Good Quality! But electricity costs high. I bought these lights in September 2011, they are of good quality and maintain very long. However, they are only suitable for short focal length, like me. That's why I do not share them out to LEDs. If the burning time per day at about 2 hours (at 25 cents / KWH approximately 13,14) is, you should be an LED-Spot (zBLighting EVER 5W GU10 LED lamp, bulb, 50W equivalent Perfect Standards size, warm white, recessed lighting, track lighting) to buy.
