i know this is about the reeflux 10k bulb, but i thought id post a comparison pic of my 4 month old XM 15k and my new CV (regular) 14k. just as much if not more color with the CV and considerably brighter. BTW, changed because i have had 2 of the 3 XM bulbs i bought 5 months ago crack or just quit working. just cant afford to replace bulbs that often! it isn't quite that blue in person.
