It’s a good idea to have a flashlight or headlamp with you on vacation as you can use it walking around at night from your car to your room or on the beach, or whatever.
A really good idea is to wear some sturdy shoes and walk around outside your resort grounds at night around 9 pm. You’ll probably find lizards sleeping in the bushes and on tree trunks you’ll find gliding geckos and gliding lizards if you’re lucky. Lizards in the Acanthosaura genus sleep on strong tree trunks, just hanging on, head high, tail low.
The best headlamps in my own opinion, after about 12 yrs of experience in the forest, are the Petzl headlamps. Excellent quality of build and light pattern and color. Not usually cheap, but the little 350 lumens Reactiks are excellent headlamps you can get for the entire family at around $40 each. The light lasts for many – dozens of – hours and it’s super lightweight.
I got so into headlamps that I created a headlamps website. No kidding.
Or, if you’ve forgotten to bring a headlamp, just go to Tesco and get a blue and white 7 inch long (18cm) Toshino “Living Simplicity” flashlight. It is re-chargeable, lightweight, and the damn battery just won’t quit on these things. It’s an LED light with either 3 or 6 LEDs you can turn on at a time. I used one for 5 hours of snake hunting, then, as a test, turned it on 36 hours ago – on full 6 LED – and it is STILL WORKING. It is not as bright as it was with full-charge – but the fact that it’s still working after 41 hours of use is incredible.
I think it cost 160 THB in 2019.
