This may not be relevant but I have used the MkI version quite close to my 5 x 4 developing trays for some years without fogging film. Quite close is at eye level on the wall directly behind the tray in the wet bench which is just above waist level and about 30" from the timer.
The MkII version is physically identical to the MkI so it's quite relevant! Thanks Les. This is a good time to remind owners of the MkI that upgrades will be available, although the details have yet to be finalised.
