LEDBL-50 High Brightness LED Shadowless Operating Lamp for Surgical Procedures with 160000Lux

You’re looking at 160,000 Lux from 108 individual LEDs, which gives you a shadowless field diameter that adjusts between 160 and 280 mm on the fly. That depth of 1300 mm is measured from the light head to the surgical site, and it holds steady even when you’re working deep in a thoracic cavity — we’ve seen surgeons push it past that with the 6-joint arm. Color tempearture swaps between 3800K, 4400K, and 5000K, each with a ±500K tolerance, so you can dial in the exact tissue contrast you need without relamping.

The Ra is ≥95 across all three color settings, not just peaking at one, which matters more for true microsurgery than most buyers realize — it’s the difference between seeing fascia margins and guessing. It’s a total power draw of 80W, so your circuits won’t complain even if you stack three lamps in one OR, but what actually surprises people is the 50,000-hour LED lifespan at full brightness. That balance arm uses six imported joints with sealed bearings, and we’ve got units running five years without drift in the suspension — it basically stays put once you position it.

The 8-stage dimming isn’t a slider either; it’s stepped for repeatability because you don’t want drift mid-procedure — each step holds within 5% of setpoint. AC input is 110-240V, 50/60Hz, so it works in older buildings or mobile surgical setups, but power supply has a bleeder circuit so don’t stick your fingers in there once it’s unplugged (check the manual for discharge time, usually 20 seconds or so). The panel is German PC — it’s anti-bullet grade, but it will haze if you use solvent-based cleaners; stick to mild soap and water or isopropyl alcohol wipes.

It’s not suited for veterinary mobile units because the arm has a 10-kg counterweight that’s hard to secure during transport, but for fixed OR ceilings it’s a solid workhorse. We usually have chassis in stock but confirm lead time for the German PC panels — those ship seperately and can add a week or so. Every unit comes with an individual photometric test report at 1-meter distance, but we don’t test every batch at 1300 mm depth because the lab setup is two meters high and a pain to calibrate.

The 8-stage dimming uses a PWM controller at 25 kHz, so it won’t flicker on camera sensors — we’ve seen teams recording neurosurgery with this and no artifacts beyond the usual auto-exposure hunting. Storage-wise, keep the unopened box between -10°C and 50°C, and if it sits in a warehose for six months, condition it at 20-25°C for 4 hours before powering up to avoid condensation on the PC panel. Price varies by MOQ (minimum 2 units orders jump shipping priority), and our company offer a 2-year warranty on the driver board but only 1 year on the LEDs — that’s standdard for solid-state lighting actual usage matters more than rated hours.
