Ugh, 6500K... to me that's not daylight, that's ricer fake HID headlight blue.
Probably not quite that bad but I still really don't like it. Some people do though, but you have to consider what else is around too, if you have other lights and they're a warmer colour the contrast can be very distracting IMO.
I used the Philips bulbs from Home Depot and like them (3000K), they have 35W and 50W equivalent, but they're 2-3 times more than the dx ones.
Lowes carries Cree which I also like as a brand for LED lights, but they don't seem to have them on their website, and I don't know if Cree makes a GU10 bulb.
