Bat Signal Spotlight Lamp – E14 & MH001 Compatible

🇬🇧 FULL DESCRIPTION (ENGLISH)

Bat Signal Spotlight Lamp

Bat Signal Spotlight Lamp is a 3D-printed spotlight-style lamp inspired by the iconic Bat-Signal, designed as a functional and decorative desk or display light.

The lamp features a cylindrical spotlight housing with side pivots, allowing smooth rotation, mounted on a structural support frame and a round base. Inside the spotlight, a conical inner reflector is included and designed to be lined with adhesive aluminum foil to efficiently reflect and direct the light forward.

Light Source

This lamp is designed to use a standard E14 screw bulb.
Small LED bulbs, such as E14 refrigerator bulbs (around 300 lumens), work especially well for this design.

The lamp can also be used with E14 LED bulbs without the plastic diffuser dome. The diffuser can be carefully removed, leaving the LEDs exposed inside the spotlight housing without affecting functionality, as the reflector and housing provide proper containment.

Socket & Stencil Template

A standard E14 lamp socket is mounted inside the spotlight housing.

Since many E14 sockets do not include a retaining ring or pre-drilled mounting holes, this design includes a stencil template to assist with accurate marking and drilling.

• Socket fixing: 2 or 4 × M3 screws
• Hole layout: cross pattern
• Hole spacing: 37 mm between opposite holes (center-to-center)

The stencil ensures correct alignment and compatibility with a wide range of E14 socket models.

Cable Management

The lamp includes an integrated cable routing and strain relief system:

• The power cable enters through the round base
• It passes into the structural frame through a widened internal channel
• This space allows tying a strain-relief knot, preventing the cable from being pulled out or damaged during use

A bottom cap is included to close and protect the cable exit underneath the base.

Assembly & Hardware

Required hardware:

• 6 × M2 screws (≈10 mm length)
  To attach the front bezel to the spotlight housing
• 4 × M2 screws (≈10 mm length)
  To attach the pivot brackets to the support frame
  (slightly shorter screws can also be used)
• 4 × M2 screws (≈10 mm length)
  To attach the support frame to the round base
• 2–4 × M3 screws
  To fix the E14 lamp socket inside the housing

Material & Usage Notes

This lamp has been successfully printed and tested in PLA, which works well for normal decorative use.

Please note:

• This lamp is not intended to remain powered on for many hours continuously
• With prolonged use, heat from the LED bulb may cause slight deformation near the front lens area when printed in PLA
• Using higher temperature-resistant materials (such as PETG, ABS, or ASA) can reduce or eliminate this effect

The model is designed primarily as a decorative and occasional-use lamp, not as a permanent lighting fixture.

Print profiles with properly oriented build plates are provided, along with individual STL files, to ensure reliable printing and easy assembly.

MH001 LED Lamp Kit Compatibility

This model now includes an optional version compatible with the MH001 LED Lamp Kit by Bambu Lab.

Two modified parts are included to replace the standard bulb housing components, allowing direct installation of the MH001 LED module.

Available versions:

• E14 bulb version
• MH
• 001 LED Kit version

This makes the model fully compatible with both traditional E14 bulbs and the official Bambu LED kit.

Bat Signal Spotlight Lamp

Bat Signal Spotlight Lamp is a 3D printed spotlight-style lamp, inspired by the iconic Bat-Signal, designed as a functional and decorative light for desk or display

The lamp features a cylindrical body with side pivots, allowing the spotlight to rotate, mounted on a support structure and a round base. Inside the spotlight, a conical reflector is included, designed to be covered with adhesive aluminum to efficiently reflect and direct light forward

Light Source

The lamp is designed to use a standard E14 screw bulb
E14 refrigerator LED bulbs, around 300 lumens, work especially well

It can also be used with E14 LED bulbs without the plastic diffuser dome. This dome can be carefully removed, leaving the LEDs exposed inside the spotlight, without affecting operation, as the reflector and the spotlight body contain them correctly

Lamp Holder and Stencil Template

A standard E14 lamp holder is used, fixed inside the spotlight body

Since many E14 lamp holders do not include a retaining ring or pre-drilled mounting holes, the design incorporates a stencil template to facilitate accurate marking and drilling

• Lamp holder fixing: 2 or 4 M3 screws
• Hole arrangement: cross pattern
• Separation: 37 mm between opposite holes (center-to-center measurement)

The stencil ensures correct alignment and compatibility with different E14 lamp holder models

Cable Management

The design includes an integrated cable routing and strain relief system:

• The cable enters through the round base
• It is introduced into the structure through a wider internal channel
• This space allows for a safety knot, preventing the cable from coming out or being damaged by pulling

A bottom cap is included to close and protect the cable exit at the bottom of the base

Assembly and Hardware

Required hardware:

• 6 × M2 screws (≈10 mm long)
  To fix the front bezel to the spotlight body
• 4 × M2 screws (≈10 mm long)
  To fix the pivot supports to the structure
  (they can be slightly shorter)
• 4 × M2 screws (≈10 mm long)
  To fix the structure to the base
• 2–4 × M3 screws
  To fix the E14 lamp holder inside the spotlight

Material and Usage Notes

This lamp has been successfully printed and tested in PLA, which works well for normal decorative use

Please note:

• It is not intended to remain continuously lit for hours
• With prolonged use, the heat from the LED bulb may cause slight deformation in the front glass area if printed in PLA
• The use of more temperature-resistant materials (such as PETG, ABS, or ASA) can reduce or eliminate this effect

The model is designed primarily as a decorative lamp for occasional use, not as permanent lighting

Print profiles with correctly oriented parts are included, as well as individual STL files, to facilitate reliable printing and simple assembly
