Keling KL09L

The KL09L is a ceiling-mounted surgical light for general operating theatres that take a broad mix of cases and need strong, shadow-controlled light over a single table. Surgeons, assistants, scrub nurses and anaesthetists work beneath it through lists that change from day to day.

General surgery is its everyday work. Laparotomies, appendicectomies, cholecystectomies, hernia repairs, mastectomies, and thyroid surgery all benefit from light that reaches the field from nine directions so that the surgeon can lean in and an assistant can retract without plunging the wound into shadow. The focus knob draws the beams together over a deep abdominal cavity.

Obstetric and gynaecological theatres use it for caesarean sections, hysterectomies and ovarian surgery, where the low radiant output keeps an awake mother comfortable, and the colour rendering helps the team assess bleeding and tissue. Orthopaedic and trauma teams use it for fracture fixation, tendon repair, and amputation, while urology teams use it for open procedures on the bladder and kidney.

District hospitals and surgical centres often fit the KL09L as the main light in a general theatre because it covers this wide caseload from one ceiling position. The 280 to 320 cm installation height suits a standard theatre ceiling, and the 280 VA input fits comfortably within a theatre’s lighting supply.

Ceiling mounting keeps the floor around the table clear for the anaesthetic machine, diathermy, suction, and instrument trolleys. Upkeep centres on the 24 V bulbs in the nine reflector chambers, which are replaced as needed so that every source contributes to shadow control.

Light from nine directions

Eight reflectors in a ring and one in the centre light the field from different angles, so a hand or head blocking some beams leaves the others reaching the site.

Beams gathered by a focus knob

The focus knob converges the nine beams on the field, concentrating light on the area and depth the operation requires.

High illuminance

Illuminance rated from 90,000 to 140,000 lux lights deep cavities and fine structures clearly.

Controlled heat in the field

Total irradiance of 600 W/m² or below, with under 6 mW/m² per lux, keeps exposed tissue from drying.

Comfortable for the patient

The patient’s head warms by less than 2 °C during surgery, which matters for awake patients and long cases.

True tissue colour

Colour rendering between Ra 85 and Ra 100 helps the team judge perfusion, bleeding and tissue viability.

Clear floor around the table

Ceiling mounting keeps the light above the team and leaves the floor free for equipment.

Standard installation height

A mounting height of 280 to 320 cm suits typical theatre ceilings and simplifies installation in existing rooms.

Nine-hole reflector head

The round head holds nine reflector chambers, eight arranged in a ring around a central one.

Focus knob

A focus knob brings the beams from the nine sources together on the surgical site.

Illuminance of 90,000 to 140,000 lux

Rated illuminance: 90,000 to 140,000 lux.

4,000–4,500 K colour temperature

Colour temperature is a neutral white between 4,000 and 4,500 K, with a tolerance of ±500 K.

Colour rendering of Ra 85 to 100

The colour rendering index ranges from 85 to 100.

Total irradiance at or below 600 W/m²

The radiant energy reaching the field totals no more than 600 W/m².

Under 6 mW/m² per lux

Each lux reaching the field carries under 6 mW/m² of radiant energy.

Under 2 °C at the patient’s head

During surgical operation, the temperature rise at the patient’s head is under 2 °C.

24 V bulbs

Each reflector chamber holds a 24 V-rated bulb.

220 V ±10%, 50 Hz AC supply

The light runs on 220 V AC at 50 Hz with a ±10% tolerance.

280 VA input power

Input power is 280 VA.

Ceiling plate with horizontal and drop arms

A ceiling plate carries a horizontal arm and a drop arm that suspend the head over the table.

Installation height of 280 to 320 cm

The head is installed at a height of 280 to 320 cm.

Positioning handles

Handles at the head's edge let you move it into position.

The KL09L suits general operating theatres with a broad caseload that want one ceiling light to cover it. Its case is the mechanism: nine reflector chambers, eight in a ring around a central one, brought together by a focus knob so that light reaches the field from nine directions and shadows from heads and hands are filled. Illuminance rated from 90,000 to 140,000 lux, total irradiance at or below 600 W/m², and patient head warming under 2 °C make it suited to long, deep cases. District hospitals and surgical centres with a single main theatre light benefit most. It runs on 280 VA from a 220 V, 50 Hz supply, with upkeep centred on its 24 V bulbs.
