Ideal Energy/Battery Source for a Battery Powered Lamppost

Hello everyone,First time posting, so, thank you ahead of time for all your help!Project:I was tasked with creating an outdoor lamppost for an event at a campground (IE: no immediate electricity source). At first, it seemed quite simple, but, looking at the necessary requirements, it seems to be more complex than I thought. Requirements:I need to find a way to power a high-powered LED light bulb (ideally 12W equivalent) for 10 hours a day (for 3-4 nights - for a total of 30-40 hours) without immediate access to an electrical outlet. So, it would be around 20 watt hours a day. This battery source needs to be able to be outdoors, and face rain/weather. There may be a tarp, tent to cover it. I may have access to a generator to recharge my battery source at another location if need be.I currently have a bright DC 12V light bulb that would be ideal for this project, but, I could also use a AC light bulb if need be.Potential Solutions: Connected 6V Lantern Batteries: Connecting multiple lantern batteries together, and swapping them out on a daily basis. Walmart has a set of Rayovac Heavy-Duty Lantern Batteries for around $2.50 each. Pro: Connecting these batteries in parallel and series would give me the 20 ah, and 12v specs needed. \ It would come out to around $15 a day. Would be easy to put in a large water-proof container and connect to the lamppostCons: Bit wasteful - I'd burn through around 20 of these batteries, and would have to recycle/dispose of them Sealed? - Unsure if I could put them in a waterproof container. Do they need venting? Mid-range cost: Would come out to around $50-60 due to the number of batteries needed12V Deep-Cycle 20Ah+ Battery: A simple 20ah+ deep-cycle battery would provide me the DC power needed on a daily basis. I would then detach it during the day, and bring it to the generator to charge. Pro: Cost - Relatively cheap, at around $50, this battery option would be affordable Set it and Forget It - No need to connect multiple batteries together. This would just be an easy wiring job.Con: Venting - Unsure if I could place this in a simple waterproof container outside. Does it need to vent? Or, would a AGM deep-cycle battery be ok in a vent-free container? Recharging - Unlike the lantern batteries, I would need to bring this to a generator on a daily basis to recharge. Not the end of the world though.Ideas:I am vacillating between both options. Ideally I would like to go with the deep-cycle battery, but I am quite concerned with the venting problem. I don't believe the 6V batteries need to vent, so they could be placed in a simple container.Question(s): Does one of these solutions stand out more to you as the better fit? Are there other battery solutions that you think would work better? Do I need to use a deep-cycle battery, or would something like this battery work?Again, thank you ahead of time for any guidance you could provide!

Is it possible to modify a Bluetooth Receiver to use inline microphone of stereo earbuds instead of unit built in mic?

For years I have been using Bluetooth Receivers such as this Sony : https://www.amazon.com/gp/aw/d/B0154G9CYY?psc=1&ref=yo_pop_mb_pd_title# The problem is they all have built in mic which I don't like, I prefer to use the online mic on my wired earbuds headset. So question is if I were to disassemble the bt receiver device and disconnect the built-in mic would it then let me use the inline mic on my on my earbud headset?

Dual timer switch

Is there a commercial dual timer switch that the first timer can be set for longer duration like hourly or half hourly and then switch on another timer that run in seconds. Or is there a DIY solution? Eg. Turning on a water sprayer every 2 hours for 10 seconds. I need a timer that run from the mains.

How does competition voting work?

I want to enter a competition but it's only 3 days till the deadline. How does voting work? Do people who post their entry early on have an advantage since more people get a chance to vote on the instructable? Do I even bother writing the instructable?
