Product Description
Product Code: 1230WW We are proud to introduce our all new super bright LED replacement bulb for any standard MR16 application. This bulb works with a 3.7 watt LED to give you 30 degree spot illumination that is comparable to a 20-30 watt incandescent bulb. By replacing your standard incandescent MR16 bulbs with LEDs you will reduce greenhouse gases by consuming less energy. As a result your energy costs will go down significantly as well. This High Power MR16 costs less than $1.00 per year to operate. (cost to operate taken based on national KWH costs, and an estimated 8 hour per day usage). We offer 1 year product on This Product.
Technical Details
- 196 lumens
- 90% more efficient than incandescent and halogen
- Long lasting up to 50,000 hours
- Mercury free/environmentally friendly, no UV emissions
- Resists shock and vibration
MR16 3x1 Watt LED Spot Light Bulb 20W, warm white, 1230WW
Customer Reviews
We had three 35W bulbs and five 20W bulbs for a total of 8 bulbs in our front yard. They were installed by a landscaper, so unsure of brand or reason for varying wattages. These are used in an urban environment for the dual purpose of ornamentally highlighting the home and for adding extra light (security) for passersby on the sidewalk. They aim light up the side of the house, through small bushes and small trees.
Because LEDs are new I just ordered one of these 3W LEDs. I was concerned about color of the light, lumens, and width of the beam. I was also concerned about whether or not this MR16 LED would fit into the landscape light fixtures.
We were unable to tell the difference between the color, lumens, or beam width between this LED and the pre-existing 20W and 35W bulbs. That raises the question of why we can't notice a difference between the 20W and 35W bulbs. After consideration, it's probably the outdoor use and application that makes it difficult to notice. The outdoor lenses are covered in dust and dirt. All of these lights shoot upward toward the house through bushes, trees, or other plants. '
We would, however, perceive a color change. We tried other LEDs inside the home and note that they have a green color compared to incandescents. In contrast, these 3W MR16's (warm white version) have a light color indistinguishable from the 20W and 35W halogens the landscaper had installed - presumably from home depot's lighting aisle.
We'll probably order 7 more of these LED's, which will take our total wattage from 205W to 24W.
The math is pretty interesting on this. Our electric cost is $.11/kwh (from electric bill). These landscape lights probably run about 12hours/day throughout the year (longer in winter, shorter in summer). An online electricity cost calculator says that the current 205Watt MR16 setup costs $98.50 per year. The new 24W LED system will cost $11.50 per year; electric bill savings of $87/year. Amazon is selling these for $12.50, so it's $100 for eight bulbs.
Of course, the number of hours that the old bulbs last is much lower than the expected lifetime of the new LED's, which would be part of a cost-comparison, but that's really an open question. In other words, when CFL's were claiming great efficiencies and extended bulb life, we believed the packages but were disappointed. Some of the CFL's burned out faster than incandescents because we installed them into places with frequent on/off switching. For that reason, we'll just wait to see how this LED makes it through the winter.
I used this product to successfully replace my 50 Watt halogen bulbs which are on a low voltage track light with a dimmer. They are not quite as bright as the 50 Watt halogen bulbs but I had those dimmed 30% so for my application it is perfect. As for dimming, the LED is dimmable but isn't capable of dimming to extremely low light levels like a halogen bulb. The only negative with the new bulbs is that with their riveted exterior makes it somewhat difficult to squeeze them in between the brackets on my track light fixtures.
I did some quick math on my application and because I spend 10 cents per kWh and use the bulbs about 4 hours per day, the new bulbs will pay for themselves in 1.8 years with an IRR of 47%. For my 24 bulbs I will spend $300 and save $165 per year. I'll take that kind of return all day long. This doesn't even include the fact that LEDs will last significantly longer than halogen bulbs or that they emit less heat (which is a factor as I live in Arizona).
