Why Switch To

LED T8 Tube Lights

Energy Savings

It's difficult for property managers to realize the potential savings LED tubes have over their conventional fluorescent tube counterpart when just looking at a singular lamp’s specifications. Proper calculations require looking at fluorescent bulb wattage and the ballast factor to determine a true operational wattage. Then multiply that by the amount of bulbs per fixture and how many of those fixtures the facility is equipped with along with standard operation time. Fluorescent lamps generally get installed in places that require 24/7 operation time. This is over $5,000 in energy savings a year for a facility with 100 fluorescent fixtures with standard fluorescent to LED tube relamping specifications.

Reduced Maintenance Cost

One of the greatest benefits from LED lighting conversions of linear fluorescent lamp systems is the savings that can be achieved due to reduced maintenance costs with LEDs. Typical linear fluorescent fixtures require constant maintenance, inventory and records of all components; including the bulbs themselves, ballasts, and starters. LEDs are versatile in their dependency with that existing system allowing them to operate as “Plug and Play” with an existing ballast or with direct line bypassing a bad ballast. Combine that versatility with a minimum L70 lifetime of 50,000 hours and you will see quickly that the near zero maintenance could be the greatest benefit of all.

Rebate Incentives

Linear fluorescent lighting is one of the most consistently available retrofit rebate incentives offered from most all power utility companies for commercial and residential users. Most all LED tubes are listed under specific categories of DLC to help guide the end users and the utility companies to the most applicable product for their applications. The average rebate incentive for fluorescent lighting conversions to LED can cover up to 80% of the upfront cost of the light itself.

Key Technical Considerations

Connection Types

Single Ended

Electrically connected from one end of the tube, one pin connecting to line and one to neutral. This type requires non-shunted sockets and rewiring

Dual Ended

Electrically connected on both ends of the tube, with one end connecting to line and one to neutral. This type can use shunted or non-shunted sockets. As with the original bulbs these are replacing, one end of the tube connects to L and the opposite end to N—one end should not be connected to both.

Ballast Compatibility

Ballast In-Line

Dual-End Type A installation is “Plug and Play” and simply replaces the original fluorescent tube with an LED equivalent, requiring the use of the original ballast. This is the easiest solution to relamping your fixture if you have already determined your ballast is functioning properly.

Ballast Bypassed

Single-End Type B installation requires bypassing the original ballast and rewiring sockets (tombstones) in the fixture. This is a popular solution when relamping, due to the likelihood of an eventual ballast failure.

Socket Wiring

Shunted

Both contacts in the same socket (tombstone) are connected/bridged and are the same polarity—either L or N.

Non-Shunted

Contacts in the same socket (tombstone) are split, but can be either the same polarity or opposing polarity depending on the way the socket (tombstone) is wired.

Determining Shunted or Non-Shunted

Below are some typical examples of how shunted or non-shunted sockets might look. You should always check the socket terminals with a multimeter before installing bulbs or rewiring. If the two sides of a socket have continuity, then the socket is shunted regardless of appearance.

Types Of T8 Tubes

 

Type A Dual-End

Installation is “Plug and Play” and simply replaces the original fluorescent tube with an LED equivalent, requiring the use of the original ballast.

  • Plug and Play
  • Dual-End wiring
  • Requires compatible ballast
  • Shunted or non-shunted sockets
Shop Type A Dual-End
 

Type B Single-End

Installation requires bypassing the original ballast and rewiring sockets (tombstones) in the fixture. This is a popular solution when relamping, due to the likelihood of an eventual ballast failure.

  • Single-End wiring
  • Requires bypassing the ballast
  • Non-shunted sockets only
Shop Type B Single-End
CURRENT PRODUCT

Type B Dual-End

Installation simply involves bypassing the existing ballast and installing the tube with polarity matching the wiring.

  • Dual-End wiring
  • Requires bypassing the ballast
  • Shunted or non-shunted sockets
Shop Type B Dual-End
 

Type A/B Hybrid

This can be installed in the same manner as a dual-end Type A (“plug and play” tube simply replaces the original fluorescent tube) or a single-end Type B (requires bypassing the original ballast and rewiring sockets).

  • Can be used with or without ballast
  • Ballast bypass (Single-End wiring)
  • Shunted or non-shunted sockets (Type A), non-shunted sockets (Type B)
Shop Type A/B Hybrid
 

Type A/B 3-in-1 Universal

This is the most universal tube lamp solution. “Plug and Play” install if using the existing ballast, or bypass the ballast and install in the same manner as Single-End or Dual-End Type B.

  • Can be used with or without ballast
  • Ballast bypass (Single and Dual-End wiring)
  • Shunted or non-shunted sockets (Type A or Dual-End Type B)
  • Non-shunted (Single-End Type B)
Shop Type A/B 3-in-1 Universal
