    Default Converting garden lamp post to solar

    I've got a tall (8ft) colonial style lamp post which is current powered by 240V. We leave it on in the evening for visitors; however often leave it on by mistake over night - and don't realise until the morning.

    I'm thinking about adding a solar light to the lamp post (in addition to the 240V globe), so it comes on for a few hours when the sun goes down. I was planning on getting a solar garden type spot-light or similar (something high power) from bunnings, removing the housing and placing the solar panel on top of the lamp post and installing the globe in the lamp. Has anyone tried anything similar and if so any recommendations on suitable lamps/parts. Purchasing the parts separately (solar panel, etc), seems much more expensive and difficult than using the parts from garden lamp or similar.

    I haven't tried it but as long as you can get separate the different parts from whatever lamp they are built into then it shouldn't be too hard.

    Another option would be a sunset switch and timer for 240V operation. That would switch the light on when it gets dark and off at whatever time you set (or sunrise, whichever comes first).

    You may find that the packaged solar light combos will be too dim if you put it in a foreign enclosure (like an old style lamp post). It will be missing the appropriate reflectors around the energy efficient globe.
    What you could try though is to build something yourself that is more powerful. Check out the attached images. You can put a kit like this together for about $100 from Jaycar. But is it really worth it?

    Hi Tricky

    The el cheapo packaged solar lights from the deep discounters can be surprisingly good except for the battery, which is almost always crap. Just replace the rechargeable battery with a good quality one - minor soldering may be necessary.

    Cheers
