I’ve been using Zoo Med Nocturnal Infrared bulbs for years, put them on a dimmer and you won’t be able to remember when you replaced one last. You get a higher watt then you need, turn it down to the proper temperature. And you prolong the life of the ball unbelievably. No where even close to the humidity sucking CHE heaters that get over 400 degrees easy at the base of the bulb. I don’t have much experience with the RHP’s. But I definitely do with bulbs. Reinz and others will tell you the same (he switched to RHP’s I believe now). Great for tanks, trust me. Hope I offered some help. Good luck regardless.
