People reading along should ask themselves: How bright is 1x brighter?

[kenneth]

1x brighter is an oxymoron, it cannot be 1x as bright and also be described as brighter. 1x as bright means same brightness.

#x implies multiplication (from the mathematical notation of multiplication, ×, which looks like the letter X). 1×a = a.

[BenjiWiebe]

IMO, the 'x' changes it. 1x is 1 x the other number, x meaning multiplication.
