I'm hoping to buy a new bike soon, and can't decide if I want to spec a Dynamo hub and Dynamo light and charger
Here is my 2p FWIW.
For pbp23 I wanted to ride the new trike. Previous 5x pbp on dynamo, considered new wheel and dynamo ..
I went for 2x Lumintop battery lights. Best value and run time. Low faff. Last Arrive cover shows my setup
The lights are torch type with a shaped beam. replacable 21700 cell. You get 10 hours at 260 lumens from each cell six were more than enough for pbp
I did a lot of night riding. Will cover lel.
Easy to switch the spare lamp on for extra illumination.
Approx cost lights £25+£25, protected 5000mAh cells £14 each total £134. Considerably less than a dynamo.
Lights 85g, cells 70g. Lights USB chargeable. Just
less faff to swap cells. With six I effectively had a 60,000mAh power bank.
I carried all (to start with) on pbp. No need with drop bags on lel.
You should by now realise, dear reader, that just £40 will get one to evaluate.
Deffo recommend If your use scenario is one long ride every couple of years. The spare light/spare cell flexibility covers off the flattery light negatives.
I do though have a good collection of cateye rear primary cell lights that are now unobtanium. Read upthread about having to charge rear lights.

Update on this. After using the Lumintop B01 flashlight a couple of times and on a 600 in june, I decided this would be less hassle then the ebike light + battery pack.
Used it on LEL and it was perfect. Good enough beam on medium mode (supposedly 11 hours) and ability to switch to high easily for faster bits. Worked great on all the big descents in the pennines. Used 3 5000mah cells over the course of LEL (took 5 in total). Also took a spare B01 as they're so light/cheap. The included mount also worked flawlessly.
My riding partner also bought one and his first use of it was on LEL. He was impressed.
In summary, it makes a great audax light. Unlimited battery life based on how many cells you bring and you can even power it with a usb-c powerbank.
