1) Are there now two models of Light?
Yes. There is the standard version, which is mains-powered and must always be plugged in, and there is the brand-new battery-powered version.
2) What’s the difference?
Both units will run fine on mains power, and both come with power supplies. The battery-powered version has additional circuitry to handle the charging of 4 AA batteries, and which also provides power via those batteries when the mains power is unplugged. This means you can unplug the battery-powered version, and it will operate normally for a few hours (how long depends on how much illumination the Light provides).
3) I backed you for $99 for a regular Light. Do I still get a regular Light?
Yes. If you’ve backed us for a regular Light, that’s what you’ll receive.
4) I backed you for a regular Light but now I want a battery-powered Light! What do I do?
If you have already backed us for $99, all you need to do is to add $30 to your contribution. You can do this by going to our Kickstarter page, and clicking on the big blue button that says “Manage Your Pledge”, then add $30 to the pledge amount. That’s all you need to do.
5) Do I need to change the reward I’m asking for?
If you want to make things perfectly clear, you can change your reward from LIGHT to LIGHT POWER. But we’ll should be able to figure it out, even if you don’t do this. If you’ve pledged $129, we will know that you want a battery-powered Light.
6) I don’t want a battery-powered Light. Do I need to do anything?
No. We’ll know from your contribution level that you want a mains-powered Light.
7) I want a mix of battery-powered and mains-powered Lights. What do I do?
Make a pledge, then send us a message indicating how your pledge to be allocated. We’ll do the rest.
8) The battery-powered Light is really cool, but why are you making us pay extra for it? Why aren’t you just rolling that into the existing reward?
The circuitry for battery power is subtle and surprisingly expensive. In order to provide stable, reliable power both from mains and from the battery - and to charge the battery from mains power - requires a fair bit of circuitry with a few expensive components. The cost of these components (plus development costs) is reflected in the higher cost of the battery-powered unit.
9) Will the battery-powered Light ship at the same time as the mains-powered Light?
Yes, we expect that will be the case.
10) Will it be possible to upgrade a mains-powered Light into a battery-powered Light after the Kickstarter campaign?
We believe so, but we aren’t yet 100% sure of the upgrade path, so you’re taking a small risk that a mains-powered Light will not be upgradeable. We don’t want that to happen, but in the interests of openness and honesty, we need to acknowledge this might be the case.
