It's the 42 watt reading light from Lights of America. Keep in mind that these are warm bulbs. Wal-Mart also carries the "cool" bulbs if you need. It's possible that your local Wal-Mart doesn't carry the higher output bulbs. If they don't, they should have plenty of the 20 something watters. Your best bet is to mix some warm and cool bulbs together to get full spectrum.
