It isn't 33% more lighting to achieve the same results. It's some tech telling you how to hang lights and you assuming everything would be the same.
Gavita has told people out here to throw up gavitas on 3 foot centers. It doesn't prove anything. They have the same amount of light, they're the same bulb. It's how you want the throw. The e-pap throws more of it sideways, look at the reflector, doesn't take a mastermind to see that. The
Gavita throws it all down. It's the radiant 8 of double ended hoods. Works great for a lot of people's needs.
The e-pap gets better cross light if both systems are hung on 5 foot centers. It isn't "miraculous". Look in the tent half that epap light is bouncing off the walls. But if there were no walls there that same light would be hitting canopy. Do the same test with four hoods in a 10x10 tent and you'll see different results. The
gavita has hot spots, so much so you have to replace the aluminum reflector. The e-pap doesn't, it runs cooler. I've yet to see multiple hundreds of gavitas hung but i've seen hundreds and hundreds of e-paps in commercial facilities.
