1 purchase this year. I needed a headlamp, because zebras don't suit me - in the cold they think the battery is low and reduce the brightness to almost a minimum. I went to a hardware store and looked at lanterns ranging from 1.4 to 10.5 dollars. Progress is unstoppable, cheap flashlights have finally appeared that can be turned on/off at the wave of a hand using a sensor, they have started installing 3535 diodes instead of Seoul SSC P4 clones or something like that. I mean these guys named 1W, 3W and 5W
In the end, I chose a flashlight for $5.7. What's good here - IP54. The back cover has a groove with a silicone round gasket; when it is closed, a counter protrusion presses the gasket on top. It looks something like this
The same is done in Pelican suitcases. But due to casting inaccuracies and inconsistent gasket thickness, there will most likely be a leak in some place when immersed
The button is part of a cast housing and works like a plastic spring; there will be no leaks here. Most likely, if you keep it in the sun, over time the plastic will become brittle and it will come off and there will be a hole at the top. From inside she presses the tact switch
The front glass is made of thick plastic, on the inside there is a wide silicone gasket into which the reflector rests
The diode is very similar to Osram Oslon by wire location, but on Osram's website there is no phosphor coating like CREE. I can't identify it, perhaps some unique Chinese development. The shade has a CRI of about 80, but pleasant, about 4000K
The reflector is clearly suitable for larger and taller diodes, since this diode sits deeper than the lower section of the reflector and only the outer part of the reflector is used. However, the beam has excellent light distribution. Very similar in shape to the beam of Ledil Boom, which is used in Prometheus Alpha. Maybe a little bit already hotspot. He seems to have the same hue shift problem as XP-G3, due to it there are small blue and yellow concentric stripes
Everything inside is on self-tapping screws with a + head. It can be disassembled and assembled easily and reliably. Here's all the filling
This is controlled by CX3860B. Modes 3 - 100%, 30%, off. In 30% mode there is a noticeable PWM, but it is no more than Malkoff with 3 mode MDC heads. There is no mode memory, 100% turns on first, to turn it off you need to go through 30% mode
In 100% mode, the brightness immediately begins to drop and the graph repeats the battery discharge graph. At 30% mode, the brightness stayed on the same line. But I didn't draw a graph for more than 30 minutes because I'm lazy. Most likely it is still constant due to the low current + PWM; as the batteries discharge, it should also drop. The current was not measured. Claimed operating time is 12 hours on alkaline 3*AAA in 30% mode
The flashlight has a personal number, production date and 3 years warranty
The tilt adjustment has 4 positions, between which there are ~15 degrees, a total of 45 degrees. The fixation is quite rigid if you don't jump or run
There are recesses in the front so you can see on a flat surface whether it's on or not
It goes very well with the screwdriver my friend gave me for New Years
I decided to end the warranty and installed Luminus SST-20 with a shaved dome
Hotspot has become narrower, but this is nothing compared to the improvement of CRI. White remains white, and the feathers are the same brown and green as in the light of the sun, which I cannot see now
For working at arm's length this is quite a pleasant beam
I still have 2 diodes from the same batch. When I order Spy 005, I will put exactly this LED there
Today I'll go and buy a couple more of these lanterns for my friends plumbers, I think they'll like it. And also install a 219B 5000K with a dome there
