Our miniature and sub-miniature LED lights are the smallest, lightest LED penlights you can buy. The sub-miniature is smaller than a cigarette in length and width. The miniature light is thinner than a cigarette and only 10cm long! Battery life is extraordinary. Brightness is incredible for such a tiny light.

For comparison, check out the size of the lights versus a common pen. These lights are really small!
Using our modified FSC-F717 infrared sensitive camera, we took a picture of the various LED Mini lights. The violet one on the left is a 400nm ultraviolet light. The far two lights on the right are 880nm and 940nm infrared lights. The 880nm and 940nm lights are not visible to the human eye. You need an infrared sensitive camera (such as NightShot camcorders) or night vision equipment to see the light. Notice that cameras cannot simultaneously focus on UV, visible and IR light. This is because the wavelength affects the focal length on the lens. If you focus on IR, the visible light won't be in focus. In this picture, we focused on the visible white light so the UV and IR lights are not quite in focus.
Here you can see our LEDMn400 with the 400nm LED illuminating invisible ink. Note: 400nm will illuminate most UV fluorescent inks; depending on the ink or dye, it might not work as well as the 375nm LED or 365 fluorescent tubes. The 400nm is less expensive than the 375nm LED unit and much smaller. The 400nm is very well suited for automotive leak tracing dyes which are tuned for 400nm lights. 700mcd output with peak at 400nm. This is the same LED that others rate as a 395nm LED, however, though they are looking at the minimum frequency, not the peak.
Note: The lower the wavelength, the more expensive the LED. A UV 400nm LED cost much less than a 375nm UV LED. Because of this, we have found that many flashlights are incorrectly labeled to show a lower wavelength than what they are. Since we have a spectrometer and integration light sphere, we can test the flashlights for actual power and wavelength. With some of our invisible inks such as invisible red and invisible yellow, a 365nm light will work well while a 400nm light will not.
Both the LED Mini and LED Sub-Mini lights use 3 volt Lithium BR435 batteries. The LED Sub-Mini uses one battery while the LED Mini uses two batteries. The BR435 batteries, as you can see from the picture, are rather small. We stock the BR435 batteries at great prices.
