Miniature Lamp 28W S11 6.2V

The Lumapro 3EHL3 is a clear incandescent miniature lamp rated at 27.9 watts and 6.2 volts AC. It uses an S11 bulb shape with a double contact bayonet base (BA15d) and produces 402 lumens of white light at 2300K. The glass envelope measures 2 3/8 inches in overall length. It is designed for indoor use only and carries trade number 1724.

Thermal Noise Power Draw

As an incandescent source, the lamp converts most input power into heat rather than light during normal operation. The glass housing becomes hot to the touch and the unit operates silently with no fan or ballast noise. Power draw remains steady at the rated 27.9 watts when supplied with the correct 6.2 volt AC source. Dimming is not supported by this model.

Sustained Load Behaviour

The rated life is 400 hours of continuous operation before expected filament failure. Light output and colour temperature remain stable throughout the rated lifespan until end of life. The lamp is not shatter-resistant and is not approved for enclosed fixtures where heat buildup could shorten the 400 hour rating. No three-way switching capability is provided.

Questions about this item

How do I install the Lumapro 3EHL3 lamp into a BA15d socket without damaging the contacts?

Align the pins on the double-contact bayonet base with the socket slots, push gently until seated, then twist clockwise to lock; forcing it straight in bends the pins.

When should I replace this 28W S11 lamp based on its rated life?

The rated life is 400 hours; plan replacement once the lamp reaches that point or if light output drops noticeably before then.

What is the first limitation I will hit if I run this 6.2V incandescent lamp continuously in an enclosed fixture?

The lamp is not rated for enclosed fixtures; heat buildup will likely cause early filament failure before the 400-hour rating is reached.
