    Take the "L" away from lamp lol

    dont know if this helps but hitecsecurity.de/pro…171


    Infra Red LED lamp enables IR sensitive traditional style cameras to see up to 30 metres in complete darkness. Side Bracket for attaching unit to a Housing and Bracket, DC socket for 12V DC 750mA. 2 Year Guarantee (1 Year on LEDs)

    doesnt 750ma stand for Milli amp?

    do you know the resistance because then you can work out the current through the light and from that you can work out the fuse required

    You can't put too much of a amperage through the unit, you set the voltage, the amperage needed is then taken, up to the limit of the power supply. I.e. a mains supply can be up to 13 amp, it doesn't mean your lamps at 0.25 amp blow up, does it?

    ok thanks people no idea with amps ma etc

    Also, reading your post again......you don't push current into a lamp, the lamp draws current from the supply, so you need a 12V supply that can supply 12 Volts and over 1.2Amps.

    Going from the product's information, I would suggest 12v and 1 amp would be more than sufficient.

    You thought which? 500 mA is too small, 750 mA may or may not be enough, but since the item is stated as being 750 mA, I would avoid the possibility of having an undersized power supply.

    so what do i go with or where could i find out? as its going to be on 24hr aday

    As I say, 1 amp should be right.

    If I was in your position then I would buy something like a 12V DC 5AMP supply from fleabay, you can also buy similar from maplin. The reason I would choose a supply that is rated higher than the 1Amp required is because it will be working well within its design limit and should not run hot during prolonged use, this should also mean that it will have a longer life. This is not rated for outdoor use.

    but 5amp maybe to much? if so pop and £100+ down the drain.
    as with amp i dont understand that much i though as long as it 12vdc it would work?
    with it being 30metre infra red light, if say i put 3.5amp in and it to low? would the light still look 30metre? or would it only do part of the job?
    thanks

    The supply needs to be rated at 12V and be capable of supplying enough current to meet the needs of the lamp.
    If you have a supply rated at 5A, then you can safely connect a lamp that draws 1A or a lamp that draws 2A or a lamp that draws 0.5A. You cannot connect a lamp that wants to draw 6A as this could cause failure.
    A 5A supply is safe for your need.

    Electrical work should really be carried out by a qualified person.

    With all due respects you do not seem to have the basic grasp of electrical circuits.

    I would suggest getting someone qualified to do this.

    Is it going to be sited outdoors and how are you supplying it?

    This story is worrying me a little.
