A little more expensive than a PT-04 set but it has more utility, especially in a cave. Good for light painting.
Mea culpa, didn't notice you were in Israel, pretty sure there are no Lowe's home improvement stores there. But a flashlight is still a good idea for light painting. LED, something advertised as "tactical".
Thanks for the prompt replies. I've tried "painting" with a LED flashlight and the photos has a distinct green tinge (which can be corrected quite well in Lightroom). The LED flashlights I've tried don't give a balanced white (around 5000K-5500K). If any company were to develop a powerful LED flashlight with a CRI index of 90 or better, I'd be one of their first customers.
