how to power 9 10 watt leds from a automotive battery?

I am building a under water array using 9pcs  10 watt green leds, and will be powering from a automotive battery. the led data is. 10 watt green 900 lumens voltage dc 9-10.8  current 900mA integrated approach 3 and 3 My current build has them in parallel due to not wanting to lose all leds if one fails but will change this if its not possible. I am having issues finding  a step up dc to dc adjustable driver that will allow a output of 10.8 volts an a current of 8100mA . Anyone have ideals or a better solution. Thanks.

Does Xbee work under water? Answered

Does anyone know of the range of Series 1, 1mW Xbee modules under water or if that even works? If not would a 60mW one work? And we are assuming that the Xbee does not get wet or anything like that and is in full working condition.

Hello everyone. I recently purchased a new home, of which has some nice Under cabinet lighting. But they are extremely hot when I use them. Heat = wasted energy right? I want to be as Green as possible in my new home.

Each housing has 2 of these bulbs, and I have 4 of the housings. I can't read schematics, but any info would rock. Thanks everyone.

Operating a transformer at half the voltage? Answered

What could be the effects of the output when operating a transformer at half its rated voltage, specifically to the amperage? as two examples: If I had a transformer rated for an input of 240v and an output of 20A at 24v and I was to supply the primary with 120v, what would happen to the output? If I had a variac (autotransformer, variable transformer, ect.) and it was rated for an input of 240v with an output of 0-260v at 11A, what would happen to the output ratings at only 120v?

Coniferous trees (pines, etc) acidify soil under em. Lawn doesn't cope wit this too well. Dump your old boxes of baking soda from freezer/fridge under pine tree. It works. Grass grows better.
