Lumintop BLF GT Giga thrower 2000+ lumen 2.5km LED search light
1800g, 2000 lumens, 1,290,000cd: This light outputs over 2000 lumens from a Cree XHP-35 High Intensity in Neutral White 4000k with a reflector that is huge to collect the light and propagate over 2000m of throw. Some people have claimed to hit over 3000m from real world tests with this light, that's how impressive it is. It will make you giggle on how impressive it is in size and throw illumination capability. Available in Cool White and Neutral White tints!
By default the GT firmware is set to suit most users and applications, but several settings are user-configurable. To enter the configuration settings, press& hold the button for about 8 s (3 s if in the MODE-SET UI), do not release until a double flash followed by a single blink is seen. The single blink is the prompt for the first setting. Click the button as many times as required for that setting, or leave the setting alone and simply wait for the next double flash, this time followed by two blinks, indicating that we are now at setting #2, etc.
The GT confirms each click with a blink. A press& hold skips to the next setting. A continuous press exits the setup menu completely. Four blinks indicate that the setup is completed.
The available settings differ, depending if the GT is currently set to the R ING UI or the MODE-SET UI. Note that changing setting 1 flips to the other UI and immediately kicks you into the table for that UI:
12 V Cree XHP35 High Intensity, neutral white, mounted on copper DTP MCPCB
Tom E’s open-source NarsilM v1.2
 By default the GT is set to use the very intuitive Narsil smooth R ING UI. Instant access to a 2.5 A TURBO mode is also provided.
 A more conventional discrete level MODE-SET UI is available as an alternative. Any one of 12 pre- defined mode-sets can be selected.
 MOMENTARY mode is useful for signaling purposes or rapidly/briefly lighting up targets.
