Yeah, it’s part of what helps the “efficiency” of LED lights. I’m using quotes because the portion of the energy savings that comes from what I was talking about in my last message isn’t actually in the LED tech itself, but in the fact that it’s directional. Even LED tubes only have light shooting in one direction (at least all the ones we use) so it’s very important to orient them in the right direction or you won’t be getting the light where you want it (i.e. in the recessed ceiling fixtures the light could just end up going straight up into the ceiling instead of down in the room).
