Flashlight tool or enchantment

I have seen an idea mentioning the topic, but didn't go into detail, although my idea is that the telescope could be either crafted into a flashlight like a carrot/warped fungus on a stick where once crafted can't go back until it runs out of durability, or there could be an enchantment on it (this is the side I saw the other person go with) that allows the telescope to be used as a flashlight but my addition to the topic is it must be charged with glowstone and if you were to try looking through it you will get blindness depending on how long you looked through it
