I had a financial dilemma a short while ago.
I had hung two Ecotech Radion XR15 Pros over my frag tank using the Radion Premium Hanging kit. See this article for more info.
Now one of my XR15 LED’s was playing up badly and the quoted repair cost was about the same as replacing it with another second-hand unit (which also had the potential to break at any moment).
As this is only for my frag tank, I was unwilling to spend too much.
A little bit of googling and I found a great alternative. A brand new all in one 4 tube T5 fluorescent unit, which cost less than a second-hand XR15 LED.
