SKU: DEVJ-LOGLED-116
Stock Status:
10 pcs
Delivery Status: 30-60 days
Manufactured on-demand
Description
116 uses a single 16-bit flicker-free board that provides 2/3 of the total logarithmic brightness range of 311. Only in its dimmest levels, increasing or decreasing the brightness results in visible steps between the adjacent brightness states.
All our LogLED drivers are interchangeable with each other as they have the same outer dimensions.
Key Features
- Miniature, easy-to-swap LED elements with active cooling and economical pricing - available in different colors
- Very bright | Fast switching (some tens of microseconds)
- Easy control from a PC/SBC/MC over PapaLink (I2C) | Support up to 127 devices
- Multipurpose BNC connectors to interface with other common lab gear
- Safe 12 V DC operation
- Open-source | User modifiable firmware for custom programs
Suggested Applications
- Light patterns
- Illumination for cameras and microscopes
- Photobiology, photochemistry and photophysics
- Optogenetic stimulation
Safety information
General electrical safety principles apply. Pay attention especially on the following factors
- Never directly view the R30 LED near the max-power. Especially the IR and UV may appear dim to the eye but can cause serious harm or blindness.
- Prolonged +10 s use near the max-power may overheat the R30 emitter leading to its failure or making it too hot to touch. Do not leave the device unattended when near the max-power.
- Caution on extreme ambient conditions: At high temperatures above 35°C the device's cooling capacity is lowered and prolonged max-power use may overheat internal components. High humidity over 90% may causes condensation causing several issues such as corrosion and short-circuiting.
