Running 9-12 3W LEDs With 12V 110Ah or 2x 12V 15Ah Batteries for 8hr Moth Trap?

Hi, I am a novice at electrical wiring and I am building my first project.  I am trying to build a portable moth trap that I’d like to run for around 8hrs. I plan to have between 9 and 12 3W LED bulbs with LED drivers mounted on a heat sink and powered by a 12V battery (12V 110Ah). I have attached a diagram of my project.
I plan to use the following materials:
• LED Power Supplies 9-56Vin 2-52Vout 600mA LED Driver x4
• 9 to 12 3 W LEDs
• Heat sink
• 12V Battery (110 Ah).I’d be grateful if anyone has any comments on the design, feasibility etc. 
Also, I’d prefer to use smaller 12V batteries in series.
Do you think I could use say Mobility Scooter Wheelchair Batteries 2x 12v 15ah as a power supply?
Thanks,Jo

With a single 12V battery, that leaves you with maybe 8V of drive allowing for a flat battery and the LED driver compliance, I assume that you are using some sort of constant current driver.So at this point more details on the type of controller,  the forward voltage drop of the LEDs at the operating current, and the maximum power dissipation allowed on the controller when the battery voltage is 14V would be needed before the answer can be refined.You are showing 3 LEDs in your diagram, from the rough figures, that is  OK, since I expect your forward voltage will be less than three. What is the luminous output from the LEDs at the operating current you have chosen and what light wavelengths are moths most sensitive to?Assuming the full 600mA per string, you have 2.4A total, so for 8 hours you need 20Ah.If you put the batteries in series you can run 6 LEDs in each string, so you halve the number of LED controllers for the same luminous intensity, but it is a bigger hassle keeping the batteries charged.I have assumed the whole system is linear, there are options to modulate the LEDs, which may have some benefits

Just a quick addition to Richards.From my experience most Moths and night flying insects are attracted to a UV light source, which is why the commercial electronic fly killers have a UV lamp as the attractant. With day time insects such as bees the light stimulus is usually a sodium lamp wavelength.
You can add an extra scent stimulus to the trap by adding molasses or pear drops (Amyl Acetate).

Your timing on asking these questions is perfect, because it just so happens that I had an LED floodlight in my front yard that failed and I had to replace the driver in it a few days ago.  I was skeptical of the Chinese LED drivers on eBay, so I bought four different types of drivers from four sellers.   Each driver claimed to be able to drive one to three 3-watt LED's in series and could be powered from a 12-36 volt AC or DC source. All of the drivers were supposed to be constant current. Non of the drivers even came close to meeting their specifications. A couple of them would drive one LED at about 2.5 watts. When I added a second LED the output current dropped significantly. When I tried three LEDS, two of them would not work at all on 12 volts DC, one delivered 400 milliwats, and one delivered 600 milliwatts (total for three LEDs).  ....So the moral of the story is- Do some bench testing and find out what your driver and LED combination will really do. Don't be surprised of they don't match the spec sheet. Once you determine how much current the drivers will be drawing, you can search online for  a battery life calculator.   -Rick
