Excellent reading light. Good for those who find reading difficult in poor light or find reading text on coloured backgrounds difficult. I bought this light for my Mother who has some deterioration of vision which was making reading of some text difficult with a standard light. I tried the light myself and was impressed with how well it lit up text. Switch on back of main light easily accessible for those who find bending difficult, there is also a switch near the the lamp base. Narrow light beam makes the lamp unsuitable for lighting a room or even part of a room. White light with slight yellow tinge.
