Some general information on metal halide ballast kits.
These metal halide ballast kits also come with all the hardware you need for mounting because some situations will require a slight remounting. It's not always the case but everything you need is made available in the kit. When you are replacing the metal halide ballast be aware of the tap voltage that you're using and make sure that's correct on the incoming side. There are a lot of wires and that can seem a little daunting, but if you fall the schematic step-by-step, it's a pretty straightforward replacement. Any licensed electrician is going to know how to do this well and can be trusted to get the light working again. We also have quantity discounts if you're ordering over 10 units and we can get those out to you right away as they are in stock. If you're unsure as to what might be going wrong with the HID light fixtures you have, you can always call us and we can probably help you determine what's going on. We've seen just about everything that could possibly go wrong with something like this and have answers whether it be a replacement of the entire kit or maybe just a component. We want to save you money on the lighting costs and sometimes that means saving money on equipment that you don't need. Ballasts can be a tricky thing to maintain as it can be difficult to determine what caused the failure to begin with. But you can be sure that with a metal halide ballast that is old, heat over time does degrade ballast performance. It’s like any electrical component, the enemy is usually heating and that is the case with this type of product. You can know that if the lamp is not lighting, it’s going to be a ballast issue or one of the components that are a part of it. We want to help you determine the least expensive way to take care of the issue. It's important that we help you save money at every turn and we hope that our lighting solutions will help you to do just that.

Ballasts are an essential component.
At, we have a wide variety of metal halide ballast kits including metal halide, high-pressure sodium, and mercury vapor. All of these are in the category of HID lighting and one of the consumable items within that category of lighting is ballasts. There are a number of different things that can go wrong with the ballast over time. It could be something like the capacitor, the igniter or the core and coil itself. With the capacitor, it loses the ability to hold a charge large enough to start the arc of the lamp. Sometimes heat becomes a factor which is typically one of the problems that contribute to a ballast failure. We have all different wattages for various types of metal halide lighting from the very lowest 50 watts all the way up to 1500 watt. Understand that these different ballasts can only be matched with one wattage, they don’t run multiple wattages from the same ballast. Many of you in maintenance or if you’re an electrical contractor know this, but some people that we talk to don’t, so we just want to make that clear if you’re unsure as to whether you need to change the ballast and get one of these kits. Please give us a call or email as we have a lot of expertise in ballast replacement and have probably seen about every different type of problem. Changing a metal halide ballast kit is really not too difficult although there are a lot of wires and there are just a few things you need to make sure that you do correctly. You want to make sure all the wiring is correct and that it’s connected to the correct voltage on the ballast.

Some ideas to save money.
If you have many of these metal halide ballasts going out at the same time, it might be time to consider going to a more efficient source of LED lighting with either a simple retrofit or a complete light fixture change. There’s never been a better time to take advantage of electric utility rebates and the prices on these products that we have have never been more reasonable. The performance is excellent and you could have light fixtures that no longer need a ballast and that’s one less thing to have in a maintenance program. If you would like to know how much money you can save by switching to more efficient LED lighting, we have an free downloadable XL spreadsheet on the left-hand column of our website. It’s easy to use and all you have to do is put in existing data compared to what you might be changing it to. It will not only tell you how much money and energy are going to save, but it will also tell you how fast the payback is going to be for your particular situation. Keep in mind that the more hours per day that you run any of these light fixtures, the faster the payback will be. If there are any electric utility rebate incentives that you could apply, you have a place to put those in as well and that will reduce the payback even further. It’s good time to take a look at that you have an older type of lighting system that you’re doing a lot of maintenance on.
