Qual è la differenza tra tubi LED T8 e T5?

I tubi T8 hanno diametro 26mm attacco G13 — la sostituzione più comune per armature TL8. T5 ha diametro 16mm attacco G5 per armature slim, illuminazione undershelf e high-bay.

Cosa significano Tipo A, B e A+B?

Tipo A funziona con il ballast esistente. Tipo B (bypass) rimuove il ballast per massima efficienza (L70 ≥ 50.000h). Tipo A+B supporta entrambi.

Quali certificazioni hanno i vostri tubi LED T8?

CE (UE), RoHS, TÜV. SAA, SASO su richiesta. Documentazione inclusa in ogni ordine.

Qual è il quantitativo minimo d'ordine (MOQ)?

MOQ standard: 100 pz per SKU. OEM/private label: da 500 pz. Campioni 5–20 pz disponibili.

Potete produrre tubi LED T8 personalizzati?

Sì. OEM/ODM: CCT personalizzato (2700K–6500K), CRI (80–98), SPD per retail alimentare, medicale e illuminazione circadiana.
