Keling KL05L

The KL05L is a ceiling-mounted surgical light for operating theatres handling major, long cases. Its users are surgeons, assistants, scrub nurses, and anaesthetists in general, trauma, orthopaedic, obstetric, and gynaecological teams.

General surgery theatres use its 80,000 lux for laparotomies, bowel resections, cholecystectomies, and hernia repairs, where the surgeon works deep in the abdomen, and the light must reach the bottom of the wound. Colour rendering up to Ra 100 helps the team distinguish bowel, mesentery, bile and blood, and judge the colour of a resected margin or an anastomosis.

Trauma and orthopaedic theatres use it for fracture fixation, joint surgery, and exploring major wounds. These cases often run for hours, and the lamp’s controlled heat output keeps warming at the patient’s head to 2 °C or less while tissue in the open field stays moist. Several reflectors converging on the field help to keep the site lit as surgeons, assistants and image intensifiers move around the table.

Obstetric and gynaecological theatres use it for caesarean sections and hysterectomies, and urology and vascular teams use it for open procedures that need a strongly lit, deep field. In district hospitals and surgical centres, a single KL05L serves as the main light in a general theatre that handles a wide mix of cases week to week.

Because the light hangs from the ceiling, the floor around the table stays available for the anaesthetic machine, diathermy, suction and instrument trolleys. Upkeep means keeping spare 24 V, 125 W bulbs in the theatre store, so staff fit a replacement between cases if one fails.

High light for deep fields

80,000 lux at 1 metre gives the surgeon a strongly lit field, even at the bottom of a deep incision. Fine structures are seen clearly through long, complex cases.

Light from several directions

Multiple reflectors aim at a single point, so the field is lit from multiple angles. A hand or instrument in one beam leaves the rest of the light reaching the site.

Controlled heat on the patient

Warming at the patient’s head is 2 °C or less during surgery. High output does not build up heat under the drapes during long operations.

Tissue kept moist

With total irradiance at or below 600 W/m² and under 6 mW/m² per lux, exposed tissue loses little moisture to radiant heat.

True colour in the field

Colour rendering between Ra 85 and Ra 100 shows blood, bile, bowel, and tissue in their real colours, supporting decisions about perfusion and viability.

Clear floor around the table

Ceiling mounting puts the lamp above the team. The space around the table is kept for people and equipment.

Head aimed from the centre

A centre handle lets the surgeon or assistant move the head over the field as the operation progresses.

Predictable upkeep

The bulbs are rated 24 V and 125 W. The lamp's main upkeep need is keeping spares of that rating.

80,000 lux at 1 metre

Illuminance at a 1 metre working distance is 80,000 lux.

Neutral white option of 4,500 ±500 K

The optional colour temperature is 4,500 K (±500 K).

Ra 85 to 100 colour rendering

The colour rendering index (Ra) lies between 85 and 100.

Total irradiance at or below 600 W/m²

Total irradiance on the field does not exceed 600 W/m².

Less than 6 mW/m² per lux

The ratio of total irradiance to illuminance is under 6 mW/m²·lx.

Patient head warming ≤2 °C

During surgical operation, the patient’s head warms by 2 °C or less.

Service-range rise ≤10 °C

Over the lamp’s service range, temperature climbs by 10 °C at most.

24 V bulbs

The bulbs are rated at 24 V.

125 W bulbs

Each bulb is rated at 125 W.

220 V ±10%, 50 Hz AC

The lamp is powered by 220 V AC (±10%), 50 Hz.

150 VA input power

Input power is 150 VA.

Ceiling mounting

A ceiling plate anchors the lamp above the operating table.

Horizontal arm and drop arm

A horizontal arm and a drop arm carry the head from the ceiling plate to its working position.

Multi-reflector head with centre handle

The round head holds several reflector chambers around a centre handle used to aim it.

The KL05L suits operating theatres that handle major general, trauma, orthopaedic, and obstetric cases and need high-level overhead light. Its design focuses on output: 80,000 lux at 1 metre from a multi-reflector head, enough to clearly light a deep field for hours. Total irradiance is limited to 600 W/m² or less, and warming at the patient’s head is 2 °C or less, so the field stays moist and the patient stays comfortable. Colour rendering of Ra 85 to 100 supports tissue assessment. A theatre that keeps spare 24 V, 125 W bulbs keeps the lamp at full output, and it draws 150 VA from a 220 V, 50 Hz supply.
