- Best seller of the emergency lights we looked at, with 846 sold and a 4.9 rating
- Switches on in under 0.1 second, fast enough that you barely notice the cut

- Lead acid battery, so expect to replace it after a few years
The Greenfield LED automatic emergency light is our Best Value pick: around ₱1,100 for a twin-head automatic light that runs roughly 16 hours on a single lamp. It’s dim, and for most brownouts that’s a fair trade.
How long does it really run?
Its 6V 5Ah battery drives 2x2W lamps, and listings quote around 16 hours on one lamp. That figure is consistent with the battery’s capacity, so we’re comfortable with it.
Here’s where we’ll be blunt about the paperwork. Published runtimes for this model conflict between sellers, and at least one lists a longer time with both lamps on than with one. That’s physically impossible: more lamps drain the battery faster, always. Plan around the single-lamp number, and assume running both roughly halves it. If a listing quotes you 32 hours on two lamps, that’s a copy-paste error, not a feature.
Is it bright enough?
No, not if you want a bright room. 2x2W is the dimmest of the four lights we compared, roughly a seventh of the wattage of the 2x15W Akari. What it gives you is enough light to walk safely, find your phone, feed a baby, and get everyone to bed.
The two swivel heads help more than the spec sheet suggests. Aiming one down a hallway and one into the room spreads thin light usefully, instead of pooling it all in one spot.
Does it switch on fast?
Under 0.1 second, per Greenfield’s specs, which is quick enough that the room barely registers going dark. It charges in 20-24 hours and is rated to work between -10°C and 40°C, comfortably beyond anything a Philippine house will see.
The battery is lead acid, so plan on replacing it after a few years. That’s normal for this price and type, not a defect.
Is it sulit?
Around ₱1,100 as of July 30, 2026. Check the latest price on Shopee. This is the value pick of the category: you get automatic switching, twin swivel heads, and all-night single-lamp runtime for well under half the price of our Best Overall.
The market seems to agree. At 846 sold with a 4.9 rating it’s the most popular emergency light in this group, and it comes from a brand Filipino hardware stores actually stock.
Who should buy it
Buy this if you want brownout insurance rather than bright light, and you’d rather spend ₱1,100 than ₱2,800. It’s the right choice for a second unit in a bedroom, or a first emergency light for a small home. See how it compares in our best emergency lights in the Philippines roundup, or browse more on our Home Improvement page. Our emergency light buying guide covers how to match runtime to your outages.
Alternatives to consider
If your outages run long and you want the endurance done properly, the Omni AEL-9032L is our Best Overall at around ₱2,800, with a 12V 9Ah battery, published figures that agree with each other, and 8 hours on both lamps. Want the cheapest name-brand option instead? The Akari AELG-L411 is around ₱999, with a smaller battery and 6 hours on one lamp.

Frequently Asked Questions
How long does the Greenfield emergency light last?
Listings quote around 16 hours on a single lamp from its 6V 5Ah battery, which matches the arithmetic. The published two-lamp figure is inconsistent across sellers, and some list a longer time for two lamps than one, which is impossible. Plan around the single-lamp number and treat two lamps as roughly half.
Is it bright enough for a whole room?
At 2x2W, it's the dimmest twin-head we compared. It's enough to move around safely, find things, and get through an evening. For actually lighting a sala brightly, look at a 2x15W unit instead.
How fast does it switch on?
Under 0.1 second, per Greenfield's specs. In practice the room barely goes dark before the lamps come up.
Is Greenfield a real brand in the Philippines?
Yes. Greenfield is a Philippine tools and electrical brand distributed by Herco, with a warehouse in Marilao, Bulacan and wide hardware-store presence. It's also the best seller of the emergency lights we looked at, with 846 units sold and a 4.9 rating.
Is Greenfield a legit electrical brand?
Greenfield is an established Philippine electrical brand, and this ships from Herco Official Store, a recognised local distributor. For anything that stays plugged in permanently, buying from a known electrical supplier rather than a generic reseller is worth doing.
