Does anyone have a daylight lamp? Which one and what do you think of it?
I’m thinking of buying an LED one like this and wondered if anyone has experience of them. I want to use it for both painting at night and for photography so it’s important that colours are accurate.
I can’t find anywhere in the spec for that item the colour temperature in Kelvin to establish if it is daylight equivalent or not, you are looking for ~6000K. I have mini sun light bulbs in a ceiling spotlight rail for illuminating displays and they are a daylight equivalent so this lamp might be worth considering

The lamp that I have actually used for photography and working comes from John Lewis (Leo led lamp), it is only 3000K so technically not daylight equivalent but colours come out true and its very nice to work with (the clip base is also very useful).

I’ve been trying to replace the halogen spots in my son’s flat with their led equivalent and have found that they come in either various warm versions - which are quite yellowish - or a cooler daylight version. Have also found the warm varieties to be easier to get hold of and cheaper. Typically (being an artist!) he really really wants the harder to source, more expensive cool daylight bulbs sigh
So just because it’s led, don’t assume it is daylight unless it specifically says so.
Check out the bulbs at iconic lights - they have a range of daylight (and I do mean proper 6500K daylight) LED bulbs so hopefully have the right fittings for you/ your son.

If you’re using the light as the primary light to photograph an object, it doesn’t matter too much what the colour temperature is as long as your camera is set to the same setting as the light. This is called the white balance setting - it’s usually just set to auto but that only works if there is a good bright white object in the scene and can be wrong if you’re photographing some strong colours with no white or neutral greys visible. White LED lamps come in a variety of colour temperatures - some even have a dial to select it but usually they are set to 5000K but beware - some I’ve measured are around 10000K which is too blue for auto white balance to correct on most cameras. If your images are coming out too blue, you might be able to correct it if your camera has a custom white balance setting. If it does, just photograph a plain white surface illuminated by the LED lamp and use this in your custom white balance setting.
Good advice @Imageiseverything thank you. I usually put something white in the shot and adjust the white balance in paintshop pro, so you’re right, all I need to worry about is the extra illumination. I’ve put one of those lamps on my Xmas list 
Not much experience.
I ordered a book lamp from Amazon a couple weeks ago.
