It's not really a problem. Many, many, different companies, and different models from each company are run this way every day. The total life of the battery is reduced a little but not much and consumers just live with it.
One has to be careful not to leave the light unattended and have it run down too far, that will kill the battery too. Some lights don't have any circuitry to protect from this problem either.
Plus some of the lights need 14 hours to recharge so you need to know what time you are getting up to go to work and start it early enough. If you need to leave the house at 6:00 am you may need to start charging at 4:00 pm for a full charge. What if you get home at 6:00 for example? Some charge fast enough so this is not a problem.
The lights vary, what will work for one light may not work for another. Some types of batteries last longer if you don't run them way down often. One just has to read the instructions for the individual light.
