Tadel» company delivers air conditioners produced in Israel. For certain purposes they required their own trademark based on the Israeli mark Tadiran.

The logo is based on a part of the Tadiran logo, with the Lux suffix and a “propeller” with a letter T added to it, symbolizing one of the main elements of a conditioning system. A neutral typeface was chosen for the word Lux in order to prevent a conflict with the main part of the logo and make Lux stand out in contrast with Tadi.
