💡 DIY Guide: Making a Local 150W LED Bulb at Home



If you're into electronics and want to build a high-power 150W LED bulb, this guide is for you! It’s great for use in workshops, shops, farms, or outdoor areas where you need bright and energy-efficient lighting — at a low cost.



🧰 Materials You’ll Need

ComponentDescription / Notes
150W LED plateAluminum base preferred (for cooling)
LED driver (150W)Match voltage & current to LED plate
Heat sink or metal baseFor cooling the high-power LED
Thermal pasteImproves heat transfer
AC wire with plugFor power input
Heat-resistant glueFor fixing parts
Optional: DiffuserTo cover the light, reduce glare

🛠 Tools Required

  • Screwdriver

  • Soldering iron + solder

  • Multimeter

  • Wire cutter & stripper

  • Safety gloves

⚠️ Safety Tips

  • Always test with care — 220V AC is dangerous

  • Work in a dry, non-metallic area

  • Wear rubber slippers and gloves

🔧 Step-by-Step Guide

✅ Step 1: Mount the LED Plate

  • Apply thermal paste to the back of the 150W LED plate

  • Fix it onto an aluminum heat sink or metal body

  • Tighten with screws or glue for strong bonding

✅ Step 2: Connect the Driver

  • Check the output voltage of the driver (typically 48V–80V DC)

  • Connect driver output wires to the LED plate terminals

    Red = + Positive, Black = – Negative

  • Use solder or proper screw terminals

✅ Step 3: Connect AC Input

  • Wire the AC input (220V) to the driver’s input terminals

    Live (L) and Neutral (N) — double-check marking

  • Attach a power plug if you want it portable

✅ Step 4: Test the Bulb

  • Plug into 220V AC carefully

  • The LED should turn on with bright light

  • If not, check connections or test driver output with a multimeter

✅ Step 5: Add Casing (Optional)

  • You can use a plastic or aluminum bulb casing

  • Fix the diffuser if you want a soft light effect

  • Ventilation holes are recommended for heat

🔍 Power Calculation (Just for Info)

  • 150W at 220V = approx. 0.68 Amp

  • Monthly consumption if used 6 hrs/day =
    150W × 6 hrs × 30 days = 27 units

🛒 Where to Buy in Pakistan?

  • Hall Road Lahore, Saddar Karachi, Abbott Road

  • Online: Daraz, Homeshopping, Symbios, Robu.pk

  • Ask for: 150W LED Plate + Driver + Heat Sink

🧠 Final Thoughts

Making your own 150W local LED bulb is a cost-saving, high-brightness solution for shops, halls, or outdoor areas. With a little effort and care, you can also sell custom LED bulbs in the local market and grow your own small business.
