Product Description

This Bulb is great for replacing your standard 12V Halogen spotlight. The LED Bulb will direct light more accurate instead of spreading the light in any direction and the light seems amazing clean and deliberate compared to halogen or other traditional type bulb. It will last five times longer and are shock resistant. In case you drop the bulb it will likely still work. The bulb will not generate UV and heat so you will avoid burns from touching the bulb. The bulb therefore will not melt your lighting fixture or discolor it. The bulb has a 30 degree spread (beam angle), 4000K color temperature (cool white) and 320 Lumen light output. This bulb have 60 individual LED pieces. The light bulb will unfortunately not work in all 12V power sources and you may have to replace the transformer/adaptor main unit if it has a problem with low load (it may work if you leave one halogen bulb to carry some load). The bulbs application is perfect for home, restaurants, shops, office, etc. Also available in color temperatures warm 2900K and daylight bright 6000K. Note that the bulb is slightly taller than a standard Halogen bulb.

Wattage: 3.8 Verified Purchase
Have been trying various LED replacements for MR16 bulbs for clients. The biggest downfall is that most are not bright enough to convince a client to sacrific brightness for energy savings or less heat production, especially when the bulb price is up to 10x that of a standard MR16 halogen bulb.
Ordered only one of these bulbs as the price was considerably less than many others we've tried and I didn't ant to "waste" $12-$13 on a bad bulb.
This LED bulb (12v 3.8 Watt, 320 Lumen) exceeded all expectations and the clients want more.
Now this item is not currently available and I can't seem to find an equivalent even using the model number.
Love the LED bulb.
Hate that I can't buy 10 more.

1/22/11 Update: Hooray! These bulbs are avilable again! I just placed my order for 10 more :-)

I LOVED these bulbs when I replaced my MR16 bulbs. They were supposed draw very low wattage...They did and were perfect. They were supposed to be very bright...They were and the light they produced was beautiful. They were supposed to last a very long time...Here lies the problem. We replaced a dozen of our MR16 bulbs with these LED bulbs. Two burned out already! It's only been 8 months with (on time) aprox. 200 hours.
What a total let down. We really loved the light they produced. But at the high cost and short life span........
UPDATE 12-2012: The other bulbs are still working perfectly as are the replacement bulbs that the company sent us immediately.
May have just been an unusual fluke.
Still loving the energy savings.
UPDATE 3-18-2013: The original two bad bulbs must have been a fluke. We now have a total of 20 which are still burning bright and hardly using any electricity compared to the filament MR 16's. So we changed our 1 star rating to a 5 star rating.
Final UPDATE 9-5-2015 All bulbs are dead. They produced Great Light; they used a tiny amount of electricity, but they didn't last even a quarter of what was advertised. So, for the high cost of the bulbs, it wasn't worth the money.

I've been waiting for LED lights to take over for the mercury laden CFL bulbs for some time now and it looks like we're almost there. Saying these bulbs are a 35W equivalent is a very conservative estimate I think. I used this bulb to replace a 50W Halogen and I'd say it's almost as bright as that, which is something since it's only using 8% of the power the Halogen was devouring, to say nothing about the incredible amount of heat they were putting out. The only drawbacks are that the bulbs are slightly longer than my usual MR16s so I had to fiddle with the light to fit this one into my existing track lights (but it made it) and the LEDs are closer to daylight at 4000K which means most people will think it looks blue compared to their normal lights. I'm going to try their 2900 K, 300 Lumen bulb LED MR16 Spotlight 12V 3.8W (300 Lumen - 35 Watt Equivalent) Alloy Reflector Halogen Replacement Bulb 2900K Warm since I know it gives enough light to spare and my wife will appreciate the warmer light.

I waited over a year to write this review to ensure I have thoroughly tested these bulbs. In brief, I am VERY HAPPY! I use these outdoors with my landscape lighting. I tested a lot of different MR16 based bulbs in my old halogen fixtures. I tried all different prices, types and colors of LED bulbs in my system before settling in these. I now have about 15 of these in my system running all night every night for over a year. They are long-lasting, low draw and have the perfect light color for proper landscape color. It's a nice, clear, bright white. Not yellow, not blue. Just right.

A quick review to say that I've bought a couple of these 2 months ago.

Light: pretty white, but not so much that you feel like in a hospital. At first, it shocks a bit compared to your regular yellowish incandescent bulb, but I'm not totally used to it and will buy more for the rest of the house.

The bulb does not have a nice smooth surface and is slightly taller than a regular MR 16 light. So, if you look directly at the recessed light, it does not look as great, but I consider this a minor annoyance worth the energy efficiency gain.

Overall: good price for a 12 V LED light that's quite powerful.

I have 2 of these hooked to a 12V battery(charged by some solar panels) I use them to light my living room(med sized apartment) during the night and morning when it is dark. They are bright, and I can see to do anything I need (read, watch tv, eat, crafts). I have them pointed at the ceiling and use the reflected light for ambient. The light beam has a blue spot(1 ft at 1.5ft distance from object) in the center which fades to white. If these were pointed down it would be quite annoying, but shining them on the ceiling makes them work perfectly. Most of the time I can get by with just 1 light, unless I need to read.

Just fabulous, I was skeptical but reading some reviews I was encouraged. Light ouptut is much better than the halogen from look perspective and if you like white-blue look for whitewash. Still don't know if we have realized any savings but I'm guessing it'll appear in our next bill or during winter months when it is comparable.

The only downside is that the bulbs run little taller than regular halogen. I had to manually alter some of the fixtures to accomodate this bulb, and only the ones I could. I still have three fixtures where I can't modify the fixture to accomodate these bulbs and I'm still using halogen bulbs in those, luckily those fixtures are on the side of the building so it doesn't look that odd with white-blue output produced by the LEDs and the yellow light from halogen. I only hope they can make it in the same height as the original bulbs. My other option is to change those fixtures down the road that can't accomododate these bulbs - not sure I want to spend that extra money though. Don't buy these bulbs if you don't mave minimum 1 cm clearance in your current fixture from the bulb surface to the glass surface of the fixture.

One other con or wish - I wish these bulbs were available in bulk packs. They are pretty pricey! But I'm not going to drop
