I think you will have better depth of field with white light,
absolutely, Jim
here is what I learned the hard way. From my trail journal
7/28/09 - Up at 4:30 long before the 4:59 alarm has a chance. Ready to go at 5:30, but darkness still reigns. There is no need to brood waiting on the launch pad, so to speak, so I take off. Minutes later I am reluctant to pick my way over a rocky stream-crossing because of limited depth perception with the LED headlamp's lavender light. So I sit, turn the headlamp off and wait. Dawn is already trying, so after just 10 minutes I feel comfortable to move, reaching the junction to Bench Lake an hour later.
