I replaced my halogen 15w GU10 bulb with this baby and never looked back! Incredibly impressive output. Soft, clean, bright... I couldn't read at night with the bulb that came with the wall lamp I purchased at the store. It was just bright enough for me to poke around the room at night... I would have to turn on the TV in order to see well enough to do/locate anything in the dark. I got tired of using my LED flashlight to read before bed. Inspired by the output of the LED flashlight, I went to the store to find an LED version of the bulb I needed to replace the halogen... nothing could be found to replace it as apparently the GU10 is the "mini" version of the bulb style... and to add insult to injury... the stores only carried "pin" versions. even went to professional lighting suppliers in the area and there was nothing. I found MiniInTheBox online and couldn't believe the availability AND amazing low prices. I took a shot and bought only one bulb just in case it either didn't work or arrived broken during shipping. Delivery was not immediate, but the bulb and cost more than made up for that!!! Unbelievable! I am hooked and am looking to replace every bulb I can in my home and office. The output is stunning and my electric bill is pleasant for the first time in years! Thank you so much Mini... you so rocked it for the every day person!
