Built by Trinh Hong Phuoc and has been used for 2-3 minutes maximum. Located in the UK, £200.
I originally bought it to burn aiptasia anemones in my fish rank but as this has the beam expander fitted it burns at a further distance than I wanted. It's just sitting in a cupboard unused. Has only ever been turned on a couple of times. Someone may as well get some use out of it. It works very well.Why are you selling?
