L8TE Pack

The L8te Black Pack gives you everything you need to take full control of your light environment — from your first morning screen to the moment your head hits the pillow.

Most people don't realize that sleep quality starts with what you do 14 hours before bed. The Black Pack pairs our daytime Yellow Lens with our maximum-protection Red Lens so your circadian rhythm stays on track, no matter what your day looks like.

What's in the pack

• L8te Pro Yellow Lens — for daytime screen use and office lighting (filters 65–75% blue light)
• L8te Pro Red Lens — for 1–2 hours before sleep (blocks 95–100% blue + green light)
• 2× hard protective cases
  

The 24-hour sleep protocol

1. Morning–afternoon: Yellow lens while working at screens — reduce cumulative circadian disruption
2. 2 hours before bed: Switch to red lens — trigger natural melatonin surge and prepare your body for deep sleep
3. Result: Fall asleep faster, gain more deep sleep, wake up fully recovered

The science behind the pack

• Unprotected phone use at night suppresses melatonin by up to 85%
• Even afternoon blue light can delay your sleep onset by 1–3 hours
• Users with full-day protection report improved HRV, faster sleep onset, and better morning cortisol response within 2 weeks
