25°–50° CCT Tunable LED Zoom Profile Spotlight

25–50° CCT Tunable LED Zoom Profile Spotlight

The DUNDI CCT tunable LED zoom profile spotlight combines 2700–6500 K adjustable white light with 25°–50° manual zoom for theatres, broadcast studios and indoor stages. Choose DD-PT2550A with a 300 W LED version or DD-PT2550B with a 200 W LED version. Maximum fixture power consumption is 320 W and 230 W respectively.

Both models on this page use intelligent variable-speed fan cooling and the shorter 25°–50° housing shown in the product photos. Adjust colour temperature through DMX or the local rotary control, then set zoom and focus manually at the fixture. The separate DD-PT2550N is a 200 W fanless option with a longer housing.

CCT Tunable Zoom Profile Series — 9-Model Comparison

The series has six fan-cooled models and three fanless models. All nine models offer adjustable 2700–6500 K white light; the zoom range and cooling construction are selected when ordering.

Model code: DD = DUNDI; PT = Profile Tunable (CCT-tunable profile spotlight); 1020 / 1530 / 2550 = zoom range; A = 300 W LED version; B = 200 W LED version; N = 200 W fanless version. Fanless models are available only in 200 W.

The 300 W version uses 44 warm-white and 44 cool-white LEDs rated at 8 W each; the 200 W version uses 44 warm-white and 44 cool-white LEDs rated at 5 W each. Individual LED ratings are nominal and should not be added together to calculate fixture consumption.

CCT Tunable LED Zoom Profile Spotlight Specifications

25°–50° Photometric Reference at 5 m

The published 5 m beam diameter is 2.22 m at 25° and 4.66 m at 50°. Illuminance changes with zoom, throw distance and CCT. Use the DATASHEET tab for the complete distance tables rather than applying one output figure to every setting.

Selecting a CCT Tunable LED Zoom Profile Spotlight

Start with your mounting position and target area. The 25°–50° version offers wider coverage for shorter throws than the 10°–20° and 15°–30° options. Manual zoom lets the operator set the beam width at the fixture; DMX adjusts dimming, colour temperature and strobe, rather than moving the zoom mechanism.

Use warmer white settings when working with tungsten-style stage lighting, or cooler settings when matching a daylight-lit scene. A single fixture can change CCT without replacing the light source. For camera work, test your chosen CCT, dimmer level, shutter speed and frame rate together during setup.

DD-PT2550A provides the higher published output. DD-PT2550B offers lower maximum consumption. For microphone-sensitive installations, consider DD-PT2550N: it is the separate 200 W fanless version, not a fan-cooled fixture operated at a low dimmer level. There is no 300 W fanless model in this series.

For a single fixed white-light setting, compare the 25°–50° fixed-CCT profile spotlight. Explore DUNDI profile spotlights and lighting technology when planning a mixed-fixture rig.

25°–50° Manual Zoom Operation Reference

This existing 300 W profile operation video is a reference for the shared 25°–50° mechanical zoom and focus operation. It is not presented as a verified DD-PT2550 CCT-control demonstration. For this tunable-white model, follow the current USER MANUAL for the 3-channel / 4-channel map or request a live demonstration.

25°–50° Fan-Cooled Dimensions and Weight

The drawing labels L 730 mm, while the datasheet size table lists 77 × 29 × 29 cm. Confirm the required installation envelope before finalizing clearance. DD-PT2550N has a separate, longer housing and different weight.

CCT Tunable LED Zoom Profile Spotlight FAQ

Which 25°–50° models are covered here?

DD-PT2550A is the 300 W fan-cooled version and DD-PT2550B is the 200 W fan-cooled version. Both offer 2700–6500 K adjustable CCT. DD-PT2550N is the separate 200 W fanless version shown in the series comparison.

Can one fixture change from warm white to daylight white?

Yes. Adjust CCT from 2700 K to 6500 K using DMX or the local rotary control. The display shows the selected CCT. This differs from a fixed-CCT fixture, which supplies one colour temperature.

What do the DMX modes control?

3-channel mode provides master dimmer, CCT and strobe. 4-channel mode adds 16-bit dimmer fine control. Zoom and focus remain manual. The USER MANUAL includes the CCT-to-DMX value reference.

Is the fanless version available in 300 W?

No. All three fanless models in this series are 200 W versions with 230 W maximum consumption. Choose DD-PT2550N for a 25°–50° fanless fixture.

Are the iris and gobo holder included?

They are optional. Standard accessories include a diffusion filter and power and DMX connectors. Specify iris, gobo and connection requirements when requesting a quotation.

Where are the specifications and operating instructions?

Open DATASHEET for series parameters, illuminance tables and dimensions. Open USER MANUAL for setup, master/slave operation and DMX control. Each tab includes an embedded PDF and an open/download link.
