## SECTION 7: B2B BUYER GUIDE SUMMARY

For the complete guide, see: https://hub.ledtubelightfactory.com/en/t8-led-tube-manufacturer-guide

**How to Choose T8 LED Tubes (5-Step Process):**

Step 1 — Identify your installation type: Check if your existing ballasts are electronic or
magnetic. Electronic ballasts → consider Type A (ballast-compatible). Magnetic ballasts or
new installations → Type B (direct-wire) is recommended.

Step 2 — Select the right CCT: Office/retail → 4000K (neutral white). Warehouse/industrial
→ 5000K (cool white). Hospitality/residential → 2700K–3000K (warm white).

Step 3 — Verify certifications: North America → UL or ETL + DLC QPL (for utility rebates).
Europe → CE + RoHS. Australia → SAA. Middle East → TUV or SASO.

Step 4 — Calculate ROI: Energy savings = (old wattage − new wattage) × hours/year × $/kWh.
Typical payback period with utility rebates: 1–2 years. Without rebates: 2–4 years.

Step 5 — Request samples: Always test samples before bulk orders. Verify lumen output,
color temperature, CRI, and compatibility with existing fixtures.
