The JetBeam ST Cycler XM-L T6 Reviews & Features

Its looks are likely to be known as the enthusiast JETBeam proven and popular JETBeam III PRO ST body shape was used. That is, this is a whole new light with an XM-L LED T6 and developed a new interface for cycling and outdoor sports.
 

 


What's in the box
Customary accessory package includes an olive green lanyard, two spare O-rings and a tail cap switch boot. JETBeam a registration card with serial number was included as a guide in my review sample.


Initial overview
The light is compact (121mm - 25.4 mm OD) to streamline and fits comfortably in the palm of your hand and creating very little drag once mounted your bike helmet or handlebar. The light body (70 grams) is the typical JETBeam dark gray color with HA III Military grade hard anodized. It has a low profile but effective stabilizer tail design and stand-ability. Both will be valued during your camping trips. The body and tail cap knurling is not overly aggressive, but also helps in giving you a positive grip. The rear clicky switch is easily accessible and the tail cap has lanyard ring slots.

Settings
 

JETBeam has created two completely separate platforms mode activated by tightening or loosening of the head. Within these modes, you have to give separate settings give an overall picture of a total of seven different exposure settings.The first mode level or in the open mode is available on select fully tightening the head then with the rear clicky switch to the desired setting.This level has a memory mode is activated so that each mode can be selected to be kept in memory and when you turn your light on.Within this mode, four different settings are available:The first is with a 425 turbo light output. This is a mountain bike downhill cyclists on fast and technical trail riding, where much light is required to be used.The second setting (high) is a very respectable 190 lumens with a long duration of 3.5 hours. This is supported by many who want a decent performance with a prolonged period and, again, is of MTB'ers, road cyclists and campers, dog walkers, cavers are encouraged etc.The third setting (Medium) is giving you 50 lumens and runs for 14 hours. This is well suited as a marker light also great for cycling.The last setting is the flash that is built very common with all Chinese lights. This, I am sure that the least used of all the different settings, but perhaps could use to scare off an attacker.The second mode level or cycling mode is obtainable by dissolving the head about an eighth of a turn.The first setting is a low 10 lumens. This has an incredible run time of 45 hours and can be used as a marker for cycling light, but I personally think that this is better for a campsite for tasks where not much light is needed.The second is a slow but very powerful flash (425 lumens) is ideal for cyclists in urban areas where it is more important to be seen than to see your front wheel. Due to its high power flash output can be used very effectively in daylight.The third setting is an innovative warning light setting with a powerful 270-lumen with a built-slow pulse combined. This gives you the best of both worlds, that it was built a riding light with a warning device in it. The light pulsation is quite unobtrusive and will not interfere with the normal non-riding night-vision.The above two settings for the general road cycling are designed and security modes can see this in my mini-video clipsThe last setting is an SOS mode. This will hopefully never needed, but it is reassuring to know that in an emergency, you can use your light as an SOS beacon for rescuers to locate you.I think JETBeam not have to give a very good choice by a remembrance made of its secondary mode, and the placement of its low light (10 lumens) as their first easy adjustment.Head in the unlocked position, you are guaranteed a friendly sight have output when the light is turned on. This is particularly important if, for example, that you get up in the middle of the night, because you do not get blinded as fast as you need to turn it on.All settings are easily available by simply clicking the back half pressing the switch when the light is turned on. The other two planes are mode by easily screwing or unscrewing the head.

 More clever stuff
The ST-cycler has a purpose designed new reflector for cycling and other outdoor activities designed to give you a pretty big bright central
Range and good ambient lighting.
This is ideal for mountain bike trail ride, where a combination of both is not required.

Rain will not be a problem because the ST-Cycler is submersible up to two meters and corresponds to the IPX-8 waterproof standard.
The light is also the double-spring system, should cushion the shock and is always a good battery connector fitted. It is rated shock-proof to 1.5m
and has a built-in system on the discharge for 18650 rechargeable Li-ion batteries. This will give you a flashing warning when the battery is nearly flat (for me this is another safety factor, for while we are warning you will be able to change the mode, 10 lumens low, you are more at maturity).
(Note that this system does not work with some of my cheaper batteries, which of course is a battery problem)
The light can also be performed on two CR-123. There is no voltage data in the manual, but I have contacted JETBeam and I am informed that the light lasts up to two rechargeable CR127 ie 9V (8.4V total)

MTB riding with the ST CYCLER
This was tested during a night ride in Friston Forest in Great Britain. The light was powered by a 2400mAh rechargeable battery AW. During night driving, the light was positioned on my handlebars. I used to drive the various settings on forest tracks and was able to secure and happy with the turbo, high and warning lights when driving downhill. The medium setting was me just enough light on the wide track uphill fire. For its relatively small size, the ST-Cycler is a big bright light beam with a very respectable throw in the turbo mode. I was seeing with my old faithful JETBeam III PRO ST BVC, which has a closer and more far-reaching beam, ideal to round corners. The ST-Cycler has been for over an hour on the Turbo setting without appreciable loss of brightness used during this period.
