Halogen equivalent MR16 Tracklight LEDs have arrived!

Lighting Science Group has done it again, this time with a 12v MR16 tracklight replacement that’s a match for any halogen bulb.

The best thing about these lights is that they only use 8w as compared to their 50w halogen counterparts.   At about $34 each they’re on the low end of the pricing scale as well.

I picked up one of these today to find out if it could live up to the hype.  Remember, 50w Halogen MR16 lights are compact yet incredibly bright light sources as their widespread use in track lights attests.  The challenge is to design a fully compatible, dimmable LED that can produce over 500 lumens at 3000K with a CRI greater than 85.  Finally,  this all has to fit within the considerable physical size restrictions imposed by the MR16 form factor.

Several attempts have been made over the years to solve this engineering problem which is primarily that of keeping the electronics cool enough to produce the desired output.  Up until now, most of the solutions have involved active cooling components which take the form of tiny fans built into the bulb itself.  Definitely not optimal.

Well, I’m here to say that once again, LSG has delivered.  Their Definity HO MR16 bulb is virtually identical to a 50W halogen in terms of color and output.  These lights run much cooler too and can dim all the way to zero using standard dimmers.

The MR16 market is a huge one and I fully expect that Florida based Lighing Science group will make a killing in it.  Today, however, finding one these is a bit difficult.  I purchased mine right here at Earth LED.  I’m saving up for more now!
