The team over at LumeCube is up to it again! They have a new product they are kicking off and you can be part of it and get it at a great price, but only if you hurry. These are an updated version if the LumeCubes I have been using to shoot GoPro and iPhone video at night. They are extremely bright for such a compact LED. Click the link and see for yourself. Their are many different levels that you can contribute too.
Here’s a link to their KickStarter page: http://www.lumecube.com/154-6.html
