T5, T8, & Fluorescent Group Relamp

Some of our lamps out, they don’t seem to be as bright as when we first converted and other fixtures don't work at all.

ROI Energy provides what’s referred to as a “Group Relamp Project”. This is where we typically come in after hours and replace ALL the T5 or T8 lamps in your fixtures. 

• This can be for fluorescent high bay fixtures in a manufacturing company or warehouse.
• It can also be done for office 2x2’ and 2x4’ recessed ceiling mounted troffer fixtures.
• Weekends and “off-shifts” are a good time to do this work so we don’t interrupt your production.
• Since we buy thousands of lamps and ballasts direct from the manufacturers, we have excellent prices on quality brand products.

All lamps have an average rated lamp life based on hours of operation. When your lamps begin to reach their “end of life cycle” they begin to diminish in lumen (light) output or just go out.  It becomes unproductive to try to replace these just a few at a time, especially when there are hundreds or thousands of lamps in a facility.

ROI Energy is extremely competitive when it comes to group relamp projects.  While we are at it, this is the time to replace any ballasts which are no longer working.  You’ll notice night lights which may be on 24X7, tend to have ballasts out due to their “always on” status.

We install Philips or GE long life lamps and GE ballasts.  Our lamps are high quality, long life lamps, typically rated at 36,000 hours so you don’t have to relamp as often. Defective ballasts typically are determined after we replace the lamps and the lamps don’t illuminate.

Group Relamping: Replacing all lamps at once

Replacing all lamps in a space at the same time, even though most haven’t burned out, often provides multiple benefits

At many facilities, when a lamp burns out, all the following steps are taken as part of spot relamping. A technician determines the lamp type, possibly by a visit to the site, gets a lamp, carries a ladder to the site, opens the fixture, replaces the lamps and then arranges for disposal.

The entire process may well distract employees near the lamp. And without close oversight, the last step is often truncated by simply dropping the lamps into the nearest dumpster where they are quickly covered — and probably smashed — by other trash, releasing their mercury. The labor involved in this process may be a significant hidden cost, especially when compared to alternatives.

Most lamp manufacturers and lighting maintenance firms recommend changing lamps before they burn out, with good reason. While perhaps a bit counterintuitive, doing so greatly reduces labor wasted on spot relamping, reduces workplace disruption and better controls lamp disposal. Lamps are replaced en masse (usually during off hours) as they approach about 60 to 70 percent of their rated lives, which is when roughly 10 percent may have burned out and before failure rates begin to climb.

Such group relamping is often done by crews whose main focus and experience is time-efficient fixture maintenance because they are paid on a piece rate basis. Trained in proper lamp disposal, they take responsibility for off-siting and documenting removed lamps.

How Often?

While lamp lives vary, group relamping cycles for linear fluorescent lamps are often spaced about four to five years apart. Group relamping may be sequenced floor-by-floor, or done for an entire building, as desired to accommodate operations, crew size, etc. Lamps are gathered and disposed of in large groups, simplifying compliance with environmental regulations — which, for mercury, are becoming tighter.
