Full Spectrum Light Bulbs Reduce Glare & Eyestrain

Noticed 60, 75, & 100 watt Blues Buster full spectrum incandescent light bulbs in a local health food store. Advantages listed on the box were:

• Unlike ordinary bulbs - Blues Buster's special glass filters yellow and brown colors so even when it's grey or dark outside - it's like sunlight in your home!
• Blues Buster's superior quality provides up to 5,000 hours of light - 6 times longer than ordinary bulbs!
• Blues Buster's full spectrum light bulb promotes a natural healthy environment in your home!

Their website also lists reduced glare & eyestrain. Tried a 60 watt bulb in a room that only has one light fixture, next to the computer. I always thought our cat never stayed in this room, more than about one minue, because of the computer. Ever since I changed to the Blues Buster bulb, she stays in the room for hours, directly below the light. Anyone have any thoughts about why she seems to like the light from this bulb? Maybe the reduced glare?

Blues Buster - Shines like the sun!
