Some manufacturers make coloured filters for their flashlights if you want a more durable option. I picked up a 40mm red filter to use on my Nitecore EA41 which works really well. It has a rubber housing which slips over the end of the flashlight, creating a pretty neat seal. It wasn't all that expensive and it fits perfectly. I use it on the lowest brightness setting.
I already had the flashlight so buying a removable filter made more sense than having a separate red led flashlight for me. Certainly something to think about as the flashlight can be used for multiple tasks (with or without the filter) where a red led flashlight is limited in that regard.
