PHILIPS Frameless LED Panel RC468V LED34/9TWH W60L60 GC
PHILIPS 28 W 3,500 lm 3000–5000K UGR <22 Tunable White IP54 front 50,000 h
The only tunable white code we stock on this body: 28 W, 3,500 lm, and a colour temperature that moves continuously between 3000K and 5000K. For interiors where the ceiling has to change character during the day — a warm evening in a showroom, a neutral working morning in the same room. Part of the PHILIPS RC468V frameless panel series, and listed on the PHILIPS LED panel range page.
What 911401904088 Gives You
3000K to 5000K, Continuously
Not a two-step warm/cool switch. The 9TWH code carries two colour channels and mixes them, so any point between 3000K and 5000K is available rather than just the ends.
One Body, No Second SKU
The tunable version uses the same 599 × 599 mm housing and the same 270° edge emission as the fixed-CCT codes. A scheme can specify tunable white in one zone and fixed 5000K next to it without the ceiling changing appearance.
UGR Below 22 at 28 W
Colour tuning does not cost glare control. The 3,500 lm output keeps the same below-22 rating as the fixed 5000K module.
Built for Circadian and Retail Schemes
Warm in the evening, neutral at midday. That is the requirement behind wellness-led office briefs and behind retail floors where the product has to look right under both a morning and an evening setting.
Where This Code Sits in the Range
Tunable white at 28 W. The fixed-5000K equivalent is 911401904070 with a PSU, or 911401904080 with a DALI driver — both are cheaper if the room never needs to change colour temperature. Tunable white only earns its premium when the brief actually calls for it.
The other four codes
| 12NC | Description | Power | Output | CCT | Driver |
|---|---|---|---|---|---|
| 911401904073 | RC468V LED20/950 W60L60 PSU GC | 17 W | 2,100 lm | 5000K | PSU |
| 911401904070 | RC468V LED34/950 W60L60 PSU GC | 28 W | 3,500 lm | 5000K | PSU |
| 911401904080 | RC468V LED34/950 W60L60 PSD GC | 28 W | 3,500 lm | 5000K | PSD (DALI) |
| 911401904574 | RC468X LED42/950 W60L60 FL GC | 35 W | 4,300 lm | 5000K | FL |
All five codes share the 599 × 599 × 58 mm body, the 270° edge emission and the IP54 luminous face. What changes between them is output, colour temperature and driver.

Ingress protection is quoted against IEC 60529: IP20 for the housing, IP54 for the sealed luminous face. UGR values follow the CIE unified glare rating method; see CIE for the calculation basis.
Driver and Control
Driver version on this code: Tunable white — 3000–5000K, two colour channels. The driver is supplied as part of the 12NC, not chosen separately at the counter.
It sits on the back of the module. Panel height is 58 mm on its own and stays under 70 mm once the driver is mounted, which is what lets the module sit inside a standard ceiling void without a spacer.
Where the scheme needs a different control layer, the same 3,500 lm module is available as PSU or PSD / DALI. Driver and system compatibility questions are best answered from the datasheet for the batch you are quoting — ask us and we will send it with the quotation.
Splicing, Mounting and Accessories
Four mounting methods are supported on the same module: integrated ceiling grid, plasterboard recess, rod suspension and spliced runs. Splicing is what the frameless edge is for — two modules butted together read as one continuous luminous plane, and the joint does not need a trim strip to close it. Mounting hardware is ordered as separate accessory codes:
| 12NC | Description | Pack | For |
|---|---|---|---|
| 911401904090 | RC468Z CPC Strip AC Kit | 8 pcs | Spliced runs |
| 911401904091 | RC468Z Profile Clip 4040 AC Kit | 16 pcs | Profile mounting |
| 911401904092 | RC468Z Suspension Clip AC Kit | 16 pcs | Rod suspension |
Accessory quantities in the table are per kit, not per module. Work out kit count from the number of joints, profile lengths and drop points in the layout. The series page carries the dimensional drawing and the full mounting description.
Product Image and Photometrics
One panel, two colour temperaturesThe 9TWH code shifts between 3000K and 5000K on the same module, so the ceiling follows the room through the day instead of staying fixed.
Polar intensity distribution
L.O.R. 1.00 — symmetric in the 0–180° and 90–270° planes. Measured IES, LDT and ULD files are issued with the quotation.
Indicative shape, measured filesThe lobe shows the form of the distribution; the numbers live in the IES and LDT files, so your calculation never runs on a traced scan.
Ordering
| Item | Value |
|---|---|
| Order code (12NC) | 911401904088 |
| Factory description | RC468V LED34/9TWH W60L60 GC |
| Output / CCT | 3,500 lm / 3000–5000K |
| Driver | Tunable white |
| Body | 599 × 599 × 58 mm frameless, IP54 luminous face |
Quote and order by the 12NC. Colour temperature is carried by the digits after the slash in the factory description (940 = 4000K, 950 = 5000K, 965 = 6500K), so a description that looks similar but reads 940 is a different code and a different colour.
Frequently Asked Questions
How is the colour temperature controlled on 911401904088?
From the lighting control system, not from the panel. The driver carries two colour channels and the controller sets the mix, so the CCT that is achievable, and the resolution you get along 3000–5000K, are properties of the driver and controller pair. Confirm the control protocol on the driver datasheet before you specify a controller — we will send the datasheet for the batch you are quoting.
Does output stay at 3,500 lm across the whole range?
Lumen output is quoted for the module, and how it distributes across the 3000–5000K range depends on the driver's channel mixing. Treat 3,500 lm as the nominal figure for the code and ask us for measured data at the specific CCT you are designing to if the scheme is being calculated at the warm end.
Is tunable white worth it over a fixed 5000K panel?
Only if the brief asks for a colour change. A fixed 5000K code gives the same 3,500 lm, the same UGR and the same body for less money. Tunable white pays off where the room has to shift from neutral working light to a warm evening setting — showrooms, hospitality, wellness suites, presentation spaces — and where one ceiling serves both.
