Fanless LED Fresnel Spotlight for Broadcast & Studio
The DUNDI fanless LED Fresnel spotlight is a fixed-CCT fixture for broadcast studios, theatres and production spaces where cooling-fan noise is a concern. The DD-S56BN provides 5600 K daylight, while the DD-S32BN provides 3200 K tungsten colour temperature. Both models use 88 single-CCT LEDs, each rated at 3 W, with maximum output power of 230 W.
Passive cooling eliminates the need for a cooling fan. A 12°–60° motorized zoom lets the operator adjust coverage through DMX512 or the local rotary encoder. High colour rendering, RDM support and fine dimming make the fixture suitable for permanent lighting grids and controlled studio setups.

LED wattages indicate nominal ratings per LED, not actual fixture power consumption.
This series includes 11 models: two full-color, three tunable-white and six fixed-CCT versions. Fan-cooled and fanless versions have different housings and dimensions. Exterior images may be shared within the same cooling version; rear labels and controls vary by model. Refer to the relevant model datasheet for LED source, power consumption and detailed specifications.
Model code: 56 = 5600 K; 32 = 3200 K; B = 230 W maximum output; N = fanless. Select the required fixed colour temperature when ordering. These are separate models, not a tunable-white fixture.

Lighting for Noise-Sensitive Production Spaces
A fanless LED Fresnel spotlight removes cooling-fan noise from the lighting setup. This is useful when fixtures are installed near microphones or above a small recording area. For interviews, news desks, spoken-word recordings and theatre dialogue, passive cooling gives the technical team one fewer source of mechanical noise to manage.
Choose DD-S56BN when your lighting plan calls for a fixed 5600 K daylight source. Choose DD-S32BN for a fixed 3200 K tungsten source. Compare the luminous flux of each version and use the shared datasheet’s model-specific photometric table to plan coverage and throw distance.
The motorized zoom changes coverage from a narrow 12° beam to a wide 60° beam. Use the barn doors to help control spill around the subject or set. The fixture remembers the last-used zoom position after power-off, which helps retain an established setup when the system is powered on again.

The fanless housing differs from the fan-cooled version. Use this product’s gallery to review its exterior, and refer to the shared datasheet and user manual for version-specific installation information. Allow clearance for airflow around the passive heat-dissipation surfaces and for the optical assembly to extend as the beam narrows.
Fanless LED Fresnel Spotlight FAQ
Which models are covered by this page?
This page covers DD-S56BN at 5600 K and DD-S32BN at 3200 K. Both have 230 W maximum output power and fanless cooling. For other versions, see the fixed-CCT Fresnel product family.
Does fanless mean the fixture has no cooling fan?
Yes. These BN models use passive cooling. This removes cooling-fan noise; it does not imply that motorized zoom movements are silent. For a sound-critical installation, request a live demonstration under your intended operating conditions.
Can I switch between 3200 K and 5600 K?
No. Each model has one fixed colour temperature. Specify DD-S32BN for 3200 K or DD-S56BN for 5600 K when requesting a quotation.
Which documents should I download?
The DATASHEET and USER MANUAL tabs contain shared DD-S series documents that include both BN models. Read the fanless dimensions and the relevant 3200 K or 5600 K performance data. The manual also provides the 4-channel and 5-channel DMX functions.
DMX and RDM Integration
Use the user manual to select the appropriate 4-channel or 5-channel personality and confirm the channel map before patching the fixture into your console. For protocol background, consult the ESTA published lighting-control standards, including DMX512 and RDM. Request model-specific control information from DUNDI when preparing your installation.
