Quick answer: size a rechargeable-candle workflow around verified usable runtime, the available charging window and the confirmed number of candles per set. Keep a ready-to-use group separate from the group awaiting charging. Do not turn a headline battery-life figure into a guaranteed number of event shifts.
Begin with one complete operating cycle
Map the work from storage to setup, operation, collection, inspection, charging and the next setup. Identify who is responsible at each handover. This reveals practical questions that a product photograph cannot answer: where the charging base will sit, how staff know which candles are ready, and how incomplete sets are identified before an event.
For WN-CD12, the listed charging base is 28 × 9.6 × 2 cm and the cable is 1 m long. Allocate access space around the base and confirm the power supply specification. Keep the workspace consistent with the manufacturer’s operating instructions; this article does not specify an electrical installation or a charging safety certification.
Use runtime with its conditions attached
The brief lists approximately 2–3 hours of charging and 30–40 hours of runtime. Before planning consecutive shifts, ask which light mode and brightness produced the runtime range. Check the sample at the actual chosen setting. Record a usable endpoint—such as the point where the light no longer meets the agreed visual requirement—rather than treating the final faint glow as usable service.
A planning calculation can be written as verified usable hours divided by hours per operating session. That arithmetic is only a capacity estimate. It does not account automatically for incomplete charging, aging, storage time or variation between candles. Choose an operational reserve after observing the actual sample, rather than inventing a universal percentage.
Do not assume what the charging base accepts
A shared base is useful only when its capacity and contact arrangement match the ordered candles. The current WN-CD12 source materials show a pack-quantity discrepancy, so confirm the final number of candles and charging positions before counting sets. A USB-C cable does not establish compatibility with every adapter. Nor does the presence of a magnetic attachment on a different lamp mean that the products share a charging system.
If you are comparing larger lamp fleets, review the separate JBTD-160 charging-trolley product. Treat it as a different system requiring its own compatible-lamp confirmation—not as a charger for WN-CD12.
Create a visible handover routine
- Count the returned candles against the confirmed set record.
- Check the housings and charging contacts according to the supplied instructions; separate any unit needing review.
- Place the correct units on the correct charging base and check the indicated charging state.
- Record the charge window and inspect the full-charge indication. WN-CD12 is listed to extinguish its red indicator when full.
- Move the approved group to a clearly identified ready area and record any missing or unresolved unit.
Do not instruct staff to open batteries, improvise adapters or continue using a damaged product. Request the relevant operating and service instructions for the final model. No wet-cleaning method or outdoor rating has been verified for the candle set in this guide.
Verify control and scheduling together
After charging, use the intended remote mode in the actual room. A timer setup is useful only if staff understand its cycle and cancellation behavior. The infrared remote and timer test gives a separate record for those checks. This keeps “charged,” “responds to the remote” and “passed the required operating session” as three distinct acceptance states.
Send the event duration, number of placements, turnaround window and required spare-set strategy with your inquiry. Use the sample approval record to keep the agreed workflow attached to the ordered configuration. Discuss a sample-based charging plan.
