Is it Possible for an Appliance have Drastically Different Power Consumption Levels from a Similar Model?

Currently looking at TVs and stumbled upon this 55inch TCL model that's just right for our budget. I noticed though that a similar TV was being sold on a different store which are practically the same (size, display type, panel, software, I/O, etc.) but the average monthly power consumption dropped from 33kW-hr to 13kW-hr (based on 9hr daily usage).

(models of the TV in question is 55p747, 55P735, 54P635. 55P747 was the one that's exclusive to another store that had the insane power efficiency).

I tried looking at other similar TVs from othwr brands and nothing came close.

How's that possible?

55P747 had a power input of 49W

while 55P635 had 125W power input.

By which criteria do you determine them to be "similar models?"

The 747 has an LED display, while the 635 is LCD. The former will be inherently more power-efficient.

But wait, the TCL site only said it has an LCD Screen Type, and DLED Panel. Which is similar to this other 55inch TV Devant but this one has a power input of 150W. I'm confused again.

Also if the audio is getting 2x9W, that means the TCL P767 is allocating only 30W for the display?

Damn, I thought all of the stuff I've been looking at were LED.

Apparently only this one was LED, that's why.

Won't have doubts now, I'll buy this tclp747. Thanks
