How Satic EMI-Free LED Bulbs Work
Standard LED bulbs create a hidden problem: they generate high-frequency electromagnetic interference (EMI) on your home’s electrical wiring. This “dirty electricity” radiates throughout your home from every fixture and can be measured with an EMI meter.
Satic EMI-Free LED Bulbs are engineered with ultra-low total harmonic distortion (THD), dramatically reducing the electromagnetic pollution that standard LEDs produce. You get energy-efficient lighting without contaminating your electrical system.
| Specification | Detail |
|---|---|
| Wattage | 9W (equivalent to 75W incandescent) |
| Brightness | 800 lumens |
| Color temperature | 4000K cool white |
| Color rendering | CRI > 80 |
| Features | Quick start, flicker-free, ultra-low THD |
| Quantity | 12 bulbs per pack |
| Base | Standard E26 |
Each pack includes 12 bulbs—enough to replace lighting throughout multiple rooms. The 4000K color temperature provides bright, neutral light suitable for all-day use in kitchens, offices, and living spaces.
Your purchase includes free enrollment in the Dirty Electricity Master Class ($49 value), helping you understand and address EMI throughout your home.
The Satic EMI-Free LED Light Bulbs (12 pk) are shipped directly from Satic in the USA.
How Ocushield Blue Light Blocking Bulb Works
Blue light from artificial sources suppresses melatonin production—the hormone that signals your body it’s time for sleep. Most LED bulbs emit significant blue light, which can disrupt your circadian rhythm when used in the evening.
The Ocushield Blue Light Blocking Bulb filters out 100% of harmful blue light between 400-470nm, producing warm amber light similar to candlelight or a sunset. This allows you to use overhead lighting in the evening without suppressing melatonin.
| Specification | Detail |
|---|---|
| Wattage | 9W (equivalent to 60W incandescent) |
| Brightness | 800 lumens |
| Color temperature | 2000K warm amber |
| Blue light blocking | Up to 100% (400-470nm) |
| Features | Flicker-free, low EMF |
| Energy rating | A+ efficient |
| Base options | E26 (US) or E27 (UK/Rest-of-World) |
Developed by qualified optometrists in the UK, the bulb is FDA registered and designed for general-purpose use at home or in the office. The warm amber glow creates a relaxing atmosphere while supporting healthy sleep patterns.
The Ocushield Blue Light Blocking Light Bulb is available in US and UK socket variants, shipped from the USA or UK depending on your location.
Head-to-Head Comparison
What Problem They Solve
Satic addresses dirty electricity from LED lighting. Modern LED bulbs generate high-frequency EMF on your wiring, which radiates throughout your home. This electromagnetic pollution is separate from light quality—it’s an electrical issue.
Ocushield addresses blue light exposure and circadian disruption. Blue light tricks your brain into thinking it’s daytime, suppressing melatonin and making it harder to fall asleep. This is a light spectrum issue affecting your hormones.
Light Quality
Satic produces 4000K cool white light—bright, neutral illumination suitable for productivity and general use. This color temperature includes blue wavelengths, making it appropriate for daytime but potentially disruptive in the evening.
Ocushield produces 2000K warm amber light—similar to candlelight or sunset. This color temperature contains zero blue light, making it ideal for evening use but potentially too warm for task lighting during the day.
Coverage and Cost
Satic’s 12-bulb pack at $164 provides whole-home coverage at $13.67 per bulb. You can replace overhead fixtures throughout multiple rooms, making clean EMI-free lighting your default.
Ocushield at $35 per bulb is a higher per-unit investment. Most users install these in bedrooms, bathrooms, and evening living spaces rather than throughout the entire home.
When to Use Each
Satic bulbs work all day. The dirty electricity problem exists whenever your lights are on—morning, noon, and night. These bulbs provide clean power conversion continuously.
Ocushield bulbs matter most in the evening. Using them 2-3 hours before bed helps maintain natural melatonin production. During daytime, blue light exposure is actually beneficial for alertness.
