A simple plug and play garden laser that will project over 1000 red and green dots over an area up to 40\' x 40\' when the projector is positioned 30\' away. To reduce the coverage simply move the projector closer to the object you are illuminating. These clever lasers feature a useful \'light sensor\' at the top of the lens, so they will operate only when it is dark. (Handy Hint: If you wish to use the laser when it is light, you can simply cover the sensor with a sticker!). There are four settings on the light simply operated by a push button on the back.. 1. Red + Green Light 2. Red + Green Flashing Light 3. Green Light 4. Red Light Red Laser 650nmGreen Laser 532nmClass2 LaserTransformer IP44 220-240VCord Length 2.9 Metres
