Our 35 watt controller can be loaded to 24 watt of our LED lamps and our 75 watt with 52 watt. Each lamp has a wattage of LED specified see each lamp specification: example 3 watt or 1 watt etc etc . In addition the number of lamps which can be used is also effected by the distance you wish to run the wiring from the controller. Low voltage dissipates over distances so there is a specified amount of LED watts which can be loaded on each wire subject to distance.
Our product is ideal for most projects and if there are cases where distances beyond 90 meters are involved then its easy just to design in mains power at 2 or more locations around the project.
Go to Planning your installation to learn more. For large projects where the further light is > 90 meters from the controller a practical design is to locate additional mains powerpoint closer to the subject and use more than one controller.
The planning your installation page will help you plan.Each controller has 4 wiring legs you can load and run in different directions around your project.
Simply said: legs running long distances are loaded with less lamps compared to legs running shorter distance which can be loaded with more lamps.
Most commonly customers will load equally the 4 legs unless they have one or more features which are much further away from the controller compared to other features.
If you have overloaded a long distance leg this is not dangerous to you or the product : simply the light intensity / level from the lamp will be less or the light at the end furthest from the controller may not come on.
Assuming you use the specified thickness of wire core as 7.5 mm to 9.5 mm which allows maximum flow of low voltage current you can run wires from each of the 4 legs up to 90 m.
But importantly the LED watt loading on such distance is low at 1 watt.
The optimum is 50 meters from the controller when using all of the 4 legs with equal loading or run 1 or 2 legs furthest distance and the other 2 legs at shorter distance until the maximum loading to distance is achieved Again see the planning your installation page to learn more
Fit the controller to an outside wall in open air either plugged into an outdoor waterproof socket or hard wired into a mains 170-240 volt power source. The controller encompasses a light sensor which allows
lights to be programmed to switch on and off triggered by ambient surround light levelsSo this is the reason to seat the controller in a location where it reads atmospheric light levels and is not as an example placed inside a building or covered area which could lead the sensor to read a dark ambient and switch on the lights.
For 2 reasons a) to allow you to run wiring in different directions and distances around your project allowing all areas to be lit simultaneously and controlled by the single controller an b) To allow your to balance the number of lamps and their wattage loading up to the maximum loading of the controller.
Our LED lamps are designed to minimise the amount of wattage used to create high quality lumen: in other words use the best quality components and you get the best light efficiency per watt of LED LED lamps use on average 90% less electricity compared to conventional 240 volt main halogen lighting so simply said one of our controllers running 10 lamps or say 25 watts of LED 6six hours per day,365 days per year will use about £10 per year in electricity
