PRODUCT REVIEW
CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb
★★★★★
Great artificial sunlight
I bought a six pack of the 5000K bulbs to use in a windowless basement home office. These make the room extremely pleasant to be in all day while working. It feels very natural, which is what I was hoping for. It keeps me from feeling lethargic or claustrophobic. I tried some cheap "full spectrum" bulbs first and they were fairly decent but still felt a little off. In comparison, I can visually tell the others were blue-heavy and lacking something in the yellow/green neighborhood that these Waveform bulbs fill in for a very natural and completely unobjectionable feel."
