LED Light Bulbs FAQs

How bright are LiquidLEDs bulbs?

LED brightness is measured in lumens, not watts. Here's a quick conversion guide:

2-3W LED ≈ 25W incandescent (200-300 lumens)
4-5W LED ≈ 40W incandescent (400-500 lumens)
6-8W LED ≈ 60W incandescent (650-800 lumens)
7.5-10W LED ≈ 75-100W incandescent (900-1200 lumens)
11-12W LED ≈ 100-125W incandescent (1300-1500 lumens)

All LiquidLEDs product pages list wattage and lumen output so you can choose the perfect brightness for your needs.

What is the lifespan of LiquidLEDs bulbs?

LiquidLEDs bulbs are designed for over 25,000 hours of use. If you use your light for an average of 3 hours per day, your LED bulb could last over 22 years. This exceptional longevity significantly reduces the frequency of replacements compared to traditional incandescent bulbs, which typically last only 1,000-2,000 hours. Note that all LED bulbs' light output gradually decreases over time, a phenomenon known as lumen depreciation.

Are LiquidLEDs bulbs dimmable?

Yes, most LiquidLEDs bulbs are dimmable, allowing you to create the perfect ambiance for any occasion. Look for the "dimmable" specification on the product page. For optimal performance, we recommend using LED-compatible dimmers. Some older dimmer switches may cause flickering or buzzing with LED bulbs. If you experience any issues, please contact our customer support team for assistance.

What is colour temperature and which should I choose?

Colour temperature refers to the warmth or coolness of light, measured in Kelvins (K):

Ultra & Extra Warm (2000K-2200K): This colour range is warm and closer to a room lit by candles. It’s a very calm type of light, but it may make tasks like reading harder.
This calming light gives off a warm glow, similar to candlelight. However, because it is such a soft light, it may not be suitable for activities that require focus, such as reading.
Warm White (2700K-3000K): This colour creates a cozy, inviting atmosphere similar to traditional incandescent bulbs. It is ideal for living rooms, bedrooms, and dining areas.
Natural White (3500K-4000K): Provides a balanced, neutral light perfect for kitchens, offices, and workspaces.
Cool White (5000K-6500K): This colour delivers a crisp, energising light similar to daylight. It is best for task lighting, garages, and areas requiring detailed visibility.

Choose based on the mood you want to create and the purpose of the space.

Could see the led inside

I love the matte white glass, but unfortunately the element /led part is sort of floppy inside and touches the side of the glass so it’s very bright line where it touches.

Hi Louise,
Thank you for sharing this feedback. Can you please email photos or video to help@liquidleds.com.au of the light bulbs in your fitting showing the issue?

4W Long Tube Matte LED Bulb (E27)

Hello Katherine,
Thanks for leaving us a 5-star feedback. Look forward to your next visit. Have a great day!

Long tube led bulb

The globes look good plus they arrived in appropriate time. Will look good in the antique light when we have had the light fixed. The only issue i have is that 2 of the 3 lights rattle as if something is loose inside. I just wonder how long they will work for.

Thank you for sharing, Ross. We are thrilled that your experience was seamless and that you're enjoying your antique light. The rattling inside the bulb is the thin wires that are folding the LED filament in the correct position. If you check the long clear tubular bulb you will see the wires supporting the yellow filament. Have a great day!
