Keling KL05L.III

The KL05L.III is a mobile surgical light for teams that want strong, controlled light at the table and a lamp that asks little of them between cases. It serves surgeons, obstetricians, anaesthetists, theatre nurses and the biomedical staff who keep theatre equipment running.

Obstetric theatres are a natural home. Caesarean sections need the uterus, bladder and surrounding vessels clearly lit within minutes of a decision to operate, and a mobile lamp that is wheeled to the table and plugged in fits that pace. The patient is usually awake under spinal anaesthesia, and warming at her head of 2 °C or less keeps her comfortable while 80,000 lux lights the field.

General surgery lists use it for hernia repairs, appendicectomies, laparotomies and soft-tissue excisions. Several reflectors converge on the field to keep the wound lit as the surgeon and assistant lean in, and colour rendering up to Ra 100 helps the surgeon distinguish healthy bowel and tissue from compromised areas.

Orthopaedic and trauma teams use it for fracture fixation and wound exploration, and gynaecology and urology lists for open pelvic procedures. In hospitals with more theatres than ceiling lamps, the KL05L.III serves as the main light in an additional theatre or as a second light alongside a fixed one.

Its straightforward build suits district hospitals and surgical centres where one technician looks after a wide range of equipment. With mains operation and a single 24 V, 125 W bulb rating, maintenance is short and predictable, and the four-arm frame keeps the lamp steady in theatres where many people share space around the table.

Little to manage

Mains operation, a single bulb rating and a simple frame keep the lamp easy to run. Staff plug it in, position it and operate.

High output for major work

Eighty thousand lux at 1 metre lights deep and detailed fields clearly through long procedures.

Steady on its feet

The four-arm castor frame spreads the lamp’s footprint wide beneath the pole and side arm, keeping the extended head steady.

Shadow control from converging reflectors

Several reflector chambers aim at one point, so the field stays lit from other angles when one beam is blocked.

Cool at the patient

Warming at the patient’s head can raise the temperature by up to 2 °C during surgery, keeping awake patients and long cases comfortable.

Gentle on exposed tissue

Total irradiance is no higher than 600 W/m², and the lux limit is less than 6 mW/m², limiting the drying effect of radiant energy on an open wound.

Accurate colour in the field

Colour rendering of Ra 85 to Ra 100 shows tissue and blood in their true colours.

One bulb to stock

Every bulb is rated 24 V and 125 W. One line on the spares list covers the lamp’s main upkeep need.

Cold light source bulbs

Keling notes the bulbs as a cold light source.

80,000 lux at a 1 metre distance

At 1 metre, the lamp delivers 80,000 lux.

4,500 ±500 K colour temperature option

Colour temperature is available as an option at 4,500 K, within ±500 K.

Colour rendering index from 85 to 100

The colour rendering index (Ra) runs from 85 to 100.

Total irradiance no higher than 600 W/m²

At the field, total irradiance is 600 W/m² or lower.

Irradiance per lux under 6 mW/m²

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

Up to 2 °C at the patient’s head

The patient’s head warms by up to 2 °C during surgery.

Up to 10 °C across the service range

The lamp’s temperature rise across its service range is up to 10 °C.

24 V, 125 W bulb rating

Each bulb is rated at 24 V and 125 W.

220 V ±10%, 50 Hz mains

The lamp runs from 220 V AC within ±10%, at 50 Hz.

150 VA input power

Input power is 150 VA.

Four-arm castor frame

The base is a four-arm frame with a castor at the end of each arm.

Pole and side arm

A pole rises from the frame and carries a side arm that extends the head over the table.

Multi-reflector head with centre handle

The round head holds several converging reflector chambers and a centre handle for aiming.

The KL05L.III suits obstetric, general and trauma theatres that want high surgical light on castors without a long upkeep routine. Its case is simple: mains operation, one bulb rating, and a four-arm frame carrying a multi-reflector head that delivers 80,000 lux at 1 metre. District hospitals and surgical centres with small technical teams benefit most, as do hospitals adding light to an extra theatre. Warming at the patient’s head of up to 2 °C and colour rendering of Ra 85 to 100 make it a capable lamp for long, deep cases such as caesarean sections and laparotomies. It draws 150 VA from a 220 V, 50 Hz supply, and requiresed is a stock of 24 V, 125 W  as sparesbulbs.
