I’ve tried both the rectangular one and round one. I ordered 18 of the rectangular ones and 12 were yellow and 6 white light.   Wayfair credited me for the 12 yellow ones.  I ordered 16 of the round ones -  I’m happy that the color is consistent white light. However the round ones were advertised as 50 lumens while the rectangular ones are advertised at 8 lumens.  You can see from my photo that there is no difference in the light from each.  I was expecting a lot more light from round ones.  I appreciate if wayfair could rectify the advertising as well as issue a partial credit for the 16 round ones that I purchased.    Thank you.
