The listing says this ------------Intense red light of up to 6,000 Kelvin which makes no sense because 6000k is daylight white and not red
Also the listing says
*Please note that these are interior retrofit bulbs and are not road legal for exterior use.------ What is that supposed to mean?
Any colour temperature bulb would work fine just so long as it was bright enough, which these are not.
Tommy the 6000k reefers to the colour temperature of the bulb with 2800k being like a yellow incandescent house bulb 4000 often described as white or cool white and 6000 a blue-er day light white.
