Fuji Stoots emergency light
Professional Range
This high-end, compact and lightweight emergency lamp can be used alone or in addition to a Tamu or Yeti Stoots main lamp.
Powered by a large capacity easyLock 21 4900 mAh battery, in white light, it provides a constant lighting power of 250 lumens for 13 hours.
Thanks to its fixed or flashing red mode, attached to the seat post of the bike or to a backpack, it increases your visibility for greater safety.
The lamp comes with a metal cord that allows it to be attached to any attachment.

Description:
Ease of use:
A double click at startup is used to unlock our lamps, then a short click increases the power and a long click decreases it.
When starting from an off lamp, a long click allows you to check the battery level through red flashes, then access the hidden modes, as shown in the diagram below:

Technologies:
- the LEDs
Depending on these different parameters, Stoots chooses the LEDs in its lamps in order to optimize performance while primarily providing pleasant lighting. All our lamps have 4000 K LEDs with a CRI of 80, offering you lighting with the most natural rendering possible.
For diffused lighting, Stoots uses different LEDs (wide, medium, narrow) which have around 240 lumens/W.
The spot is based on a 150 lumens/W LED. For this beam, a minimum size of the LED is preferred rather than seeking to maximize its pure power. We thus obtain a very narrow and very clear beam with a greater range than if we had selected an LED with better efficiency but a larger emitting source.
Thanks to these technological choices, Stoots lamps combine comfortable lighting with a light output that can be up to 2x higher than other headlamps in the same category. This explains the excellent weight/power ratio of Stoots lamps. With better efficiency, the battery can be smaller for the same autonomy.
- regulated electronics
The regulated electronics prevent a drop in brightness by maintaining a constant supply voltage for the LEDs, regardless of the battery charge level.
So, for example, a lamp advertised at 200 lumens will be able to provide these 200 lumens throughout its operating cycle.
In practice, a good number of regulated lamps are only partially regulated.
Regulation is active on the first half of the battery, then unregulated on the second half. This is linked to the type of electronics used which does not allow regulation over the entire range of use of the battery.
Stoots lamps feature cutting-edge electronics based on switching architectures.
These PWM (Pulse With Modulation) regulated electronics provide high efficiency (92%) over their entire operating range.
Autonomy is maximized, weight and battery size are limited.
The microcontroller continuously measures the battery's state of charge to provide low-battery alerts during use.
It also controls the lamp from the control button. Finally, all of the electronics have been optimized in terms of size to offer maximum functions and power in very small boxes.
