Security Lighting

Have just received a number of GJD Mini opal PIR's and in each box is a bag containing 4 plastic items. No where in the instructions does it refer to these parts as far as I can see. They do seem to fit in the hole in the back of the sensor where the tamper switch is. There are 3 similar part each with a different length. They may be to waterproof the device but it's not obvious. The fourth piece I've no idea where it's meant to go.

1. How can I choose between the vast number of Floodlights available, across an extraordinary price range ? My preferences are speed of ignition, lower brightness, lower energy, smaller size, weatherproofness, longer life and allows connection to two PIRs. Any choice suggestions ? 2. How can I wire this Floodlight to two PIRs (one inside, one outside my front door) to ensure it lights before I tackle the front steps from either direction.

Dear Sir or Madam I want advice and information on products that you might have that would suit my needs. I want to automatically switch on my driveway lights when, after dark, a pedestrian or vehicle comes into the gateway or starts up the driveway upon leaving the house, so I will need two sensors. I would like to use break-beam technology rather than PIR so that I can have the beam approximately 75 to 100 centimetres off the ground where it will not be triggered by dogs etc. I expect that when the beam is broken a signal will be sent to switching circuitry inside the house which will turn on the lights. The lights should stay on for about 5 minutes before turning off a…
