When spotting occurs in a profile, it can be due to several factors, not least of which is the depth of the profile and the amount of LEDs per metre.
If you're using a slimline profile with an LED strip of, say, 30-60 LEDs per metre, spotting is more likely to occur. Your options, then, would be to consider a more recessed profile from our standard and professional range, where spotting is minimized, due to the depth of the profile, even if you were using a 30 LED p/m strip. However, this isn't always an ideal option, depending on how much recess room you have.
To lessen the amount of spotting which occurs within a standard profile, you could consider a strip that offers a higher amount of LEDs per metre, such as 240, although there will still be a tiny amount visible, again due to the depth.
The majority of our profiles come with frosted covers, which don't provide enough diffusion to fully eliminate spotting. Our Optic Corner models come with clear covers and these show more obvious signs of the issue.
As always, please consider your depth requirements and even aesthetic needs; spotting can often be a preference too! Also, do fully test your strips and profiles before you install, as it will affect the returns policy later on.
We offer a range of 14 profiles, most of which will behave the same in terms of the amount of spotting they produce. Therefore, in order to help you decide what profile is right for you, below are sample photos for our 3 main types: Optic Corner, Recessed and Standard (slim recessed):
