I like to travel rough, but nothing is rougher than the overhead fluorescent lighting I find in most $10 a night hotels.
I bought this primarily for video calls with clients, but I use it almost every night as my primary lighting source.
It conveniently folds down to about 6x4” with a depth of 1/4”. It hangs from hooks, or clings to metal with 2 powerful magnets. It can be used folded, flat or inflated, for any number of photographic applications. The color temperature is completely adjustable and it charges with a USB-C cable.
