got mine today. The power supply was a dud. Didnt work. Luckily I had another that I had to hard wire in.. The light is more of a blueish light.
Sorry to hear about the dud power adapter, send it back to Amazon and get a replacement, they have always been good about returns.
Are you sure you ordered the daylight LED strip, they also sell coolwhite?
Also, if your over head lights in the printer area are incandescent (yellowish) then daylight bulbs appear bluish because of the difference.
I have replaced my over head light bulbs with daylight balanced bulbs near my computer and printer so everything is lite with daylight bulbs to keep the viewing color constant.
Coming from the commercial photography and offset printing industry years ago, they usually always had a special viewing station set up with daylight balanced light to check prints.
Having ONLY daylight balanced bulbs in my office and printing area allows me to see colors the same and know right away if something is off and there is a color shift.
I think my daylight LED strip is better than using the warmwhite or coolwhite.
