1521 lumens on 8W, dimmable from 10 to 100%
This GY A60 LED bulb is an E27 retrofit lamp that replaces a 100W incandescent while drawing only 8W. It delivers 1521 lumens at 185 lm/W and is rated Energy Class B, so it addresses the running cost of older bulbs rather than just the purchase price. The 360-degree beam and CRI 80+ output suit living rooms, bedrooms, kitchens and garages, and it is available in 3000K or 4000K and in 6PCS or 60PCS packs.
Why an ordinary bulb falls short
A standard incandescent turns most of its input into heat, and many low-cost LED replacements sit in Class E or F with lower output. This GY bulb is rated Class B at 185 lm/W, so it produces 1521 lumens from 8W. Over 3000 hours the difference is visible on the meter: 24 kWh for this bulb against 54.3 kWh for a Class G LED, with a 29-day payback at the stated usage. It is a direct E27 retrofit, not a new fixture.

- Energy Class B, 185 lm/W
- 24 kWh vs 54.3 kWh over 3000 hours
Brightness and running cost
At 1521 lumens the A60 bulb gives the light level of a 100W incandescent while using 8W. The 185 lm/W figure is what separates it from a typical E or F class LED, which often delivers only around 800-1000 lumens. For a room lit several hours a day, that gap adds up across a year. The bulb runs on 220-240V and is dimmable from 10 to 100% with compatible LED dimmers, so brightness can be lowered without changing the lamp.
- 1521 lm from 8W
- Dimmable 10-100% with compatible LED dimmers
- 220-240V input
Light quality and colour choice
The 360-degree beam spreads light evenly in pendants and chandeliers rather than pooling it downward. CRI 80+ keeps fruit, cake and interior colours closer to daylight than a CRI 60 or 70 source, and the bulb is flicker free, which matters for phone cameras and for long periods under the light. Two colour temperatures are available: 3000K warm white for living rooms and bedrooms, and 4000K neutral white for kitchens and work areas.
- CRI 80+ for natural colours
- Flicker free
- Available in 3000K and 4000K
Fitting and installation
The A60 body measures 97 x 62 x 115 mm and uses a standard E27 screw base, so it fits most pendant lamps, table lamps, chandeliers and open ceiling fittings. Installation is a simple screw-in swap with the power off. Check the dimmer is rated for LED loads before relying on 10-100% dimming, and allow ventilation in enclosed fixtures. The bulb is supplied in 6PCS or 60PCS packs for single rooms or larger installations.

Frequently asked questions
Can it replace a 100W incandescent?
Yes. It produces 1521 lumens, comparable to a 100W incandescent, while drawing 8W from a 220-240V supply.
Is it dimmable?
Yes, from 10 to 100% with compatible LED dimmers. Check that your dimmer is rated for LED loads to avoid flicker.
Will it fit my lamp?
It uses a standard E27 base and an A60 body of 97 x 62 x 115 mm. Check the space inside the fitting before ordering.
Can it be used in enclosed fixtures?
It is best used in fittings with some ventilation. Tightly enclosed fixtures can reduce lifetime and dimmer performance.
How much do several bulbs use?
Each bulb draws 8W. Three bulbs together draw 24W, and six draw 48W, compared with 100W per incandescent replaced.
How long does it last?
The rated lifetime is 30,000 hours, which is long compared with the 1,000 hours of a typical incandescent.
Which colour temperature should I choose?
3000K warm white suits living rooms and bedrooms; 4000K neutral white suits kitchens and work areas. Both are available in this listing.
What pack sizes are available?
The bulb is offered in 6PCS and 60PCS packs, so you can cover a single room or a larger installation.