Best For: EMF Reduction and Clean Electrical Environment
If you want to reduce electromagnetic pollution from your home lighting, Satic EMI-Free LED Bulbs eliminate the dirty electricity that standard LEDs create.
Satic bulbs work well if:
- You’ve measured dirty electricity in your home and want to reduce it
- You’re working to minimize total EMF exposure in your environment
- You want consistent lighting throughout the day
- You prefer whole-home coverage with a single purchase
- You use LED lighting for extended hours daily
The 12-bulb pack provides enough coverage for your most-used rooms, making clean EMI-free lighting automatic rather than requiring you to think about it.
Best For: Sleep Quality and Circadian Health
If your primary concern is sleep quality and maintaining healthy circadian rhythms, Ocushield Blue Light Blocking Bulbs give you control over blue light exposure.
Ocushield bulbs work well if:
- You have trouble falling asleep or experience poor sleep quality
- You use overhead lighting in the evening before bed
- You experience eye strain or headaches from artificial lighting
- You want warmer, more relaxing ambiance in the evening
- You’re optimizing your bedroom environment for sleep
The warm amber light creates an atmosphere that signals to your body that it’s approaching bedtime, supporting natural melatonin production.
Best For: Comprehensive Healthy Lighting
Blue light and dirty electricity are separate issues—addressing one doesn’t solve the other. Many health-conscious households use both products strategically:
- Satic for daytime lighting: Clean EMI-free illumination in kitchens, offices, and living areas during productive hours
- Ocushield for evening lighting: Zero blue light in bedrooms and bathrooms for the 2-3 hours before sleep
- Satic for whole-home baseline: Replace all standard LEDs to eliminate dirty electricity everywhere
- Ocushield for sleep-critical areas: Bedroom, bathroom, and evening reading areas
This combination addresses both electromagnetic pollution (dirty electricity) and circadian disruption (blue light) for a comprehensive approach to healthy lighting.
What They Don’t Do
Each product solves a specific problem and has limitations.
Satic EMI-Free LED Bulbs do not: – Filter blue light (they produce 4000K cool white light) – Help with evening circadian disruption – Provide adjustable color temperature – Create a warm, relaxing ambiance
Ocushield Blue Light Blocking Bulbs do not: – Eliminate dirty electricity (though they are marketed as “low EMF”) – Provide bright white light suitable for all tasks – Come in bulk packs for whole-home conversion – Work well for daytime productivity lighting
Understanding these limitations helps you identify whether you need one product, the other, or both.
Frequently Asked Questions
Yes, Satic bulbs are 4000K cool white, which includes blue wavelengths. They're designed to eliminate dirty electricity, not filter blue light. If you want both benefits, use Satic bulbs for daytime and Ocushield bulbs in the evening.
The Ocushield bulb is marketed as "low EMF" and flicker-free, but it's not specifically engineered for ultra-low THD like Satic bulbs. Its primary design goal is blue light elimination. If dirty electricity is your main concern, Satic is the more targeted solution.
You can, but the 2000K warm amber light may feel too dim and warm for productivity tasks. Blue light exposure during the day is actually beneficial—it promotes alertness and helps regulate your circadian rhythm. Ocushield bulbs are optimized for evening use.
You can measure dirty electricity with an EMI meter like the Satic EMI Line Monitor. Standard LED and CFL bulbs are common sources. If your readings are high, Satic bulbs can reduce the pollution from your lighting fixtures.
This depends on your specific health concerns. If you have sleep issues, blue light reduction may provide more noticeable benefits. If you're sensitive to EMF or have measured high dirty electricity levels, Satic bulbs address that directly. Many people benefit from addressing both.
Yes, and this is often the most thorough approach. Use Satic bulbs in overhead fixtures for clean ambient lighting during the day. Switch to Ocushield in the evening in rooms where you spend time before bed. This addresses both electrical pollution and circadian disruption.
Satic bulbs use the E26 base, which is the standard US socket. Ocushield offers both E26 (US) and E27 (UK/international) options—select the appropriate variant for your location when ordering.
