Holder Types Explained
- Fixed holders – rigid mounting for standard fluorescent tube fixtures; one end is fixed, the other is spring-loaded for lamp insertion
- Rotating (swivel) holders – allow the lamp to be rotated after insertion for directional T5/T8 LED tube retrofits with internal driver
- Spring-loaded holders – both ends spring-loaded for easy lamp replacement without tools; common in T5 under-cabinet fixtures
- Ceramic PGZ18 holders – high-temperature ceramic body for double-ended halogen tubes operating at up to +350°C near the lamp base
Application Scenarios
- Commercial office & retail lighting – T8 fluorescent troffers, strip lights, and suspended linear fixtures
- Industrial & warehouse lighting – T8 high-output fluorescent and LED tube fixtures in high-bay and low-bay configurations
- Under-cabinet & display lighting – T5 slim-profile fixtures for kitchen, retail display, and museum showcase illumination
- Stage & architectural halogen – PGZ18 double-ended halogen tubes in wash lights, cyclorama fixtures, and architectural wall washers
- OEM luminaire manufacturing – T5, T8, and PGZ18 holders for production-line integration in commercial and industrial fixture manufacturing
- LED tube retrofit – rotating T8 holders for Type B (ballast-bypass) LED tube installations requiring lamp rotation after insertion

Buying Guide – Selecting the Right Lamp Holder
- T5 vs T8 – T5 uses a G5 base (5mm pin pitch); T8 uses a G13 base (13mm pin pitch). They are not interchangeable — confirm the tube diameter and base type before ordering.
- Fixed vs rotating – for LED tube retrofits requiring lamp rotation (Type B), select rotating holders; for standard fluorescent or Type A LED tubes, fixed holders are correct.
- PGZ18 ceramic vs thermoplastic – always use ceramic holders for double-ended halogen tubes; thermoplastic is not suitable for PGZ18 halogen operating temperatures.
- Spring-loaded vs rigid – spring-loaded holders simplify lamp replacement in accessible fixtures; rigid holders provide more secure retention in vibration-prone environments.
- Wire gauge – use 0.5mm²–1.0mm² (AWG 20–18) for T5/T8; use 1.0mm²–1.5mm² silicone wire for PGZ18 halogen applications.
Frequently Asked Questions
What is the difference between T5 and T8 lamp holders?
T5 holders use a G5 base with a 5mm pin pitch; T8 holders use a G13 base with a 13mm pin pitch. The tube diameters also differ (T5 = 16mm; T8 = 26mm). They are not interchangeable — always match the holder to the tube type.
Do I need rotating holders for LED tube retrofits?
Only for Type B (ballast-bypass) LED tubes that require the lamp to be rotated 90° after insertion to align the internal driver pins. Type A (ballast-compatible) and Type A+B LED tubes do not require rotating holders.
Why must PGZ18 holders be ceramic?
Double-ended halogen tubes generate extreme heat at the lamp base, with temperatures exceeding +250°C during operation. Ceramic holders are the only material rated for these temperatures — thermoplastic holders will deform or fail under halogen operating conditions.
Can T8 holders be used with T8 LED tubes?
Yes. Standard T8 G13 holders are compatible with T8 LED tubes. For Type B (ballast-bypass) LED tubes, ensure the holder is wired for direct mains connection and select rotating holders if the LED tube requires rotation after insertion.
Do you offer bulk pricing for OEM luminaire production?
Yes. Yoeruyo offers tiered pricing for orders of 100 units or more across all holder types. Contact us for volume quotations, custom lead wire configurations, and OEM packaging options.
