Gallery: BOTTLED SUNSHINE: Tobias Wong’s Sun Jars


Ever wish you could bottle sunshine? With Tobias Wong’s charming new lighting concept you can. Sun Jars collect solar energy during the day and emit a warm amber glow at night.

    My wife bought me 4 of these for our 16th anniversary. They worked great for 2 nights then 2 of the 4 stopped working. I took them apart and the problem is the battery holders in the units are just to flimsy. The 2 that are still working came from the factory with zip ties holding the battery case together (PRETTY CHEAP). The 2 that are not working do not have a zip tie and the cases have fallen apart. The battery and spring have caused the ends of the case to break off. One of the units that has a zip tie the zip tie has cracked, so in not to long I bet it will fall apart. Is this a common problem? Seems that a product can only be green if it last, If it falls apart after just a couple of days then it just adds to the problem. We will be sending them back.

    […] This homemade sun jar project at Instructables completely charmed me, it’s a DIY version of another version designed by Tobias Wong. The project involves using the components of a garden light which uses a solar panel to charge its battery. The battery in turn powers an LED which switches on when it grows dark. The guts of the garden light are seated in a frosted jar. Leave your sun jar in a window and it will glow for you every night. […]

    I just saw this sunjar on the internet and came here to read other people`s comments about it!
    What i would say is this;
    For those of you (or us i should say) who care about life and the world, we ought to use our intellect to help a project like this take off and really put our creative faculties going and come up with new ideas how this sunjar can really work excellently in deed!
    After all, everyone knows how to criticize practiclaly everything! So why not join up forces collectively and utilize our individual intelligences to take this idea and grow it into somehting that could really work! Everyone would benefit in the end!!

    Anyway, that`s just my way of thinking. Now to conclude i just want to say that this was enough for me to get me going and create a sunjar for my self and test the results and see what else could be done!

    Thanks for reading!!

    If you want a brighter light you could always change the LED with a higher one and put in a recharble batt. but thats just me

    Why not. I think this is a very good idea for a home project, a school project. I’m going to build one.

    you could just get a bunch of mason jars, frost the insides, then get those cheap solar patiolights, rip ’em apart & assemble them into the mason jars.
    this way, it’ll last longer, be brighter, and you’ll get 4 (or more!) for the price of one!

    It does look beautiful and looks like something that can work, perhaps with some correction.

    Hooray for consumerism! It sounds like it has a pretty short wow factor and will just end up in either the junk box or being junked.

    Save up for a real solar panel.

    I purchased a Sun Jar last week, and received it with much excitement. Not only is it solar powered the design looks pretty smart too.

    All I can say is I was disappointed, The quality of the LED’s are awful, The Sun Jar offers no light and will only work in complete darkness, The only way I can get my Sun Jar to give off that warm amber glow is to sit in a room with no other light source, I also tried my Sun Jar outdoors and it even struggled then, replacing the rechargeable battery with a normal one did help, but this does defeat the object.

    Anyway it’s now gathering dust in my living room, and although the LED’s are a disappointment the thing still looks great as ornament.
