​LED (light-emitting diode) and CFL (compact fluorescent lamp) bulbs, with their low energy use, have become more commonly used as incandescent light bulbs are phased out to improve energy efficiency. 

However, one side effect of LED bulbs is that they can potentially limit the range of garage door opener remote controls used for almost any brand of garage door opener. Technically put, the power supply and circuitry of typical LED light bulbs can produce large amounts of 'noise' thus creating EMI (Electro Magnetic Interference). This can cause disruption in GDO performance.

If you are looking for more range from your Mo-Door (and all other remotes being used) one test you could do is to simply unscrew the light bulbs that are on your Garage Door Opener and see if your range increases. If it does, you know where the range problem lies! 

The light bulbs listed below have been tested by us and are known to NOT interfere with transmission.
