Does anyone have any suggestions for lights to use while painting? When we moved I turned our guest bedroom into a painting room thinking it would get great natural light because of the large windows. Unfortunately due to the location in the house, I only see about 1 hour of natural light coming in around 6pm and I’m so slow at painting that it would probably take a year for me to finish a project using just that. The light on the ceiling isn’t cutting it and I’ve been supplementing with a little light stand. It’s either not a bright enough light or maybe the angle is not right because when I take my paintings into the sun I can see things I missed that weren’t noticeable with the little light. I’ve been looking for something I could clip to my easel like lights used on music stands but I think the easel sides are much too big for the clip. I’ve considered stealing my husbands shop light, but as he’s working on building a mud room he might not appreciate that 
plus it might be a bit overkill since it’s 8000 lumens.
Lighting recommendations
I went through this exercise a few months ago; and after weighing up all the information, I purchased a good specific floor lamp that met all the specs and now have a great light set-up in my garage studio. I paid $150 for the commercially available (in our town) LED floor lamp that lights-up my resource computer screen, painting, reference photo and palette in 1 go with plenty of light intensity (1300 lumens) of roughly the right colour temperature (5000 K) and Colour Rendering Index (CRI) of 80 that I could position behind and above me so that the light strikes all my working area at the right angle and with no eye strain. A really good time-efficient investment.
Internet searches (around the topic of 'Art Studio lighting') provided a number of good articles by commercial art painters and instructors of how they have set their studios up and the theory behind what is required for best lighting for painting and their choices. Best that you do those searches yourself to understand the background specs for best outcome as there is too much for me to summarise here. Be aware that bulb manufacturers have cut back on the range of colour temperature bulbs on the market, and I couldn't find any now at the 5500 K best recommendation that these painters recommended. Be aware also that the normal bedroom lighting and most desk lamps are around the 3000K warm range that will distort the true colour required in your paintings; and that the loose commercial descriptions of warm, cool, daylight vary between some bulb manufacturers. LED lights are far cheaper to run and last much longer that the other types.
The background fixed lighting in my garage is 2 single 4foot (120cm) LED batten lights, that I have 1 set at 6500K and the other at 5000K. They on their own didn't quite allow me to easily discern the value differences at the lightest and darkest ends of a 10 value grey-scale colour chart without squinting.
The floor lamp I bought is a 'Louie LED Floor Lamp' made by Lucci LEDlux, that has a rotatable LED circular light source at about 6 ft high, that you can easily set (click button) at 3000, 4000 or 5000 K, change the actual light intensity on each of these settings, has a CRI of 80 and outputs 1300 lm. And I can set up my painting desk where I want it without being governed by where the fixed lights are in the room, of cluttering my immediate painting area with a low intensity desk or clamp lamp. Beacon Lighting is a commercial lighting firm that sell this lamp in Australia and they have a many stores in Australia. That should give you some starters for where you are.
My choice is tailored to my ageing eyes, needs, developing passion for painting and hopefully for many years to come; so this was an investment in my future without other constraints and limitations
Thank you for your thorough explanation! Unfortunately that lamp doesn’t seem to be available in the US so I will have to do some digging by looking at those lighting articles. Thanks!
I have a head worn lamp which is elasticated and the light level is adjustable, ok it,s not like natural light but i find it helps in my poorly lit bedroom which is the only bit of space i can find for my set up.
