A simple plug & play garden laser that will project over 1000 red & 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 650nm Green Laser 532nm Class 2 Laser Transformer IP44 220-240 V Cord Length 2.9 Metres
