FROM THE DESK
The power went out in my neighborhood at 11 PM on a Saturday. I stepped outside and realized I couldn't see my mailbox 30 feet away. No streetlights. No porch lights. No ambient glow from anything. After about 10 minutes, my eyes adjusted and I could see shapes, outlines, and the neighbor's white fence. But those first 10 minutes of total darkness were disorienting in a way I hadn't expected in my own front yard.
Here's what I've got this week.
THE BRIEF
Operating in the Dark: Skills for When the Lights Go Out
Most emergencies happen at inconvenient times, and a significant percentage happen at night or in low-light conditions. Earthquakes don't wait for sunrise. Power outages hit at midnight. Evacuations happen in the dark. Your ability to function without light is a practical skill.
Night vision adaptation takes 20 to 30 minutes. Your eyes switch from cone vision (color, detail, bright light) to rod vision (peripheral, movement, low light). Once adapted, you can see far more than you'd expect. The catch: one exposure to bright light (a phone screen, a flashlight in your eyes, headlights) resets the adaptation and you start over. If you need to preserve night vision while using a light, use a red lens. Red light doesn't reset rod adaptation.
Flashlight discipline matters. In a dark neighborhood, a flashlight advertises your position and activity to everyone within line of sight. Use it when needed, but use it deliberately. Point it at the ground in front of you, not straight ahead. Use the lowest setting that lets you navigate safely. Turn it off when stationary.
Navigation in the dark relies on memorized routes and tactile cues. Walk your property in daylight and note landmarks: the garden hose, the fence corner, the crack in the sidewalk. These become navigation aids at night. Inside your home, count steps between rooms. Know where furniture is by touch. Practice moving through your house with your eyes closed.
Low-light tasks require preparation. Your flashlight should be within arm's reach of where you sleep (Issue 46). A headlamp frees your hands for carrying, first aid, or navigation. Red-lens options preserve night vision. Glow sticks provide ambient light for hours without batteries and mark locations or paths.
For driving in dark conditions without streetlights, reduce speed significantly. Your headlights illuminate about 300 feet ahead, which at 60 mph gives you less than 4 seconds of reaction time. At 35 mph, you have nearly 6 seconds. The slower pace also reduces the risk of hitting debris that outages scatter on roads.
ONE THING THIS WEEK
Turn off all the lights in your house and navigate from your bedroom to your emergency supplies.
Do it once. Notice what you bump into, what you can't find, and how long it takes. Then do it with a flashlight. The difference tells you what you need to change.
ON THE RADAR
CDC: Salmonella Outbreak Linked to Moringa Supplements Spreads to 36 States — 119 Sick, Multiple Brands Recalled
The CDC is tracking a multistate Salmonella outbreak tied to moringa leaf dietary supplements, with 119 confirmed cases across 36 states and 32 hospitalizations as of May 27. No deaths have been reported. Multiple brands recalled products: Live it Up Super Greens, Why Not Natural, Mogo Moringa capsules, and TNVitamins moringa capsules. A separate drug-resistant Salmonella strain is also linked to moringa powder from a February 2026 outbreak. If you use moringa-based supplements, check the FDA recall list before your next dose.
LESSON FROM: CLINT EMERSON
Clint Emerson's 100 Deadly Skills includes detailed sections on low-light operations drawn from SEAL experience. His principle is that darkness is not a disadvantage for the prepared person. It's an advantage. Someone who can operate effectively in the dark has a significant edge over someone who can't, whether the context is personal safety, navigation, or emergency response.
Emerson's practical advice: become friends with the dark. Spend time outside at night without a flashlight. Let your eyes adapt. Walk familiar routes. Your comfort level in darkness directly affects your effectiveness in any nighttime emergency. Fear of the dark is primarily fear of the unknown, and that diminishes with exposure.

WHAT'S HAPPENING
US Military Kills 205 in Pacific Drug Boat Strikes — Operation Southern Spear Seizes 200,000+ Pounds of Cocaine
The US military conducted its fourth strike this week under Operation Southern Spear on Saturday, killing 3 in the eastern Pacific and pushing the total to 205 killed since the campaign launched in September 2025. US Southern Command said the targeted vessel was engaged in narco-trafficking operations by a designated terrorist organization. The Trump administration has declared the US in armed conflict with Latin American drug cartels, noting that 74% of US-bound cocaine transits the Pacific. The Coast Guard seized 511,000 pounds of narcotics in 2025 — a service record valued at $3.8 billion — including more than 200,000 pounds of cocaine from the Pacific in the first six months of FY2026. US drug overdose deaths peaked near 110,000 in 2022 and have fallen sharply since: down 27% in 2024, with fentanyl-specific deaths dropping 36.5% from 2023 to 2024 — the longest sustained decline in decades.

WHAT WE’RE TESTING
This headlamp has 450 lumens on high, but the feature I use most is the red light mode. It provides enough light to read, navigate, and work without destroying night vision adaptation. I keep it on my nightstand.
During the midnight outage, I grabbed it, switched to red mode, and could see everything I needed without blinding myself or anyone else. The elastic headband is comfortable enough to wear for hours, and the rechargeable battery lasts 2 to 130 hours depending on mode.
For hands-free operation during any nighttime emergency, a headlamp is superior to a handheld flashlight. Your hands stay available for carrying, climbing, or first aid. About $50.
Budget alternative: Any LED headlamp ($10 to $15) plus a piece of red cellophane taped over the lens. Creates a makeshift red light mode for almost nothing.
Pick up the Petzl Actik Core Headlamp on Amazon — about $50 for the rechargeable version with red light mode.
OVERRATED / UNDERRATED
Overrated: Night vision devices for civilian preparedness. They cost $500 to $5,000, require batteries, and solve a problem that a $50 headlamp and basic night skills handle for 99% of scenarios. Unless you're in a very specific security situation, your money is better spent elsewhere.
Underrated: Glow sticks. A 50-cent glow stick provides 8 to 12 hours of ambient light, marks a path or location, doesn't need batteries, and is visible without being blinding. Keep a handful in every kit.

PS: After the midnight outage test, I moved two pieces of furniture that were in my dark navigation path. The next time I walk that route in the dark, it's a straight line with nothing to hit. Small change. Big difference at 2 AM.
