What this bulb is

The Sunlite 40940-SU is an A19 LED filament lamp that produces a blue hue while drawing only 4.5 watts. It carries a 60W equivalent rating and a medium base that fits most standard fixtures. The dimmable design makes it suitable for residential or commercial accent lighting.

What the dimming and base change

Dimmable operation lets users lower the blue output for subtle mood lighting or raise it for vivid party effects. The medium screw base installs directly into existing sockets without adapters. The transparent coloured envelope keeps the colour consistent throughout the dimming range.

Capacity and headroom

A 15,000-hour rated life means the lamp can replace up to 12 coloured incandescent bulbs over its service period. The low 4.5-watt draw keeps energy costs minimal during extended event use. Buyers who need white light or higher lumen output should choose a different lamp.

Questions about this item

How often will the 4.5 W blue LED filament need replacing?

The lamp life is rated at 15 000 hours, which can replace up to 12 coloured incandescent bulbs over the same period.

What limits continuous operation of this 60 W equivalent blue bulb?

The 4.5 W LED filament runs far below the heat output of a 60 W incandescent, so thermal throttling is not a practical limit in normal fixtures.

How much heat and noise does the dimmable A19 produce when left on all day?

At 4.5 W the bulb generates minimal heat, operates silently and stays cool enough for extended daily use in standard sockets.
