20 RGB Modules per String: Check 12V Load and Interface
Before ordering RGB modules by the 20-piece string, turn the listed power into a supply estimate and confirm the controller interface in writing. Matching the module alone does not prove it will work with the existing control system.
30-second selection answer
- 30-second answer: The listing identifies 70×12mm RGB modules, 12V DC, 0.96W each, SM16703P and 20 pieces per string: 19.2W nominal per string, about 1.6A at 12V.
- A sensible shortlist when: The project uses a 12V supply and the buyer can confirm controller, pinout and pixel granularity from a drawing or bench sample.
- Stop before batch order if: Protocol, pin assignment or whether each module is independently addressed is not confirmed. An IC name or wire colour is not compatibility proof.
Send the number of strings, supply voltage and controller model for an initial configuration check before sampling.
Decide what the light must do
The listing calls this an RGB pixel module and names SM16703P. If the brief requires colour or animation by module, ask whether each module is independently addressed and which controller/data format is required. “An IC is present” does not establish compatibility.
If the whole run only needs one colour at a time, pixel control may add controller, commissioning and spare-part cost. If independent effects matter, the interface and mapping become acceptance items. Define the visual job before comparing system cost.
Translate the string into a layout
The page identifies a 70×12mm body, 20 pieces per string and 12V. Treat the string as a purchasing and service unit: show string count, connector position and access zones on the sign or display drawing.
Do not derive module count from face area alone. Spacing, orientation, fixing and target brightness affect the layout, and the page does not publish a universal spacing rule. Send CAD or dimensions and request the proposed layout and BOM.
Estimate nominal current before choosing a supply
The title lists 0.96W per piece. For 20 modules, that is 19.2W nominal; divided by 12V, the first-pass current is about 1.6A. This is arithmetic from listed values, not a measured current for every animation.
For several parallel strings, add their nominal loads, then ask the supplier to confirm driver allowance, wire length, injection method and controller output. Keep per-string load, controller-port rating and total supply capacity as separate figures.
Verify pins, data direction and control mode
The scraped page summary mentions a four-pin male/female connector, but it does not provide a verified pinout, protocol or controller list. Red, green, blue and black wire colours alone do not establish data, clock or power assignment.
Before sampling, request the pin diagram, input/output direction, supported protocol/mode, address granularity and recommended controller. For a retrofit, also check connector orientation, lead length and supply polarity, then bench-test one string.
Include environment, fault impact and service
The product title lists IP67. Ask which parts of the supplied assembly that rating covers, including connectors, field joints and site cabling. An outdoor quote should identify connection sealing and how the installer can access a failed string.
A failed module or connector may affect part of a string, but the actual behavior depends on the data path and wiring. The page does not define bypass behavior. During sample acceptance, disconnect one module and observe the rest; use that test to set a realistic spare quantity.
Example: one 20-piece string
Use 19.2W/1.6A to compare per-string budgets; approve a sample or batch only after the interface and supply design are confirmed.
Assume one complete 20-piece string at the listed 0.96W per module and 12V. Driver headroom, wiring loss, scene variation and controller consumption are excluded.

Conditional selection
| Project condition | Buying decision |
|---|---|
| One uniform colour for the whole run | Confirm whether the product/controller supports the needed whole-run mode; compare the cost of pixel control. |
| Animation by module is required | Make address granularity, protocol and controller model written acceptance conditions. |
| Retrofit to existing equipment | Match 12V, 70×12mm body, connector/pins and data direction; bench-test before quantity release. |
| Outdoor or wash-down exposure | Confirm what the IP67 claim covers, including connectors and field sealing; do not extend a title claim to the whole installation. |
Next action
L-M-7012-SM16703P is a candidate for buyers evaluating 70×12mm RGB modules in a 12V system. The page lists 0.96W per piece and 20 pieces per string, enough for a first-pass nominal load check; its title also names SM16703P and IP67.
The IC name alone does not prove controller compatibility. A useful quote should return the exact SKU, module/string mapping, pinout, control mode, supply and wiring, and BOM. Then test a representative string for colour, addressing and fault impact before approving quantity.

| Body / colour | 70×12mm; RGB SMD5050 |
| Supply / listed power | 12V DC; 0.96W per piece (title) |
| Package format | 20 pieces per string |
| IC / page category | SM16703P; described as a pixel module |

Buyer questions
What is the listed load for 20 modules?
At 0.96W each, the arithmetic is 19.2W; at 12V the first-pass estimate is 1.6A. Confirm the ordered configuration.
Does SM16703P guarantee compatibility with my controller?
No. Confirm the exact protocol, pinout, data direction, address granularity and controller.
The title says IP67—what else should I ask?
Ask which supplied components and connections the rating covers and how field joints are sealed.
