PHILIPSST033T G37–30 WCRI 9024° / 36°3-wire 1C
PHILIPS LED Track Light ST033T G3 Series
A display spotlight for retail, showroom and hospitality interiors. Four body sizes from 7 W to 30 W, 3000 K and 4000 K, 24° and 36° beams, white and black housings — 28 order codes, all on COB, all flicker-free, all Class II.

The beam is the product

Merchandise is judged in the first two seconds, and what the customer reads in those two seconds is the beam edge, not the housing. The ST033T G3 is built around that: a lens set deep into the barrel, a textured reflector ring that stops stray light, and a centre fly-eye surface that spreads the output evenly instead of leaving a hot core.
The result is a pool of light with a clean, soft rim — no scalloped edge, no double shadow from the trim, no spill onto the adjacent rail. In a window with three rails 300 mm apart, that is the difference between three defined pools and a wash of glare.
The body also lost its waistline in this generation. One continuous cylinder, a sand-finish shell in RAL9003 white or RAL9017 black, and the PHILIPS mark embossed into the back cover rather than printed on it. Nothing on the surface catches a reflection that would show up in a shop window at night.

Rated flux at 4000 K: 700 / 1,000 / 2,000 / 3,000 lm for 7 / 10 / 20 / 30 W. At 3000 K the same bodies are rated 630 / 900 / 1,800 / 2,700 lm.
Where it is specified
Three interiors, one body
The range is sold into four environments in the catalogue: apparel and furniture brand stores, car showrooms, jewellery and museum display, and hotel public areas. The light levels differ by a factor of three between them, which is why the body runs from 7 W to 30 W rather than a single wattage with a dimmer.
Brand stores and windows
10–20 W in 24° at 2.5–3 m. The narrow beam keeps the pool on the garment and off the rail above it.
Hotel lobbies and lounges
20–30 W in 36° where the ceiling is high and the accent has to reach a reception desk or a corridor wall.
Malls and chain stores
Long track runs on RCS033 2,000 mm sections, I-connectors between them, L-connectors at every corner.
Generation change
G3 against G2
If you have specified the ST033T before, these are the four rows that matter when a schedule is carried over from G2 to G3. The G2 order codes remain online and unchanged.
| Parameter | ST033T G2 | ST033T G3 |
|---|---|---|
| Light source | 7 W SMD; 10 / 20 / 33 W COB | COB across the range, 7 W included |
| Efficacy at 4000 K | above 85 lm/W | above 90 lm/W |
| Power range | 7 / 10 / 20 / 33 W | 7 / 10 / 20 / 30 W |
| Insulation class | Class I (220–240 V) | Class II |
| Power factor | As per IEC | above 0.5 (7–20 W), above 0.9 (30 W) |
| Operating temperature | −20 to +45 °C | −20 to +40 °C |
| Reflector | Smooth reflector ring | Textured ring, softened beam edge |
| Certification | CCC, CB, EMC | CCC, CB, EMC, CE |
| Packaging | Carton | Colour box |
The 33 W G2 body has no direct G3 equivalent — the top of the range is now 30 W. Where a schedule still calls for 33 W, the G2 code stays available: ST033T G2 33W I WB WH.
Design detail
Four decisions that show in the beam
Deep-set lens, fly-eye centre
The lens sits well inside the barrel and combines a central fly-eye surface with an outer scaly pattern. That pairing is what produces a 24° or 36° spot with an even core rather than a bright hole surrounded by a dim ring.
Textured reflector ring
The ring around the lens is textured, not polished. It softens the beam edge and removes the stray patches that polished rings throw onto a wall a metre behind the merchandise.
Driver separated from the body
The driver sits in the track adapter, not in the barrel. Heat from the electronics never passes through the housing, so the metal a customer can touch stays cooler and the LED runs at a lower junction temperature.
Rotation that clears the rail
Horizontal rotation of 0–335° and tilt of 0–90°. The 335° stop, rather than a full 360°, keeps the adapter from being twisted past its contacts against the track.
Fig. 02 — Fly-eye centre, scaled lens, textured ring
What the aperture actually looks like
Under a raking angle the lens reads as three concentric zones: the clear fly-eye core, the scaled ring that spreads the outer beam, and the textured anti-glare ring that catches the last of the spill. There is no visible LED package and no yellow patch at the centre, which is what a customer sees when they look up into a track head at eye level.
Because the source is COB on every wattage, the aperture looks the same on a 7 W body as on a 30 W body. A mixed installation with several wattages therefore reads as one system rather than as two generations of product.

Track system
Track and connectors
The luminaires need a 3-wire single-circuit track. Honnex supplies the matching RCS033 track in two lengths and two colours, plus ZCS033 I-connectors for straight runs and L-connectors for corners. These codes are quoted with the luminaires rather than sold as separate specifications.

Questions
Frequently asked questions
What is new in the ST033T G3 compared with the G2?
Four things change. Efficacy moves from above 85 lm/W to above 90 lm/W at 4000 K. The 7 W version switches from an SMD source to COB, so the whole range is now COB with a uniform aperture and no graininess. Insulation is upgraded from Class I to Class II, which removes the earth requirement on the track adapter. CE is added to the CCC, CB and EMC certification set. The reflector also gains a textured ring that softens the beam edge.
Which wattage should I choose for a retail window or display table?
For a window or a display table with a 2.5 to 3 m throw, 10 W or 20 W in the 24 degree beam is the usual starting point. Use 30 W only where the ceiling is above 3.5 m or the merchandise sits far behind the glass. The 7 W body is intended for close-range accent work at 1 to 1.5 m and is supplied in 36 degree only.
Is the 7 W version available with a 24 degree beam?
No. The 7 W body is catalogue-listed in 36 degree only, in both 3000 K and 4000 K and in both white and black housings, which gives four 7 W order codes. The 24 degree beam starts at 10 W.
Which track does the ST033T G3 fit?
The adapter fits main three-wire single-circuit track, described in the catalogue as 3-wire, 1C. Honnex supplies the matching RCS033 track in 1,000 mm and 2,000 mm lengths in black and white, plus ZCS033 I-connectors and L-connectors for runs and corners. Older two-circuit track is not compatible.
Can I order track and connectors together with the luminaires?
Yes. Track and connectors carry their own 12NC codes and are quoted with the luminaires, so one order line can cover bodies, track and connectors. The connector codes are not listed as separate product pages because they have no independent specification beyond the drawing.
Why do the same wattage codes show different lumen figures for 3000 K and 4000 K?
The 4000 K version runs roughly 11 per cent higher in flux than the 3000 K version on the same body. For example the 20 W body is rated 1,800 lm at 3000 K and 2,000 lm at 4000 K. Quote the figure that matches the CCT you are specifying, not an average.
