15W Spiral Energy-Saving Bulbs

Product Detailed Description

A ceiling fixture with a dim corner, a cabinet that needs brighter light, or a maintenance cart restocking older installations: spiral energy-saving bulbs cover all three without a change of socket. The bent-glass spiral tube fits standard screw bases, so distributors can range the format by shape and base rather than by brand.

Build and light quality

• Working voltage: 220 to 240V
• Power: 15W
• Color temperature: 2,700/6,400K
• Average life: 8,000 hours

Tricolor phosphor and clean tube alignment are the details worth checking side by side in a sample batch, since these vary between factories. The bulb saves 80% energy compared with older incandescent lamps and reaches full brightness quickly in everyday domestic use.

Bases and customization

Capacity: E14/E27/B22 covers the common European and British fittings, letting one bulb family serve ceiling, cabinet and table applications. Branding is mainly a packaging exercise: private-label cartons, printed boxes and shelf-ready retail packaging. The glass shape itself stays standard, which keeps customization simple and costs low.

Retailers that merchandise bulbs by shape find the range easy to plan. Confirm the base and socket types used in the target market before comparing color temperature, and order alongside work lights or table lamps for a fuller lighting assortment.
