One of the main stays in Industrial and Commercial Lighting has been the Metal Halide Bulb. It is common in Indoor Fixtures, such as High Bays, Canopy Lights, Garage Lights and Low Bays. It is

So you have a Metal Halide (or even High Pressure Sodium) light, and you want to convert to LED. You’ve done your research, you’ve been inundated with marketing materials that tell you what is the most important thing to consider (coincidentally it probably is something they think is important). And now you are left to make a decision. New or retrofit? What new versus retrofit. We sell both. Our retrofits perform as well if not better than new fixtures, but not all retrofit kits can make that claim. However, if your fixtures are old, leak, and have seen their better days, then by all means replace them. It does not make sense to buy a new fixture that includes a retrofit kit inside of it like some vendors will try and sell you. The engineering of some of the new fixtures are fantastic. However, the real reason you would want to consider retrofitting is because you have a significant investment in fixtures. Why not keep that investment? Retrofitting is extremely cost effective, especially our Look for the DLC Premium Symbol, it’s different than the DLC Standard symbol. And that gives you the quick notification that the light you are looking at is the most efficient.

And why does that matter. It’s simple. It will save you a lot more money. Let me do three comparisons for you. First a retrofit kit designed at 97 lumens per watt to replace a 400W Metal Halide bulb, a second at 102 lumens per watt and ours at 155 lumens per watt. Lets keep everything else the same. Cost of electricity, hours of use. The only thing different you will notice is the watts consumed and the lumens produced. For the record, our retrofit kit uses the least amount of energy in this test BUT also produces the most amount of light. We will use 12 hours a day operating time and .12 kw.h electricity cost

Calculation 1: 97 lumens per watt retrofit head, 135 watts, 13164 lumens

Savings per fixture per year over 400 watt Metal Halide: $170.82

Calculation 2: 102 lumens per watt retrofit head, 143 watts, 14600 lumens

Savings per fixture per year over 400 watt Metal Halide: $166.62

OK, so between the competitor options, you are neck and neck, the difference is so minimal you can make your decision based on whose website you like more

Calculation 3: 155 lumens per watt retrofit head, 100 watts, 15,776 lumens (this is our LED Retrofit Kit)

Savings per fixture per year over 400 watt Metal Halide: $189.22

So there is clearly a $18.40 savings over the first LED retrofit option and a $22.60 savings per fixture over the second LED Retrofit option. And, we produce more light!

We have 3 mini LED Retrofit Kits, 30W, 45W and 60W designed to replace up to 250W Metal Halide. We have 3 standard sized retrofit kits, 75W, 100W and 120W designed to replace from 250 Watt to 400 Watt Metal Halide. We have 2 Large Retrofit Kits, 150W and 200W, designed to provide more light than a 400W Metal Halide up to 750W Metal Halide. And we have 3 Extra Large retrofit kits, 280W, 320W and 350W, designed to replace 1000W Metal Halide.

A good, reliable microwave can be an important part of any modern kitchen. But is your microwave working a little too well? If you’ve got a microwave that just won’t quit, even when the timer goes off, you’ve certainly got a bit of a problem on your hands. But not a problem that our Electricians in Laurel can’t fix! Here are the most common causes for a microwave that won’t stop, and what you should do about it.

There’s some good news to be had here, and some quite likely bad news. The good news is that no matter what folks say, you are not going to be radiated to death by your microwave. They’re generally quite safe, even if they’re running with the door open. However having said that, there are certainly risks, and the problem should not be left alone.

The bad news? The odds are pretty strong that you’re going to need a new microwave, or that replacing your microwave is going to be faster, easier, and safer.

So what causes this problem? There are actually very few causes, which lets us narrow things down pretty quickly. It tends to depend on how and why:

In our honest opinion, you either call in a professional, or you get a new microwave. The door switch is a fairly cost-effective repair if you’ve got a pro, but the panel issue is more complex. And while there are lots of “DIY” solutions out there, videos, mostly, we can’t really in good conscience suggest repairing a microwave on your own. Why? Because a microwave carries a potentially lethal charge, even when unplugged. It’s just not worth the risk!

It doesn’t feel like it yet, but fall is coming! Cooler weather and clearer nights are on the way; perfect time for some home hot tub relaxation. But when our electricians in Baltimore talk hot tubs, we have some concerns. These stem from various issues, but they can all mean one thing in the end: danger.

At Kolb Electric, your safety always comes first. Yes, even before our service (though you might argue that they go hand-in-hand; we would). If you’re considering a hot tub installation, or you’re just getting primed and ready to make use of the one you have, there are some factors we would like you to consider.

Looking for industry-leading electricians in Baltimore for your hot tub or home appliance wiring? Contact Kolb today!

The definition of the word faulty is “working badly or unreliably because of imperfections”, so when we’re talking wiring, faulty can mean old or damaged, or poorly installed. Both of these are equally dangerous and can lead to electric shock, electrocution, and fires! It’s serious business and we aim to help ensure you never deal with these potential threats.

So why are we so worried about hot tubs? Aside from the fact that they’re almost literally giant bathtubs with an electric current, once they’ve been installed many homeowners opt to never have the wiring inspected for water damage or replaced.

And even further beyond, some homeowners regard hot tub wiring as a DIY job. It’s really, really not. Wiring can get complex, and when you’re dealing with something as potentially volatile as electricity (especially when that electricity is surrounded you water!), even the tiniest mistake can become a harmful and even deadly issue.

So how do you get the glorious hot tub you’ve always dreamed of with none of the risks? Do these:
