1. Why LED Bulb Assembly is a Growing Business in India

LED bulbs have replaced CFLs and old incandescent bulbs because they are:

Energy efficient (up to 80% savings)

Long-lasting (15,000+ hours)

Affordable due to local manufacturing

Supported by government schemes

In demand in residential, commercial, and industrial segments

Since the components are inexpensive and easy to assemble, small entrepreneurs can enter this industry with very little experience or technical knowledge.

2. Total Investment Required (₹1–5 Lakh Setup)

You can start LED bulb assembly with the following approximate investment:

Component Cost (Approx.)

Basic Assembly Machines ₹40,000–₹1,50,000

Raw Materials (initial stock) ₹30,000–₹1,20,000

Tools & Testing Equipment ₹20,000–₹50,000

Shop/Workspace Deposit ₹10,000–₹30,000

Initial Packaging & Branding ₹10,000–₹40,000

Licenses + Misc Expenses ₹10,000–₹20,000

Total Investment:

👉 Minimum ₹1,00,000

👉 Maximum ₹5,00,000 depending on scale

This makes it one of the most affordable manufacturing businesses in India.

3. Space Required (200–500 Sq Ft)

A small rented shop or room is enough.

Ideal layout:

100 sq ft – Raw material storage

150 sq ft – Assembly and soldering

50–100 sq ft – Testing & QC

50 sq ft – Finished goods & packaging

You do not need an expensive location. Even an industrial area or affordable market lane will work perfectly.

---

4. Staff Requirement (Only 3–4 Workers)

This business requires basic operational staff:

1. Assembler (2 workers):

Assemble housing + LED driver + PCB

2. Testing technician (1 worker):

Uses testing jig, multimeter, aging machine

3. Packing helper (1 worker):

Stick labels, box packaging

If budget is low, you can start with only 2 people and scale later.
