Crowdfunding is the in thing these days. Everyone is onto it, even students who are doing school projects are putting their projects onto crowdfunding sites.
But are they really the most valid sources of information? I think not. Take SPOT for example.
From their indiegogo site, this seems like a pretty good deal, 6 AAA batteries can get you 8 hours of battery life on a 10W LED, and it’s a pretty nice looking torchlight. In fact I was almost on the verge of putting down money when I realised the numbers were off. You see, I own a few of these high powered torchlights, and I knew for a fact that they could not last anywhere near the numbers advertised here.
So I did some maths. The largest typical capacity of a AAA battery available to us normal human beings is 1200mah at 1.5V. That translates it to 1800mWh, or 1.8 watt-hour. 6 of these batteries at tip top conditions will give you 10.8 watt-hour. That light there is a 10 watt high output LED. And the sellers are telling us that that is enough to last 8 hours. I repeat again, a high output LED that consumes 10 watts per hour to operate can last 8 hours with only 10.8 watt-hour. Does anyone else see a problem with this?
Now, I’m not accusing them of being dishonest. They might just be ignorant and simply pulled a nice number from nowhere to make their product look more attractive. But misinformation by up to 8 times? I think there’s something wrong here. If they had tested it and put there that their light lasted 1 hour, I might have considered getting it. Now, I’m not even sure that they tested it. Someone really needs to regulate this industry.
