See better at night when you use red lights! Or at least, that's what studies say. Red light has the slowest wavelength of any visible light, and can help preserve night vision. So light up in red and try it out for yourself. If nothing else, you'll have a great light color theme, and be ready for any holiday that comes - Independence Day, Memorial Day, Valentine's Day, and Christmas! The bulb's frosted finish diffuses light, creating a beautiful glow with soft light effects.
