    different type of helmet light

    A friend has asked me to do him a light for on his site safety helmet




    he gets free AA batteries non rechargeables

    I have a Q5 led kicking around and a 4 AA holder

    he would like it to last a shift and be bright enough to work with no other lights
    He is a maintainance fitter on heavy plant.

    get that dude on a rechargable system and get his work to pay for it. think about the impact of 4 to 8 AAs per shift in the landfill. This is a true opportunity to be green as opposed to buying carbon credits for a RollsRoyce, or whatever......

    Not as fly as scar's

    But here's my little travelling spot. It uses 3 AAA's, but you can get the same covered battery holder with a switch from radio shack (I am not sure what the UK equivalent is, Troutie). It runs off the DX 800mA driver. Achesalot style housing. It velcros to my helmet and provides a great spot.

    A cheap and easy way is to fit a P60 dropin to the helmet with glass lens glued in place in front of the reflector. You can use a AMC7135 driver and a bare dropin is only $2,50. The reflector assembly is usually enough to cool the led.
    Bad thing: you need to put the switch somewhere.. probably on the batterypack.



    Ugly helmet, haha.
    One more thing. When using a headlamp at work you usually want a very wide beam to light things close to you. Most dropins are very narrow.

    Drilling holes in a safety helmet is a no-no. Plan on using a band or velcro for attachment.

    Who has said anything about drilling holes? The holes and rope in my old helmet are original and for attachment of the inner fitting of the helmet... but yes, velcro is good.
