When you need a ring-shaped fluorescent lamp instead of the standard linear tube, you pick up patron circular fluorescent tubes t5 because they fulfil more than just brightness – they match fixture geometry, socket type and ambient conditions. These aren’t generic tubes; for real installations you’ll dive into diameter, base, life hours, lumen output and compatibility.

T5 ring format – what “patron t5 ring lamps” mean in practice

The term “T5” in this context signals a tube diameter of approx. 16–18 mm and a ring or circular form factor rather than linear. For example, one model: 55 W, ring diameter 302 mm, luminous flux ~4 400 lm, socket 2GX13, colour 3000 K.
Another: 60 W, ring diameter 379 mm, flux ~4 800 lm, same 2GX13 base.
Important when you’re specifying:

Ring outer diameter (e.g., 302 mm or 379 mm) must match fixture recess.
Socket type – many ring lamps use 2GX13. For example the 40 W model uses 2GX13
Colour temperature (3000 K, 4000 K) and CRI (80-89) which influences category “general office”, “warm hospitality”.
Rated life hours – many of the Patron circular T5 rings are ~12 000 h.

Fixture & installation implications for “patron circular fluorescent lighting”

When you choose patron circular fluorescent lighting, you must coordinate fixture features with the tube:

Depth clearances: the ring tube needs proper clearance behind the diffuser to avoid heat buildup which can reduce life.
Mounting geometry: ensure the fixture’s circular reflector or diffuser aligns to ring diameter so light distribution is even.
Electrical compatibility: confirm your ballast or driver supports the T5 ring format (e.g., for 2GX13 base). Mismatched ballasts or sockets cause early failure.
Maintenance access: future replacement should allow removing the ring without heavy fixture dismantle; easier logistics for B2B maintenance.

Procurement & stock logistics for ring tube installations

When ordering batches of Patron circular ring tubes for projects:

Order full zone quantity at once to avoid shade/flux variation between batches. For example one lot: 55 W/3000 K ring diameter 302 mm.
Packaging typically 10-20 pieces per box; MOQ from vendor may apply (e.g., 10 units for some models)
Keep spare inventory (2-3 % extra) for replacements to maintain visual consistency.
Track EAN/MPN codes and batch dates so that later replacements match original run.
From a distributor’s viewpoint ensure you get full spec sheets (tube diameter, base, wattage, flux, life hours) – Patron’s data sheet shows for a 22 W ring: flux ~1 800 lm, diameter 230 mm, lifetime ~12 000 h
