Getting to watch a sea turtle lay her eggs is one of the most incredible wildlife experiences you can have. But seeing this phenomenon requires plenty of planning and preparation! Most likely your turtle experience involves a guide taking you out on the beach, and they may have mentioned that you should bring a red flashlight or red-light headlamp that is turtle safe. But, not all lights are created equal, which begs the question: What’s the best turtle safe flashlight?
As a sea turtle biologist who has spent many nights searching for nesting sea turtles on pitch-black beaches, I can confirm that having a reliable red-light headlamp is crucial for ensuring you get the most out of the experience.
Before we get in to everything you need to know when choosing a turtle safe red-light headlamp, why do you need to use red light around sea turtles? Well, sea turtles are highly sensitive to white light at night. White light can impair their vision and cause them to become disoriented on their return to the ocean, and it can even deter them from nesting altogether. On the other hand, red lights emit a narrow portion of the visible light spectrum, and research has shown that they are much less likely to disturb, deter, or disorient sea turtles. So, red-light-capable lights should always be used when participating in nighttime sea turtle research or a sea turtle tour, as they will allow you to see but will not interfere with the turtles’ natural behaviors.
Features to Consider in a Turtle Safe Flashlight
There are a few key features to consider when choosing the best flashlight for watching sea turtles. To begin, headlamps are generally recommended over handheld flashlights because they allow you to keep your hands free, making it easier to record data or help take measurements of the turtles, as is possible on some sea turtle volunteer programs. Even if you are not participating in research, having your hands free can help you keep your balance and stay safe while walking in the dark, which is never a bad thing! So, in our recommendations we are focusing specifically on turtle safe headlamps.
When choosing a red-light headlamp, there are several factors to consider. These include:
- Battery Life: A long-lasting battery is crucial, especially if you’ll be out on the beach searching for sea turtles throughout the night. There’s nothing worse than being on a beach at midnight and the batteries dying on you! Having a headlamp with a battery life of 8 hours or more is ideal.
- Durability: Sea turtles often nest in tropical places known for unexpected rainfall, which, in addition to the fact that the salt air and sand are hard on electronics, means that you’ll need a durable, waterproof headlamp that can withstand the elements.
- Comfort: Depending on what kind of sea turtle experience you’ll be having, you might be wearing your headlamp for long periods, so it’s essential to choose one that is lightweight and comfortable.
- Intensity: You’ll want the red light in your headlamp to be strong enough to sufficiently illuminate your surroundings without being so bright as to risk disturbing the turtles.
