Redsea ReefLed 90 Mount Arm (18"-21") Measurement

[kahjun896]

Hi fellow reefers, wondering if any of you uses the Reefled 90 mounting arm for tanks 18"-21" / 46 -54 cm (width). If possible can you provide me the measure of the arm's length as shown in the picture below ?

I have been using the mounting arm for quite a while and i am suspecting my LFS gave me the wrong mounting arm for my tank size (RS reefer 170).

Please provide the measurements for me as i cant find the actual length of it for comparison online...

Thanks guys for all the help..

The redsea leds? If so I'm using the 50 arms on my 90s. On my redsea 250

hmm, i was told only the 90s arms fit them, but there are 3 sizes...so i need the measurement of the smallest size to make sure that mine is the correct one... The 18"-21" should be just nice for my tank as the website suggests
