content: Not too long ago Dave had a DIY setup for a ring light that he got on one of his mailbag episodes. It took me a little while but I found where to get it from and I was hoping that someone might know of a cheaper kit that might be out there.Here is a link to the kit that I found:http://be.eurocircuits.com/basic/Offtheshelf/product.aspx?ad=18293&ano=kit%20led%20tester-pwm%20dimmer%20and%20ringlight&an=kit-led-tester-pwm-dimmer-ringlightIt's not too bad but with shipping and all to the US it gets pricey. right now I can't even purchase it though as there is a problem with the code on their site and it moves the damn video over the pricing and add to basket buttons....anyway, if anyone knows of another kit that I might be able to get a hold of for a nice price let me know. I would design my own but if someone already has a kit out there it would make life a bit easier and cheaper.

I wouldn't mind getting the other kit but it's kind of pointless without all the components. I don't have a surplus of parts to put it together.Quote from: notsob on February 06, 2013, 04:26:35 amwhat do you mean by "work out what ID you need and ebay one"? That phrase is not clear to me at all.

content: ID = Inside Diameter, you will notice in Dave's video that it did not fit over his camera lens, the ID (i.e. hole) was too small and you can get led ring lamps on ebay for as low as $US40

content: Quote from: notsob on February 06, 2013, 05:26:10 amnow it makes sense. ID is not a common acronym so yeah, I didn't know what you were talking about at first.As for the ebay ring lights the common problem with those is that they are not good for constant light and also are under powered in a lot of cases or just don't have any kind of specs that I can find details on. I looked at the specs of the LEDs in the kit one and they are pretty good and considerably better than the ones I've actually found specs on and they are typically pretty low. I'm looking for something that's decent quality without having to pay stupid shipping from Europe to US, not exactly a cheap thing there.Hell, I can't even check shipping on that eurocircuit site lately as they have some kind of weird error in their site coding that as soon as I put it to US money it moves the damn video above the pricing area. That's quite perturbing to say the least.... I tried in several different browsers and it happens in them all.Also for the inner diameter I was able to read that part and it is actually fine for use with my macro lens so I'm good to go. My lens uses a 58mm filter and the outer diameter of the lens is not that much more from that. Canon 100mm macro.
