Product guide

Gresonic 500-LED Fairy Lights, 10 m, Warm White

Warm White: Gresonic 500-LED fairy lights are a mains-powered string for indoor or outdoor decoration, with adjustable colour temperature, dimming, timer settings and remote control. The listing gives the light string an IP44 rating but says the transformer is not waterproof, so outdoor use requires a protected receptacle for the transformer.

At a glance

The manufacturer describes nine lighting modes, four brightness levels and timer choices operated by remote or plug buttons.
The feature description claims ten adjustable colour temperatures from 2000K to 3800K, while the details table lists 2000 Kelvin.
The string is described as IP44, but the transformer is not waterproof and needs a waterproof receptacle cover outdoors.
The listed 10 m length is the light string. The feature description adds a 5 m power lead, giving 15 m total cable length.

What to know before buying

Listing details to confirm

The listing contains inconsistent or unconfirmed details: the title says 2000–3800K and nine modes, the details table lists only 2000 Kelvin, and the mode description names Comb, several colour temperatures and effects without clearly matching nine modes; it also lists USB as a wireless connection despite describing corded mains power and remote control, and gives both waterproof and IP44 claims. Treat these as listing discrepancies rather than settled specifications. The transformer is explicitly not waterproof, so keep it protected from water outdoors.
