I found it a bit confusing at first, but then realised it is T5 to LED, so the LED power cable is removed & replaced with this.
Excellent. Simple & now only use one socket.
My boy loves this - he is a rescue and was severely malnourished when we bought him home. Unfortunately because of this he has bad teeth and eating is very hard for him. I have tried countless ways of making life easier for him (blending food etc) but this is the only food he really seems to enjoy and get pleasure from.
Arrived on time and all in good order all the parts were of good quality and the vivarium was well made. Would recommend and use again.
