I found a method how to make the CM Torch shine much brighter.
Theoretically infinite brightness is possible (until your LED dies).
I am not responsible if you damage your LED or your device with this guide. If you point with your finger on me I will laugh on you.
1. Open Torch app
2. Turn Torch on
3. Force kill Torch process - LED remains on
4. Open Torch app again
5. Tap on Torch symbol -> LED increases brightness
Repeat steps 3-5 as often as you want
I tested repeating three times on my Galaxy Ace 2 with CM11, works well.
Power LED off:
Open Torch App and tap as often until it turns off.
Good Luck, aprofomo
