Q1: What is the Aleddra Self-Testing Emergency LED Tube?
The Aleddra Self-Testing Emergency LED Tube is a dual-mode LED tube that functions as both a regular light source and a built-in emergency light during power outages. It automatically switches to emergency mode and provides illumination for up to 90 minutes using its internal battery.
What sets Aleddra apart is its self-testing feature, which automatically runs a 30-second monthly test and a 90-minute annual test—no human intervention required.
Q2: Can Aleddra’s “lockable” socket be used with non-PRO emergency tubes?
Yes. Aleddra’s lockable socket can be used with non-PRO model tubes, but it must be ordered as a separate line item.
Q3: How does the Aleddra Self-Testing Emergency Tube schedule its monthly and annual self-tests?
Once installed, the tube automatically sets its test cycle based on the installation time.
For example, if the tube is installed at 1:00 PM, both the monthly and annual tests will be scheduled to begin at 1:00 PM.
You can reset the test cycle by holding the test button for 6 seconds at a new time—e.g., press and hold at 8:00 PM to reschedule future tests to begin at that time.
Q4: If the Aleddra Self-Testing Emergency Tube fails a test, what happens?
If the tube does not pass its self-test, the LED indicator light will flash rapidly and continue flashing until the faulty tube is replaced. This provides a clear visual alert that maintenance is required.
Q5: How do third-party emergency tubes handle testing?
Third-party emergency tubes typically rely on manual testing. Here’s how they work:
- The user must manually push a test button to start the cycle.
- Most cannot distinguish between a 30-second test and a 90-minute test.
- Unless the test is manually stopped, the tube will run the full 90-minute test every time, even monthly.
This can drain the battery prematurely, leading to shortened lifespan and failure to meet the emergency runtime during the product’s warranty period.
Q6: What does a customer need to do to test competitor emergency tubes?
Most third-party tubes require customers to:
- Turn off the breaker controlling the emergency fixtures, OR
- Use a ladder to access and press the test button, OR
- Use a stick to reach the button if the fixture is open, OR
- Use a remote device to trigger the test
Then, the user must:
- Time the test for 30 seconds or 90 minutes
- Manually stop the test to avoid a full 90-minute cycle
If the test isn’t stopped, the tube will run the full duration—damaging battery life and increasing maintenance risk.
Q7: What does the customer need to do to test an Aleddra Emergency Tube?
Nothing at all.
With Aleddra’s Self-Testing Tubes (G3PLUS, G4, and G4PRO Series):
- The tube automatically runs the 30-second monthly test and 90-minute annual test
- The indicator LED will alert you if the tube fails
No ladders. No breaker shutdowns. No manual timing.
This patented self-testing feature ensures code compliance, operational reliability, and reduced labor costs.
Q8: I have a customer looking for a 4ft emergency LED tube that works with a motion sensor. Will the Aleddra LLT-4-EM-T8-G3PLUS-15W-50K work in this case?
No, the G3PLUS model is not compatible with motion sensors.
However, the G4 EM T8 is motion sensor compatible.
The recommended part number is: LLT-4-EM-T8-G4-15W-3CCT
Wiring Instructions:
- Red-labeled endcap: Connect to a constant-on circuit (L and N) to charge the internal battery.
- White endcap: Connect to a switched circuit (L and N) controlled by the motion sensor.
