Heine standaard F.O. NT handvat, compleet 3.5V LED

The HEINE Standard LED F.O. insert is compatible with all existing HEINE Standard F.O. handles, regardless of battery version (rechargeable or dry cell). To complete the upgrade/replace existing insert the bottom cap and battery are simply moved from the old insert to the new LED insert. Low battery warning function: When the battery (dry batteries or rechargeable) is partially discharged, the brightness reduces automatically to 33 %. It is still bright enough to intubate (like a 3,5V handle with halogen bulb) but reminds you to recharge the handle soon. The LED in the insert has a working life of 50,000 hours and comes with a 5 year warranty. Usage time with dry cells (2x C/LR6): 2 hours of full brightness + 5 hours with reduced brightness. Usage time with rechargeable NiMh-battery: 2 hours of full brightness + 30 minutes with reduced brightness Usage time with rechargeable Li-ion battery: 5 hours of full brightness + 30 minutes with reduced brightness The white LED light is close to daylight and provides homogenous light with a reference colour temperature of 6,500 Kelvin over the whole examination site with constant electronic control of brightness.
