How to Properly Organize LED Lighting in Two Rooms

30 May 2025

Dear friends of the Artled online store, we continue to introduce you to the most interesting questions from our customers.

LED tape for room

Optimal LED lighting in the apartment

Request:

For two rooms with an area of 16 m² and 11 m² we recommend two separate groups of LED lighting for convenient control and uniform illumination of the space.

Connection conditions:

LED strip COLORS COB-24V-IP20 18W 2700+6500K 5m
Two Tuya WiFi controllers: LED controller DEYA CCT 12-36VDC, 5A*2CH (WZS2)

Question from the Client:

Will it be enough power❓
Will it help LED repeater DEYA 12-36VDC, 8A*2CH (EV2)❓

Answer from Artled (Lyudmila):

To answer accurately, you need to calculate the power consumption and check whether the controller can withstand the load. Let's consider everything step by step:

💡 Data about the LED strip:

• Model: COLORS COB-24V-IP20 18W (2700+6500K)

• Power: 18 W / m

• Package length: 5 meters

• Supply voltage: 24V

• CCT type (dual-channel): means that warm and cold light are controlled separately (2 channels)

⸻

📐 Lighting areas:

• Large square – 16 m perimeter

• Small square – 11 m perimeter

⸻

🧮 Total length of the tape:

16 m + 11 m = 27 m

⸻

⚡️ Total power of the tape:

• 18 W/m × 27 m = 486 W

⸻

🔌 Current at 24V:

486 W / 24 V = 20.25 A — this is the total current on both channels (warm + cold).

Since the CCT strip, the power is distributed between two channels (warm and cold). Usually, the maximum goes simultaneously or only to one of the channels.

Approximately 10.1 A can be counted on each channel if both are turned on completely.

⸻

🔧 DEYA CCT Controller 12-36VDC, 5A*2CH (WZS2)

• Power per channel: 5A × 24V = 120W

• Total power: 240W

So:

• For a large square (16m × 18W = 288W) — one controller is definitely not enough

• For a small square (11m × 18W = 198W) — close together, also risky

❌ Conclusion:

The WZS2 controller is not enough for either of the two zones at full load.

⸻

✅ Using the DEYA EV2 repeater (8A*2CH)

• EV2 can expand channels by receiving a signal from the main controller and add power.

• Has 8A × 2CH, that is:

• 8A × 24V = 192W per channel = 384W total

👉 Recommended solution:

1. One Tuya controller (DEYA WZS2) per zone

2. One or more EV2 repeaters to boost power (especially for a large square)

3. Power supplies of appropriate power separately for the controller and repeaters

⸻

🔌 Configuration example:

For a large square (16 m):

• Power: 288 W

• We use:

• 1× DEYA WZS2

• 1× EV2

• Power supply for ~300-350 W

For a small square (11 m):

• Power: 198 W

• You can:

• or 1× WZS2 + 1× EV2

• or 2× WZS2 (but more expensive)

⸻

🧠 Tip from Artled:

WZS2 controllers are only suitable as signal controllers, and it is better to route all power through EV2. This is exactly what these repeaters are designed for — remove the load from the controller, leaving only control.

⸻

🔋 Power supply:

Each EV2 and controller requires a separate power supply, or one powerful one with multiple outputs, 24V with a power reserve.
