Ideal for photic activation during EEG studies
The Lifelines Photic Stimulator combines the brightness of a Xenon flash with the utility and ease of use of an LED device. The device has an equivalent lamp shape and brightness to the Grass PS33 whilst being smaller, lighter and more energy efficient by utilizing bright light LED technology.
The disadvantages of Xenon tube lamps are well known. They are heavy mains powered devices that are generally very expensive, whilst posing a potential safety hazard to the patient and operator.

The key features and benefits of the Lifelines photic are as follows:
- Small, light and self-contained (only 1 box)
This makes it very much easier to mount the unit on an arm for easy positioning - Efficient
Due to the inherent efficiency of modern LEDs, the unit can utilise low voltage DC as a power source
- No heat
Due to the efficiency, little internal heat is generated. This allows the unit to operate continuously and without the use of a fan. - No noise
This has very significant physiological advantages in that there is no noise-induced artefact in the EEG. - No Safety Hazards
No heat and low power consumption means much simpler regulatory approval
