I took the EF1 out on a mine exploration trip and tested it underground for brightness and function (see the video above)
details and specification of the torch below
The Nitecore EF1 Explosion-Proof LED Torch has a maximum brightness of 830 lumens from the Cree XM-L2 U3 LED & is powered by 1×18650 or 2xRCR123 Li-ion or 2xCR123 batteries.
Constructed from aerospace grade aluminium alloy in its body construction with a thickness of 3mm (20% thicker than regular flashlights). Together with the 10mm thick epoxy reson explosion-suppressive optical lens, EF1 can provide secured illumination in hazardous areas (Zone 1, Zone 2, and Type IIA, IIB, IIC and T1-T5 Level, as GB3836 rated), and indoor / outdoor operations (such as factories, stations, stadiums, railway tunnels, culverts) for electricity, smelting, railway, mine, port and civil construction industries. EF1′s explosion proof class is IIC. It’s Equipment Protection Level is Gb.
The EF1′s sliding switch control enables for rapid & accurate one-handed brightness adjustment through the three brightness settings.

Head diameter of 40mm for choosing filters & diffusers
Large Tan Spotted Beetle – Oncideres Cingulata – Twig Girdler | 1080HD
While I was out in the country in south Texas, I came across a twig girdler (oncideres cingulata). These large brown beetles have been making rings around my mother’s trees, which causes the tops to fall off. This process kills the tree. Since these longhorn borer beetles have been cutting down her trees, she’s poisoned them, but apparently not well enough, since I found this one alive and well. They have a beautiful tan and brown spotted pattern that looks almost like granite or marble. I even let the cat play with it as a video bonus! I flipped it over to show how it returns itself upright. I even let it walk up my pants to show climbing speed. It got a little too close for comfort towards the end!
I did eventually behead the pest beetle, in a bit of karmic justice. Even though I really didn’t want to kill it, I thought it best for the local natural scenery.
It is a brownish-gray beetle typically 1/2 to 5/8 inch in length in the Family Cerambycidae. It is characterized by long antennae, 1/2 to 1 inch long.
This beetle is widely known for the damage it causes to pecan plantations, but also to lumber trees such as hickory, oak, poplar and elm. In late summer and fall, the adult female girdles small branches (1/4 to 1/2 inch diameter) with its mandibles, cutting through the bark and into the wood, resulting in an effect that looks almost as if it were cut with a small saw. The female lays her eggs singularly in a separate cut into the wood, above the girdled section. Shortly after the twig is girdled and inserted with eggs, it will die and fall from the tree to the ground. The white, legless larva overwinters in the twig, then eats its way through woody tissue to the girdled point in the dead twig, and eventually closes itself in the twig with shredded wood fibers, then pupates over 12 to 14 days. The adult emerges and mates in the summer, feeding off tender woody shoots. This concludes the beetle’s single yearly generation.
Twig girdlers create a difficult infestation in plantations, as they occur late in the season close to nut harvesting. Collecting and burning dead twigs during the winter is key to fighting infestations. They can result in significant crop decreases in the following year, and can also result in the structural problems inherent to amateur pruning.
