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! Transparent bulbs allow light to shine from a visible filament, resulting in a highly sought-after lighting effect.
