Sunco ST64 Dusk to Dawn vs Sengled A19 Dusk to Dawn: Which Bulb Fits Your Porch

The choice between the Sunco ST64 and the Sengled A19 comes down to one question: does the fixture need a visible vintage filament bulb, or does it need maximum light in a plain envelope? The Sunco is the decorative pick for exposed outdoor fixtures, and the Sengled is the practical pick for porches and garages that just need to come on at dusk. The comparison below sorts the two by look, brightness, coverage and price tier so a buyer can settle it quickly.

Sunco ST64 Dusk to Dawn Outdoor Edison Bulbs vs Sengled A19 Dusk to Dawn Sensor Bulbs

Sunco 4 Pack Dusk to Dawn ST64 Outdoor Edison Bulbs LED

Brightness: 800 lumens
Color Temperature: 2700K soft white
Wattage: 7W, 60W equivalent
Base: E26
Shape: ST19 clear filament (sold as ST64)
Pack Size: 4 bulbs

The Sunco is built around appearance as much as illumination. The clear glass and exposed filament read as a vintage Edison bulb, so it suits lantern-style porch lights, post lamps and open fixtures where the bulb itself is part of the design. The 2700K soft white output keeps that warm, amber-leaning look rather than a clinical white.

At 800 lumens it is roughly a 60W-equivalent replacement, which is enough for a single entryway or a pair of sconces but not for flooding a driveway. The integrated photocell handles the on/off cycle automatically, so no timer or smart switch is needed. Four bulbs per pack also means a multi-fixture setup gets spares in the same box.

Trade-off: The clear filament glass is more delicate than a frosted envelope and the warm 2700K output is dimmer and softer than a daylight sensor bulb, so it is a poor fit for anyone who needs bright, wide coverage.

Sengled Dusk to Dawn Light Bulbs Outdoor, A19 LED Sensor Bulbs 6 Pack

Brightness: 1200 lumens
Color Temperature: 5000K daylight
Wattage: 10.5W, 75W equivalent
Base: E26
Shape: A19
Pack Size: 6 bulbs

The Sengled takes the opposite approach: a standard A19 envelope with no decorative ambition, aimed purely at output and coverage. At 1200 lumens and 5000K daylight it throws a much brighter, whiter light than the Sunco, which suits garages, side entries and porches where the goal is to see clearly rather than to look period-correct.

The A19 shape fits almost any standard E26 fixture, including enclosed or semi-enclosed ones where a long filament bulb would not clear the glass. The built-in photocell switches the bulb on at dusk and off at dawn with no wiring changes. Six bulbs per pack covers a whole house’s worth of exterior fixtures in one purchase.

Trade-off: The plain frosted A19 and cold 5000K daylight output look utilitarian in a decorative lantern, and the high brightness can be harsh in a tight entryway where a softer bulb would read better.

How the Two Dusk to Dawn Bulbs Differ

Light Output and Color

This is the widest gap between them. The Sengled delivers 1200 lumens of 5000K daylight, while the Sunco delivers 800 lumens of 2700K soft white. That is a difference in both quantity and character: the Sengled is bright and neutral, the Sunco is warm and comparatively dim.

For a buyer lighting a garage apron, a back door or a driveway, the Sengled’s extra output is the deciding factor. For a buyer lighting a front porch where the fixture is decorative and the light is meant to feel inviting, the Sunco’s warm tone holds up better. Neither is wrong; they solve different problems.

Shape, Fit and Fixture Compatibility

The Sunco’s ST19 clear filament shape is long and exposed, designed to be seen. It works in open lanterns and post lights but can crowd a small enclosed fixture or a tight sconce. The Sengled’s A19 is the standard bulb shape and clears almost any E26 socket, including semi-enclosed housings.

Buyers with enclosed fixtures should lean toward the Sengled. Buyers with open decorative fixtures should lean toward the Sunco, where the filament is the point.

Pack Size and Value

The Sunco ships as a 4-pack and the Sengled as a 6-pack, and the Sengled sits at a lower price tier despite the larger count. On a per-bulb basis the Sengled is clearly the cheaper option, which matters for anyone replacing every exterior bulb at once.

The Sunco’s premium is for the vintage look, not for output or count. A buyer paying that premium is paying for appearance.

Automatic Operation

Both bulbs use a built-in photocell, so both switch on at dusk and off at dawn without a timer, smart hub or app. There is no meaningful difference here. The decision rests entirely on light quality, shape and price.

Which Should You Buy?

Choose the Sunco ST64 if the fixture is decorative and exposed, the goal is a warm vintage look, and 800 lumens per bulb is enough for the space. It is the right pick for lantern-style porch lights, post lamps and period homes where the bulb is visible.

Choose the Sengled A19 if the priority is brightness, coverage and value. It is the better fit for garages, side entries, driveways and any enclosed fixture, and the 6-pack covers a whole exterior in one order at a budget price tier.

Frequently Asked Questions

1. Do both bulbs turn on automatically at dusk?
   Yes. Both the Sunco ST64 and the Sengled A19 have a built-in photocell that switches the bulb on at dusk and off at dawn, with no timer or smart home setup required.

2. Which bulb is brighter, the Sunco ST64 or the Sengled A19?
   The Sengled A19 is brighter at 1200 lumens versus 800 lumens for the Sunco. The Sengled is also a cooler 5000K daylight, while the Sunco is a warmer 2700K soft white.

3. Will the Sunco ST64 fit in an enclosed fixture?
   The clear filament ST19 shape is long and designed for open, decorative fixtures. It is a better fit for lanterns and post lights than for tight enclosed housings, where the standard A19 Sengled is the safer choice.

4. Which bulb is the better value?
   The Sengled A19 sits at a lower price tier and ships as a 6-pack, making it cheaper per bulb than the 4-pack Sunco. The Sunco’s higher cost buys the vintage filament look rather than more light.

5. Can both bulbs be used outdoors?
   Both are marketed for outdoor lighting and use a standard E26 base. As with any outdoor bulb, the fixture itself should be rated for exterior use and protected from direct water exposure.

6. Do either of these bulbs need a smart hub or app?
   No. Both rely on an integrated photocell for automatic operation, so neither needs a hub, app, Wi-Fi connection or smart switch.

7. Which bulb suits a garage?
   The Sengled A19, because its higher 1200-lumen output and daylight color give better visibility for a garage exterior than the warmer, dimmer Sunco.

Bottom Line

The Sengled A19 Dusk to Dawn is the better all-round buy for most households: brighter, cheaper per bulb, and easier to fit into any E26 fixture. The Sunco ST64 Dusk to Dawn is the pick only when the fixture is decorative and a warm vintage filament look matters more than raw output. Check the current price on Amazon before deciding.
