Flicker in LED Floor Lamps: Reading the Driver Before the Wattage
LED sources respond to current almost instantaneously, which means any ripple left by the driver appears directly as light modulation. Whether that modulation is visible depends on its depth and frequency, and both are properties of the driver output stage rather than of the LED board itself.
For residential floor lamps the practical consequences are two. Under a phone camera a modulated source produces banding across the frame, which customers read as a defect even when the light looks steady to the eye. In reading and task positions, sustained modulation is a comfort complaint that tends to appear in reviews rather than in returns.
A driver specification worth requesting states the output ripple at rated load, the dimming method and the usable dimming range. Dimming is where flicker usually appears: a driver that is stable at full output can begin to modulate at the low end of a phase-cut or pulse-width dimming curve.
A quick bench check does not require laboratory equipment. Pointing a phone camera at the lamp through its dimming range and watching for moving bands catches the worst cases, and comparing two samples side by side on the same dimmer is more informative than reading the numbers separately.
For buyers building a private-label range, the useful step is to fix the driver requirement in the specification rather than to approve a finished sample. The LED board, the diffuser and the mechanical parts can change between orders; the ripple behaviour follows whichever driver is fitted, so it should be named.

Frequently asked questions
Which personal-care appliances are best for private label?
Blackhead removers, facial cleansing brushes, hair stylers and massagers are popular, low-complexity SKUs ideal for first-time private-label launches.
How do I source small home appliances from a China manufacturer?
Work with a factory that shows certifications, a real production line and references. Aolemon handles tooling, QC and global shipping from Hangzhou, China.
What certifications do personal-care appliances need for the EU/US?
The EU requires CE + RoHS (and often REACH); the US needs FCC and, for connected devices, the relevant electrical-safety marks. We supply the paperwork per destination.
