Bulb bases vary by fixture: table lamps typically use standard E26 (medium) bases, while smaller accent lamps and some bubble accents use candelabra E12 bases. Listings also mention compatible bulb types such as incandescent, halogen, and LED.
Maximum wattage varies by product: some table lamps list up to 150 watts, many smaller lamps list 60 watts, certain string sets list totals like 35 watts, and nightlights may show very low ratings (for example, 0.05 watts).
Listings show bubble lamps used as bedside or accent lighting in kids' rooms, foyers, and over kitchen islands. Plug-in bubble nightlights and themed bubble-string lights are suggested for hallways, entryways, dresser tops, mantels, windowsills, staircases, and holiday trees.
Controls vary by model: some accent bubble‑glass lamps have built‑in dimmers for full‑range dimming, some table lamps use 3‑way socket switches, and plug‑in nightlights typically use a simple on/off switch.
