Liftmaster 8550 Vs 8355: Comparison Chart

Differences

1. Motor Power

LiftMaster 8500 has a higher power of 0.75 hp or about 560W. This allows you to use it with more massive doors as well. Although the noise may be an issue. The Liftmaster 8355 model has 0.5 hp or about 370W motor. For light gates, this is a better alternative, as it is silent. On the whole, Lifmaster8500 is more powerful, hence the winner.

2. Driver

The LiftMaster 8500 is driven by a DC motor, while 8355 has an AC motor. This permits more natural speed control with the 8500 model. With the start and stop mode, it gradually starts and ends the motor. This prevents a sudden jerk in the belt while starting, and impact upon closing. This feature may be useless. But it goes a long way in increasing the life of the product. There’s no such functionality with the 8355 model. LiftMaster 8500 is the winner.

3. Battery Backup

The Lifmaster8500 has a battery for backup during a power outage. You can operate the gate even if there’s a power cut. The Liftmaster 8355 model lacks this. If there’s a power cut, you need to open the door manually. So, LiftMaster 8500 is the winner.

4. Mounting

The LiftMaster 8355 is ceiling mount, while the 8500 is a wall mount. The wall mount design significantly reduces the installation hassle. It also minimizes the apparent danger of it falling (unless it’s firmly secured to a sturdy ceiling). Still, it’s the 8500 model that’s the winner.

Similarities

1. Voltage

Both require similar voltage for operation(115V and 120V). You don’t need any extra transformer or such to use these.

2. Drive

Both use belt drives to open and close the doors. Belt drives are much quieter and can absorb shock and vibrations well. This gives you a smooth, noiseless operation. The only noise that you may hear(if at all) would be from the motor. Both provide a lifetime warranty on the motor and the belt. You can use them without worries.

3. Lighting

Both have two 100W lamps for lighting up the area beneath and around it.

4. Connectivity

Both connect using MyQ technology. You need the MyQ app for this.
