Beleuchtungsbedürfnissen gerecht zu werden.
Wie die klassischen T8 Leuchtstoffröhren, so weisen auch unsere T8 LED-Röhren bis zu einer Länge von 105 cm einen standardisierten Durchmesser von 26 Millimetern auf. Allerdings unterscheiden sich die Längen dieser Modelle je nach der jeweiligen Leistungsaufnahme. Hier in der Kategorie T8 LED Röhren bis 105cm sind längere LED Röhren mit einer moderaten Leistungsaufnahme zu finden. Sowohl bei den Modellen mit 100cm Länge, als auch bei den Modellen mit 105cm Länge liegt die Leistungsaufnahme bei 15 Watt. Je nach Modell und Hersteller wird damit eine Lichtleistung im Bereich von 830 bis 865 Lumen erreicht. Die LED Leuchtmittel sind somit als Ersatz von T8 Leuchtstoffröhren mit 36 Watt bzw. mit 38 Watt geeignet, die eine gleichwertige Lichtstärke erreichen.
In unserem Onlineshop finden Sie auch LED Röhren in anderen Längen und Leistungsstufen:
Der Abstrahlwinkel stellt ein markantes Unterscheidungsmerkmal zwischen LED Röhren und herkömmlichen Leuchtstoffröhren dar. Im Gegensatz zu Letzteren, die das Licht in einem ungerichteten 360-Grad-Winkel verteilen, ermöglichen LED Röhren eine gezielte Beleuchtung des Bereichs unter der Lampe. Unsere T8 LED Röhren bis zu einer Länge von 105 cm bieten einen Abstrahlwinkel von 200 bis 300 Grad, was zu einem konzentrierten Lichtstrahl und verbesserten Lichtleistung führt. Alle T8 LED-Röhren sind mit einem G13 Stecksockel ausgestattet, welcher speziell für den Einsatz bei Leuchtstoffröhren entwickelt wurde. Dieser Sockel, mit zwei Kontaktstiften im Abstand von 13 Millimetern, unterscheidet sich von den T5 LED-Röhren, die mit einem kleineren G5 Sockel bestückt sind.
Bei der Verwendung von T8 LED-Röhren mit einer Länge von bis zu 105 cm in einer herkömmlichen Halterung für Leuchtstoffröhren, die mit einem konventionellen (KVG) oder verlustarmen Vorschaltgerät (VVG) ausgerüstet ist, ist der Austausch des bestehenden Starters gegen einen sogenannten Dummy-Starter erforderlich. Dieser Dummy-Starter dient hauptsächlich dazu, den Stromfluss zu gewährleisten, indem er die notwendige elektrische Verbindung herstellt.
T8 LED Röhren bis 105cm in verschiedenen Varianten
In unserem Onlineshop finden Sie ein breites Angebot an günstigen T8 LED Röhren bis 105cm in verschiedenen Varianten:
In unserem Angebot finden Sie T8 LED Röhren mit einer maximalen Länge von 105cm in einer Vielfalt von Farbtemperaturen. Modelle in warmweiß, die eine Farbtemperatur von circa 2700 Kelvin aufweisen, schaffen eine warme und einladende Atmosphäre. Die neutralweißen Varianten mit einer Farbtemperatur von etwa 4000 Kelvin bieten hingegen ein klares und ausbalanciertes Licht. Für Umgebungen, in denen ein besonders helles und die Konzentration förderndes Licht bevorzugt wird, eignen sich letztendlich die kaltweißen oder tageslichtweißen Modelle, die eine Farbtemperatur im Bereich um die 6500 Kelvin aufweisen.
Lassen Sie sich bei der Auswahl passender T8 LED Röhren bis 105cm aus unserem Onlineshop Sortiment individuell beraten. Gerne unterstützen wir Sie auch beim Wechsel auf moderne LEDs. Unser professionelles Verkaufsteam steht Ihne $group_name;
