The Fox Halo Illuminated Marker Pole Capsule is a multi-colour marker light that fits onto a marker pole, giving you six colour options: red, green, blue, amber, purple, and white. For the longest battery life, red, green, and blue are the best choices, offering approximately 130 hours of use, while amber, purple, and white provide around 75 hours. The capsule has a standby life of roughly 552 hours (23 days) when switched on but with the LED off, assuming quality new batteries are fitted. The capsule lights can be turned on and off using the Halo Remote, which has a range of 350m in clear line of sight and is available separately. - Red, green, blue, amber, purple, and white colour options - Approximate battery life of 130 hours for red, green, and blue - Approximate battery life of 75 hours for amber, purple, and white - Approximate standby life of 552 hours (23 days) with quality new batteries - On and off control via Halo Remote (range of 350m in clear line of sight, available separately)
