SparkBright Eclipse

Auto-dimming battery voltage monitors

The Eclipse is a fully waterproof voltage indicator with a bright three colour (green/amber/red) LED. The entire control circuit is built into a tiny water-resistant capsule embedded directly behind the LED, and a black nylon bezel (plus a spare) are supplied for a neat installation into your panel.

Using specially imported LEDs, the Eclipse constantly monitors the ambient light level and adjusts the LED’s brightness, instantly and seamlessly. There is no ‘third wire’ or separate sensor.

You can see a video demonstration of the Eclipse here.

Below are our standard thresholds, recommended for all 12v lead-acid battery systems including an alternator or other charger. Completely bespoke thresholds and output patterns can be created for you at no extra cost (e.g. for custom or ultra-low power applications).


Interpretation:
Voltage: Output: Engine running: Engine stopped (electrics off):
>15.20v Green / Red alternating over-charging – regulator problem not applicable
>13.20v Green steady normal charging exceptional battery charge (uncommon)
>12.45v Amber steady under-charging – alternator problem normal battery, charged and in good health
>12.25v ■■ Red slow flashing not charging – battery low fair battery charge
>12.05v •• Red 2 flashes, repeating not charging – battery low low battery charge
>11.80v ••• Red 3 flashes, repeating not charging – battery very low very low battery charge
<11.80v •••• Red 4 flashes, repeating not charging – battery very low consider renewing battery

* this table reflects a monitor correctly installed as per the instruction guide, and not connected to a high load circuit
(e.g. headlights)
** a small number of users confuse the amber and red colours. However, amber is always steady, reds are always flashing

LED size: Panel hole required for LED bezel: Notes:
10mm 14mm pcb is shrouded by bezel
8mm 12mm pcb is shrouded by bezel
5mm 8mm pcb is connected to LED by 50mm flexible leads
pcb therefore sits outside of the mounting bezel
