Here are my top 3 choices in bedside table lighting........
Keep in mind perspective - with the height and balance your light is need for the space.
1.) A Reading Task Light in any style and space always works. This Lamp is from CB2.
2.) An artistic or unique style lamp in base or in shade. This candlestick lamp is from Anthropologie.
3.) A hotel style lamp will work in most contemporary & traditional style settings. This Lamp style is found at various lighting speciality stores, even Home Sense!
You will never go wrong with a fantastic light design element......
it will always balance and set the mood for your space.
