The difference between AMALGAM and Standard Output?
Asked : Mar 22, 2018
By : Justin, United States
From the looks of it and a video I found online, the amalgam bulbs have mercury inside of them which increases the efficiency of UV production and allows the units to be higher power at shorter lengths.

Awesome unit

Very well made with a nice count down feature to let you know when to replace stuff.
Not really a con, but be sure you have the room since it is pretty big.
This thing is a well constructed beast, recently hooked everything up and it's running flawlessly with no leaks from the start. I like the count down feature too!!
