Hey, I’m going to explain the difference, it’s James Abraham again with warehouse-lighting.com, just wanted to give you a difference of what you’re doing when you’re changing out fixtures in your warehouse. A lot of people call up with the question, “Hey, you know, I’m not sure what to replace it with. I know I want to go with a fluorescent fixture or an LED or an induction.” You know, what I’m going to tell you here is this here is probably my best example of a 400-watt fixture. This is hanging in your factory. It may be aluminum shroud. This one here is acrylic. If we pull it up, you can see that, you know, it probably looks like the one you’re trying to replace. There’s really two ways to do this on the fluorescent side. One is to replace it with a T8 fixture, or I’m sorry, a T5 fixture which is here, or the second way to do it is to replace it with a T8 fixture.What I’m going to give you is, you know, a rule of thumb that we follow here, is if you have a 400-watt metal halide fixture like this, you know, a good rule of thumb is a four lamp T5 will take the place of that after it's been diminished for three years. What I mean by that is after three years, the fixture’s going to lose about a third of its total light, and its total output so if you’re happy with the light level that you have in your facility now, this would be the way to go. You could either go with a four lamp T5 which will give you consistently about the same light level as that metal halide did after the three years, or a six lamp T8. Obviously, a T8 bulb is a little thicker, has a little spread at lower levels. The T5 has a better spread higher up, it pushes more down to the floor, and this is actually a small T5. We’ve got others that are bigger. This is just more of an economy brand. So, to give you an idea, you know, if you’re happy with the light level in the facility you could use one of these two options to replace that fixture. We’re finding that, you know, the T5 is getting to be a little bit more popular, you know, as replacing these fixtures. Just to kind of bring you back up to speed on these, there’s 54 watts per lamp position in this fixture, and 5000 lumen output on this fixture. It’s 32 watts and 3000 lumen output so just to give you an idea here this is going to be a 20,000 lumen output fixture. This is going to be an 18,000 output fixture. Yes, it may be bigger, but it doesn’t pack the wallop of a T5. So, you got to remember this if you want a little bit more light, or this if you’re not so, you know, you don’t want the extra 2,000 lumens. So, again it’s James Abraham with Warehouse Lighting.
