The lamp is about 1 cm larger than comparable models (LED, with remote controlled color change) or standard-GU 10 bulbs (halogen), thus it does not fit, for example, in lamp housing, which are completely closed. For my garden spotlights thus unsuitable. There are at half the price of other vendors here at Amazon comparable lamps, which must be appropriate account of their size in the garden spotlights (I have also ordered for comparison). The colored light is used to, the yellow or orange shades look very artificial and not at all pleasant. The white light is not really white, you can see various color shimmer of the three primary colors. The three primary colors red, blue and green are useful, the whole mixed colors rather less.
As fun lighting quite suitable, but by no means a colored halogen spotlight for example in the color to replace yellow. The brightness is also rather insufficient, and the light cone is very small, so a small spot (Felt 10-20 °).
The other LED lamps with color change and remote control here on Amazon as well as make a better light, but it cost only half.
