At first I had 5000K cool white light in my skylight but it was just too bright and bluish. I replaced those bulbs with these 4000Ks and it made a world of difference to me. I can easily work at night and don't have to strain my eyes to read small or faint writing. It's certainly a bright, cool white, but it's perfect for me. I had old lightbulbs there that were so dim and yellowish it was just awful. It might be too bright for other rooms, but I think this bulb would also look great in the bathroom.
