Hi Folks,
I recently received a sample of a product that I had ordered (a custom item) from China. The product was a display case with LED lighting. The company produces Acrylic items and didn't have much in the way of LED products. Here's a picture of the underneath of the top of the case with the LED's:
1) The output of the light - when I placed batteries in the case the light was very intense, almost blinding. After a period of about 2 hours the light had faded signifyingly. After 4 hours it was very dim, and after about 5 and a half hours dimmer again. Reading on previous forum posts I think the issue is to do with a driver to control the output? The batteries had overheated and if you look closely you can see the battery wrapper was peeling off.
2) Battery life - I'm trying to work out what the battery life should be if the output of the LED's were regulated. I don't have any experience in this but was trying to google how to work out. My calculations thus far:
Batteries of 2.5 Ah
12 Volt LED strip
So to get the Amp Hours:
30 (Watt Hours) = 2.5 (Amp Hour of battery) x 12 Volts (LED strip)
So then to get the hours the batteries to last is dividing the watt hours by the battery power:
30 (Watt hours) / 9.6w/m strip = 3.125
Is that correct? Do I need to multiply the time above by 8 for the 8 batteries.
Any help would be greatly appreciated. Thanks.
