Description

The Energizer 1.8W G4 LED capsule bulb replaces traditional 20W halogen bulbs with a low-energy LED alternative that produces 215 lumens at 2700K warm white. The G4 bi-pin base fits standard G4 lampholders found in under-cabinet lighting, display cases, desk lamps, and decorative fittings where halogen capsule bulbs were previously used.

Designed for accent lighting, decorative fixtures and task lighting in kitchens, living rooms and bedrooms, the bulb draws just 1.8W on 12V DC supply and delivers consistent output without the heat buildup associated with halogen equivalents. The non-dimmable design means the bulb switches on to full brightness immediately and maintains stable output throughout its rated 15-year lifespan based on average household use patterns.

The compact capsule form measures approximately 10mm diameter and 35mm length, fitting inside small lampshades and enclosed fixtures where space is limited. The 300-degree beam angle provides wide light distribution rather than a focused spot, making it suitable for general illumination in multi-bulb fittings. The warm 2700K colour temperature produces a soft yellowish-white light comparable to traditional incandescent and halogen sources.

Frequently Asked

What voltage does this G4 bulb require?

G4 capsule bulbs typically operate on 12V DC supply via a transformer or driver. Confirm your existing fitting uses 12V before installation — mains voltage G4 fittings are rare but do exist and require different bulbs.

Can this bulb be used in enclosed fittings?

Yes. LED capsule bulbs run significantly cooler than halogen equivalents, making them safe for use in enclosed decorative fittings, under-cabinet housings and small lampshades where halogen bulbs previously caused heat issues.

What does the 15-year lifespan mean?

The 15-year rating assumes average household use of approximately 3 hours per day. In commercial settings or fittings left on for extended periods, the actual lifespan in calendar years will be shorter, though total operating hours remain the same.

How does 215 lumens compare to the halogen bulb it replaces?

A 20W halogen G4 capsule typically produces around 200-250 lumens depending on manufacturer, so the 215-lumen output of this 1.8W LED provides comparable brightness at one-tenth of the power consumption.
