Replacing a 50 watt halogen MR16 lamp with a 7 watt LED MR16 lamp saves $240.00 in energy over the life of the lamp. That’s per lamp. This can add up to some serious savings if you make this switch with all of your existing halogen MR16’s.
Making this switch will also save you the time and labor associated with 16 lamp changes. The rated average life of most halogen MR16 lamps is around 3,000 hours. The LED MR16’s have a rated average life of 50,000 hours. Thus, if you installed a brand new LED MR16 next to a brand new halogen MR16, you would change the halogen lamp 16 times and your LED fixture would still be using the same lamp!!!
The LED lamps throw off almost no heat and will be cool to the touch after hours of use. Whereas the halogens lamps begin producing heat immediately and are hot enough to burn after only a few moments. This heat reduction can lead to lower energy costs associated with air conditioning and reduce the risk of liabilities associated with lamp burns.
LED lamps produce almost zero levels of ultraviolet and infra-red radiation which means that they will not cause illuminated objects to fade over time.
Another advantage of the LED lamp is its environmental impact, using one LED lamp in place of 17 halogen lamps means 17 times less waste material. The LED lamp also contains no hazardous substances, even further reducing its environmental impact.
The Lighting Company offers a wide variety of LED MR16′s at rock bottom prices!!!

If you’re anything like me, you understand why the word math is often followed by the word problem.
Figuring energy savings isn’t such a big deal if you understand that no matter how many steps you choose to take to get there, it really only boils down to:
KILOWATTS SAVED X OPERATING HOURS X UTILITY RATE.
That’s it!
Want an example? I thought you might…Let’s say you have 100 ea. 400 watt metal halides in your warehouse (shame on you, it’s 2010!) and you are considering a 4LT T5 High bay retrofit. You operate 4000 hrs. a year and your utility rate for the year averages out to $.14.
So we have what we need, because you called to ask us what the system watts (the draw of the lamp and ballast combination) were , we’re good to go.
- (458-236) x 100= 22,200 system watts saved
- 22,200 / 1000= 22.2 kW saved (because a kilowatt is 1000 watts)
- 22.2 kW saved x 4000 hrs. = 88,800 kWh saved
- 88,800 kWh saved x .14= $12,432 annual savings!
So I did that in 4 steps. If you’re still confused, or would prefer to do it in ONE STEP…give us a call and we’ll do it for you.
So you’ve installed your new lighting, utility rebate’s in the bank and you’re now reaping the benefits of a big reduction of your energy bill.
So what’s next?
What else is there?
You may want to consider these 3 ways to save even more
1. Install sensors
Adding sensors to your fluorescent lighting will give you your biggest bang for your buck. Installing high bay sensors in your warehouse automatically saves you 45% on your current lighting load according to SCE.
Highbay Sensor rebates through SCE, SDGE and PGE have doubled for 2010. There are also rebates available for installing office sensors. Contact us for details
2. Switch to lower wattage lamps
3rd generation T8 and T5HO lamps are now available. These lamps can save you from $19 to $26 over the life of each bulb. Utility companies are currently offering rebates for switching to lower wattage lamps.
3. Switch to LED exit signs
The average incandescent exit sign cost $56 to run per year. An LED exit sign costs less than $5. After current rebates your net cost is $0.00 (that’s not a typo) per exit sign. Sounds like a no-brainer right? It is.
