Lights in bioactive

My enclosure is 8x3x4ft high with about 1ft bioactive substrate in the bottom leaving 3ft from ground to top. I currently have a 22in glow and grow from biodude thats in the old enclosure. I was thinking about getting 2 jungle dawns from arcadia that are 34in a piece or maybe just getting a 2nd glow and grow. Does anybody know whick is better? I have heard from 1 source that the jungle dawns put off too much heat on there cool side. Maybe their vivarium was only a ft tall, who knows. Out of those two, which do yall recommend, or is there something better that i do not know about?

The JungleDawn fixtures will put out a decent amount of heat but in an enclosure that is 1.2m tall I doubt you will have any issues
