Since LED lights were introduced, the T8 LED has been developed to give a dependable linear light source. Type A, Type B, and Hybrid LED Tubes exist. Type B T8 LEDs have various advantages over fluorescent bulbs. Let's start with Sunco T8 LED light quality and output.

T8 LED Light Output

With a wide range of colour temperatures, quick on illumination, and high lumen count, the Type B T8 LED Tube offers several advantages over fluorescent tubes.

Sunco T8 LEDs deliver rapid light without waiting for fluorescent tubes to heat up. The T8 LED Tube 18W's 2200 lm lumen count provides powerful illumination for work completion.

Discolouration and brightness loss are not difficulties with LED bulbs. T8s don't degrade light quality.

LEDs offer more colour temperatures, so your office won't be inundated with sickly green light. Sunco T8s come in 4000K (Cool White), 5000K (Daylight), and 6000K (Daylight Deluxe, which resembles silver) to suit your lighting needs.

LED T8s don't degrade light quality like fluorescent tubes. Aged fluorescents dim due to phosphor and mercury loss, which Sunco T8 LEDs lack. Mercury vapour is utilised in fluorescent lamp tubes, which are coated in phosphors. Due to the lack of inert gas inside T8 LED tubes, UV and IR radiation is absent.

Due to their larger lumen count and 110-degree beam angle, Sunco T8s produce more light for the job. Sunco T8s are brilliant and lumen-rich. The 18W T8 LED Tube Clear has 2200 lm of brightness, while the 15W has 1800.

Sunco T8 LEDs have CRI80+ for accurate colour reproduction and clear definition compared to fluorescent tubes. High CRI of 80+ (measured from 0-100) resembles sunlight. T8 Tube-lit items stand out in colour and texture.

Accurate colour rendering may not seem like a major benefit, but humans can recognise false colours in low CRI light. High CRI is useful in task-oriented workspaces or retail spaces that desire to accurately portray clothing and product colours and textures.

LED T8s outperform linear tubes in more than just light quality. Ballast bypasses help too.

 

No Ballast = Energy Savings

The ballast distributes energy to start and operate a fluorescent tube or HID lamp with voltage, current, and waveform. T8 LEDs do not use ballast electricity, therefore removing it saves energy instantly. Each adapted fixture uses fewer watts without a ballast. Think that's inconsistent? With a ballast for each fixture, lighting every floor of a tall office building, warehouse, or other industrial location increases energy usage.

Single end (SEP), direct wire Type B LED Tubes like the Sunco T8 LED were developed to improve energy efficiency and minimise ballast failure and maintenance. T8 Type B LEDs save electricity by bypassing the ballast. This makes Type B LED tubes the most efficient. To perform a ballast bypass and install new non-shunted sockets (tombstones), the retrofit process may take longer than a Type A, but it is worth it, especially with several linear tube fixtures.

Unlike other LED tube types, Type B T8 LEDs do not have ballast compatibility issues with bulbs. Direct-wired Type B bypasses the ballast and supplies line voltage to non-shunted tombstones.

Broken ballasts are replaced regularly. A failed fluorescent tube ballast causes the light to blink rapidly or fade. Direct-wire Type B LED Tubes (SEP) are ballast-free.

The normal fluorescent T8 tube needs to be replaced 3.33 times, but an LED T8 tube just needs one. Another cost-saving benefit of T8 LEDs. End-user savings include lower maintenance and energy expenditures. Especially since T8 LEDs outlast fluorescent lamps.
