How to turn on/off two spaced lamps at the same time?

Question

Do it yourself

There are two lamps, not separated by a partition, but with finished interior decoration, i.e. nothing to drill down. The distance between the lamps is 6-8 meters.
It is necessary to control the on / off of both lamps from one mechanical switch "on the short circuit". Brightness adjustment is not needed, remote control is not needed.
Light sources - LED 12 or 24 V. Load - 0.3-0.7A for each.
Which modules to choose (ZigBee, X10, etc., I have not come across this before) - wireless or via power cable? Which of the most inexpensive, but reliable ones are suitable for these purposes?
From the switch, 220 V comes through a two-wire wiring only to lamp A, plus there is a constant 220 V in both distribution boxes, all this sits in the shield on one machine, i.e. the wiring is unbreakable and without filters.
Place in the distribution box behind the switch: 1.2 x 5 x 5 cm.
Place in lamp A: 3 x 5 x 20 cm,
there are no overall restrictions for lamp B - there is where to hide.

Answer 1

You can try nooLite. Remote control PU 212/312 and two power units. Select power blocks according to the type of lamps.

Answer 2

from simple and relatively cheap - Chinese radio switches. set to one code. buy on dilekstreme.
such a plan dx.com/p/rf-wireless-remote-control-ac-power-socket-white-ac-220v-500w-125068 (you need to make sure that the codes are configured and you can hang both lamps on one code)

Answer 3

from quite inexpensive from the “do it yourself” category, cheap nrf24l01 + radio modules work stably for 30 meters + a controller with minimal piping, but then the brightness adjustment and the remote control will not be a crime against manufacturability . the circuit of both - after all, the wires go there from both lamps - then you won’t need to redo anything anywhere except the shield

Answer 4

It seems that this is what fits: the transmitter is placed behind the switch, and the receiver is placed next to lamp B. At the same time, no additional remote control is needed, it works from the standard switch.
Or such a transmitter and receiver , but you need to re-switch the standard switch.
