Some people need full spectrum light bulbs, especially in the winter.
Full spectrum lights are available in the CFLs. However, try to find them in the 23W—100W equivalent. I went to Fred Meyer’s, Lowe’s, Walmart and Home Depot looking for them. Fred Meyer’s had them in individual packets, but wanted $4 for them. Lowe’s had them in 4-packs and wanted $8.44 for them. Walmart had a 4-pack but the only pack they had left had broken bulbs inside. Finally, Home Depot had a 4-pack at $1.67! Wow! Full spectrum, 5000K! Those were the ticket!
