Much like the XP-G2 before it, the updated LED is showing improvements in overall efficiency and output, while lowering costs Read More
The MakersLED DIY heatsink kits have been out on the market now for a few months, and are getting very well received by the public so far. With a very reasonable price, multiple length options, and a ton of well thought out features, what’s not to like? We decided to take a closer look at Read More
Well, it looks like we jumped the gun a day early with the preliminary announcement of the XP-G2, the successor to the venerable XP-G. Cree has let loose the datasheets for the new LED today, so we can fill in a few gaps in what we know it the little light source Read More
