Commercial grade solar spotlights complete with sturdy die-cast aluminium ground anchor spikes, but they can also be screwed to a flat surface if preferred. The three solar spotlights come with 2 metres of cable between them allowing them to cover 6M in length, there is also 2 metres of cable from the solar panel to the first light. Each spotlight incorporates a glare shield which prevents excess light pollution and a more intense concentrated beam of light, each spot producing up to 630 lumens, with a beam projection of approximately 5 metres. Unlike a lot of spotlights these are 3000K, which is a warmer white than the usual harsh daylight blue whites, so whilst still being very bright, they also appear soft and welcoming. The solar panel is a high quality polycrystalline 6V 8W model measuring 34cm x 25cm, that will reach a full charge in only 6 hours of good sunshine, which could provide power for up to 3 days. As this set also comes with a remote control you can also choose various timer options of 3,5, or 8 hours on, or just set to constant on or off. They also have an in-built dimming sequence which also helps to make sure these keep shining all night long. Dimming sequence - 1 hour @ 100% brightness, 2 hours @ 70% brightness, 4 hours @ 50% brightness, 5 hours @ 30% brightness (shorter if battery fully discharged) Functions - 3 hours on, 5 hours on, 8 hours on, Adjustable brightness, Constant on/off override Orders delivered outside UK mainland may incur additional delivery charges or around £25 ex vat, please call for pricing first - 0345 505 9090 LEDs 7W LED COB Chips (per spotlight)630 Lumens (per spotlight)Warm White (2700K-3000K)IP67Battery - Lithium ion phosphate (18650) 4AH 3.7V (2 pieces)6V 8W Polycrystalline silicone solar panelCharging time 6 to 10 hoursUp to 3 nights illumination2 metres cable between each spotlight, and from panelWorking temperature -25 to 60˚CMade from die-cast aluminium, and tempered glassGround spike or surface mount
