I’d try a slightly different solution: Why not give them a real torch?
Find the ‘cheapest’ two AAA torch (like about £4 each). What I'm hoping for is the long term: The torch is useful for changing a tyre or during a power cut.
(Edit: With the three AAA designs, the batteries are fitted into an adapter. I've found the adapters to be very fragile. So I'd avoid that style of torch.
I've done a search for the larger AA torches in a small budget, I've added what I found. I suspect/fear the larger batteries would just be drained 'faster' for an even brighter torch...)
1. It should take a small knock… or can be fitted with a wrist lanyard. If the torch is all rubber it could be bulky and it’s extra weight.
1b. Plan B: If you really need padding, look for some hockey tape?
1c. Plan C: It was £4...
2. It’s likely to be single function. With a button on the tail. You have control over this.
3. It will be bright and effective, so they need to learn a little responsibility
*. You might be able to mitigate some performance by using lower voltage rechargeable batteries(?). But this ‘problem’ might be engineered out.
3b. If you want to be a little naughty what about scuffing the lens with a little sand paper??? Or shim the reflector out of alignment. Or add wood glue/craft glue (PVA) to the lens.
4. It will clearly look like a torch and should serve the house for a few years.
*I don’t see much value in buying an inferior torch with sub-standard tech… unless it was critical that the torch needs to be resistant to a two year old. I know this is a bit of a can 'o worms.
My counter-point is that when Maglites blow a bulb, there's a hot piece of glass/metal... broken glass to be changed in the dark. The modern COB units don't have these problems... or step back to discrete LEDs if that better fits your needs. (But the discrete LEDs tends to mean sillyness with battery holders, Exactly what I want to avoid.)
Basic idea:
( This set of two.... dang repeats... are <£4 )

* Obviously this is NOT 5000 lm... more like 150 lm tops... It's a torch made with exactly the same parts.
