We use this for our LED bathroom mirror as a lamp. Before that we had a halogen lamp with 20 Watt. At Amazon, I have seen this savings product consumption with only 2.4 watts and the same order. However, my expectations were not very high, after all, I had concerns about the size and low wattage. After a quick delivery by Amazon a thank you at this point was the same product installed. It is indeed very tight, but it worked without problems! (See photo in the product description)
The only shortcoming is the light color. This was stated with warm white. In reality, however, it is a cooler warm white. The light output is a trail weaker than the halogen lamp.
CONCLUSION: strong buy recommendation from me price, performance and especially the power savings are awesome :)
