10 year warrant seal

Warranty requirements for LED bulbs

Protect your investment in LED lighting by saving your warranty information. If the light bulb fails prematurely you may be able to get a replacement from the manufacturer.

With incandescent light bulbs you are accustomed to the short lifespan, thus don’t give it much thought when a light bulb goes out; you simply replaced it and throw the old bulb away. With LED bulbs you should expect them to last for many years, even in rooms that get regular use. If you do have a LED bulb go out, then it may be covered under warranty. However, if you didn’t save your warranty information and keep good records then you will be out of luck.

Cree warranty statement from LED 60W replacement bulb purchased March 2014

The warranty is an agreement between the manufacturer and buyer. As with most agreements there is fine print. Let’s take a closer look at the requirements for the warranty provided in the example above.

  • Warranty period is 10 years from date of purchase. The parenthetical states “based on 6 hours per day of normal use”. I interpret this as 10 years or maximum of 21,900 hours of use (6 hours x 365 days x 10 years), whichever comes first. Unfortunately, determining the hours of use is, at best, a guess for most people.
  • Used as directed. For this bulb the restrictions are listed on the package under Cautions & Warnings.
  • Return the bulb to address indicated.
  • Include proof of purchase and receipt.

Basically you need to save your proof of purchase (bar code from package), receipt, and failed bulb to submit your warranty claim.

Seems simple enough but in practice it likely will be rather difficult to manage unless you keep very good records to track when each bulb was purchased, the brand and model of each so you can later match it to the proof of purchase, and when and where each bulb was installed.

While a 10 year warranty is good, all said and done, I question if it’s worth the time, effort, and cost. Ultimately the real value in the warranty may be the confidence in the product by the manufacturer.

Thermostat war–Is your room heater fighting with your furnace? Who wins?

Perhaps the better question to ask instead of Who wins? is Who loses? You do. When the furnace and room heater are working against each other, you pay more in heating cost.

To get the furnace and room heaters to work together–and save you money–the thermostat for the furnace cannot be in the same area as the room heaters. The two thermostats will fight with each other and whichever one is set to the higher temperature wins; hint, this is usually the room heater which will cost you more money.

Room heaters may save you money if used correctly. The best use of a room heater is to increase the temperature of the rooms that you use most often to allow the furnace thermostat to be set lower, reducing how often it runs. For example, the furnace can be set to 65 degrees to keep the house at a minimum level and the room heaters can increase the temperature to 68-70 degrees for those individual rooms.  This is great in theory but will be difficult to achieve if your furnace and room heaters are not playing nice with each other.

First let’s talk about your thermostat, because that is what tells the furnace when to turn on or off based on your desired temperature. For furnaces, the thermostat is usually mounted on the wall in one of the primary rooms and can be set to a temperature, such as 68 degrees. For room heaters, the thermostat is built into the unit and may include a display for the temperature setting or simply have a dial or buttons to increase or decrease the temperature.

Scenario #1 – Your furnace thermostat is in the same room as your room heater.

You set the furnace thermostat to 65 degrees. Say you want the living room to be nice and cozy at 70 degrees so you crank up your room heater. Ahhh!  Only now the furnace temperature setting is lower than the temperature of the room and will not turn on, allowing the rest of the house to get cold. Then what happens is the heat from the warm room will carry into adjacent rooms in the house and will try to heat those rooms as well. This causes the room heaters to run more and reduces the money savings.

Scenario #2 – Your furnace thermostat is away from your room heaters.

You again set the furnace thermostat to 65 degrees and use your room heater in the living room to make that room nice and cozy at 70 degree. Because the furnace thermostat is in a separate room, not heated by the room heater, the furnace will turn on when the temperature falls below 65 degrees. The two heaters are working together, providing you with comfort and money savings.


If your scenario is similar to #1 then you may need to consider the following options.

1. Relocate the furnace thermostat to a better location that allows the room heater and the furnace to work together.

  • Keep in mind that during the summer months the furnace thermostat controls the AC and the current location may work well for cooling.
  • Moving the thermostat may leave a hole in the wall that will need repaired.
  • If moving the thermostat is not practical then consider installing a second thermostat at the desired location. The old thermostat can be abandoned or used during summer months only. (Only one thermostat can be connected to the furnace so you will need to have a qualified electrician switch the thermostat wiring at start of each season.)

2. If the room heater is only used temporarily, say only when you have company over, then you may be okay with leaving the thermostat in that room. If the rest of the house gets too cold then you could turn up the furnace thermostat until the furnace turns on and let it run for a few minutes and then turn the thermostat back down.

Note: Installing or rewiring a thermostat requires an understanding of electrical circuits and is best done by qualified electrician.
