TM1814 RGBW LED Strip Specification: What 84 LEDs/m Does and Does Not Tell You
An 84 LEDs/m RGBW strip can look dense on a sample but still be ordered with the wrong white channel, control grouping or protection construction. This guide turns the published DC24V, TM1814 and IP20/IP65/IP68 options into a procurement decision.
Start with the white light the project actually needs
RGB can mix a pale colour, but an RGBW strip adds a dedicated white channel. That matters when accent lighting must alternate between saturated colour and a usable white scene without relying only on RGB mixing.
The page does not publish white CCT, CRI or luminous output. Approve the required white appearance against material samples and a signed physical sample; RGBW alone is not a colour-quality specification.
Use 84 LEDs/m as an optical clue, not a pixel count
Dividing 1000mm by 84 gives approximately 11.9mm nominal LED pitch. In a shallow profile, that density can reduce visible dot spacing compared with a lower-density tape, but diffuser depth and transmission still control the final line.
TM1814 control grouping is not published on this page. LED density therefore cannot be converted into controlled positions, controller load or cutting length without the supplied circuit drawing.
Do not calculate current from missing power data
The page confirms DC24V but does not publish watts per metre for this version. A current figure derived from another TM1814 strip would be an invented specification, so power-supply and cable sizing must wait for the confirmed production sheet.
For layout, the page lists a 1m standard length and 5m roll or customized packaging. Packaging length is not a guaranteed single-feed distance, continuous run or cutting interval.
Once power per metre and cut grouping are confirmed, calculate each zone from installed length, add the project's electrical margin, and verify far-end voltage under a representative RGBW scene.
Freeze TM1814 control before selecting the controller
TM1814 identifies the pixel-control family, but this page does not publish data timing, controlled grouping, colour order, backup data line or maximum cascade count. Do not infer those details from a different strip using the same IC name.
Use a production-intent sample to verify data direction, pixel grouping, R-G-B-W order, connector pinout and controller output. Save the accepted test file and wiring photograph as order records.
IP20, IP65 and IP68 change the mechanical system
The page offers IP20, IP65 and IP68 options. IP20 suits protected dry locations; sealed versions add material around the tape and can change dimensions, bending behaviour, heat transfer, cutting and connector treatment.
The product image for one sealed construction shows a 10mm tape inside an approximately 13×4mm sleeve. Confirm the exact cross-section for the ordered protection version before selecting profiles, clips or routed channels.
Specification decision table
| Project condition | What to freeze |
|---|---|
| Shallow visible profile | Mock up the 11.9mm pitch with the actual diffuser before approving dot-free appearance. |
| White scene is important | Freeze CCT and visual reference; RGBW does not specify white quality. |
| Dry protected furniture | Evaluate IP20 and retain ventilation and service access. |
| Splash or outdoor exposure | Choose the confirmed sealed version and validate end and connector sealing. |
| Long decorative run | Obtain W/m and cut grouping before calculating feeds or controller positions. |
| Existing controller | Verify TM1814 timing, grouping, colour order and pinout with a sample. |
LIKELIGHT case: freeze a version, not just a product name
LIKELIGHT L-S-10084-TM1814-10MM is published with DC24V, 84 LEDs/m, TM1814, 120° viewing angle, 1m standard length and IP20/IP65/IP68 choices. It is relevant to programmable RGBW accent lines where close emitter spacing and a dedicated white channel are useful.
It is not suitable for purchase from the title alone when white quality, power, cut grouping or sealed dimensions are critical. Freeze those items on the sample and production sheet before approving profile, supply and controller quantities.
| Model | L-S-10084-TM1814-10MM |
|---|---|
| Control | TM1814; final grouping and pinout require confirmation |
| Electrical | DC24V; W/m not published on this page |
| Density | 84 LEDs/m; approximately 11.9mm nominal pitch |
| Optical and length | 120°; 1m standard length; 5m roll or custom |
| Protection choices | IP20 / IP65 / IP68; confirm final cross-section |
Inputs required before quotation
- Installed lengths and zone breakdown
- Required white appearance, CCT and reference material
- Controller model, grouping and colour order
- Protection version and exposure conditions
- Profile, diffuser, bend and connector arrangement
- Power sheet, sample quantity and delivery date
These inputs tie optical appearance, white quality, control grouping, protection construction and electrical data into one order version instead of treating 84 LEDs/m as a complete specification.
FAQ
Does 84 LEDs/m mean 84 pixels/m?
No. It states emitter density; controlled grouping must come from the production configuration.
Can the power be estimated from another TM1814 strip?
No. Voltage alone does not establish W/m, and another layout may use different grouping or current settings.
Will 11.9mm pitch look dot-free?
Not by itself. Diffuser depth, transmission, viewing distance and brightness distribution all matter.
Are IP20, IP65 and IP68 the same size?
Do not assume so. Sealing can change the cross-section, bending and termination method.
