Consider a headband=style light (I like Petzl). Gives you bright light wherever you look and works great for reading, sewing, crafting or reading in bed. If use often, consider a rechargeable version.
I don’t know but it is much brighter than anything else I have found. It has three settings for brightness. I use it all the time on the second setting since it is so bright. Check it out on eBay. Don’t pay any more than $12.00.
