A cool way to illuminate procedures

The ACEM Medical Company’s OT - System, which includes the OT-STARLED 7 and STARLED 5, is based on advanced LED (light emitting diode) technology which, the Italian manufacturer reports, ‘…guarantees the best work conditions for surgeons and medical teams in the operating rooms.’

Indeed, LED technology brings several more advantages than conventional halogen and gas discharge bulbs. There’s lower heat generation, excellent colour temperature and an almost never-ending life cycle, for example.

The Starled 7 has 70 LEDs circularly positioned to generate a light spot from 21cm to one metre with a high illumination level and a steady life cycle of 50K hours. It provides high performance illumination for every type of surgery, the firm points out, adding that the lighting includes ACEM’s own intelligent system ACRIS as well as its LIGHT-UP system to enable illumination adjustments according to different applications.

The system produces clear, sharp brightness at 160K lux (self-limited) and a steady 95 (CRI) colour rendering over the time. All of which helps to reproduce the exact chromatic scale of the human body’s colours. There’s also shadows reduction in the surgical field and total illumination of the surface and at depth and, due to obstacle finding sensors, the Brightness Adaptor allows a constant localisation of the head, hands and shoulders of the surgeon. Additionally, ACEM has included its I – SENSE control system, which the company reports is ‘…precise, functional and able to memorise working parameters, which simplifies changes between working modes (standard, automatic, ambient). The central and lateral handles make manoeuvres easy and a standard video camera can be integrated inside the handle in the centre of the light head or positioned on a separated arm. The video recording systems also can be combined with ACEM monitors.


In the firm’s operating theatre proposal the OT-Starled 7 lamp can be associated with the Starled 5. With 50 LEDs, circularly positioned around the handle, a high illumination level of 135K lux (160K lux optional) is generated for a steady life cycle of 50K hours. The illumination is not only focused but also – due to a manual focusing via the central handle of the lamp, uniformally ambient and the exact chromatic scale of the colours of the human body are achieved. The handle can also contain On request, a fixed focus video camera or one with a zoom can be integrated with the handle.


This totally digital lamp is controlled by microprocessors and has a new I-Sense control panel that simplifies regulating and visualising light intensity, ENDO function (light up) as well as light selection – i.e. the use of one, two or all three of its lights. With a simple manual clockwise or anti-clockwise rotation of the handle the light beams can be focused. According to use, this equipment is available as trolley, wall and ceiling mounted - single or double configuration.
