A word of warning here. LED's get a lot hooter then one would think. Stay away from cheap ones as they are a fire risk. We had some, 36 leds with only 4 current limiting resistors. The leds were encased in epoxey. After a few hours of use the resistors started over heating and smoking.
SMD's are better as they usually have a thin aluminum heat sink in the board.
If you go with the raised LED's look for a heat sink on one leg of each LED lead. We have one of this style that is 5 years old now. It was also $70 as a double with 72 LED's
For us two 24 SMD bright white give plenty of light for reading and less heat then the 5 year old one.
