15 Min Cool Down in Fridge Restart
15 Min Cool Down in Fridge Restart EXPOSURE DOWN
Observation:
- S12DD is only brighter than S12Factory in the first 2 minutes (37% brighter).
- After 2 minutes both are about equal.
- At 16 minutes, DD seem twice as bright compared to factory due to extreme thermal regulation on factory S12.
- Restart after 15 minutes cool down in the fridge, S12DD brightness remains the same but Factory S12 is brighter than S12DD now.
Conclusion:
The 37% brightness increase from S12DD for 2 minutes is not worth the mod. IMHO, the best way to increase an S12 performance is deactivating its thermal sensor, thus prolong the 800 lumen threshold. I believe the tiny resistor in photo 2 is related to the thermal sensor. The light works perfectly with both the red and black wires de-soldered from the tiny resistors. I will let it sit for another 15 minutes and report back. If output does not drop then we have just derived an easy method to turn off the thermal sensor.
Send me any questions
