How Long Will a Rechargeable LED Module Run?

Customers ask for useful light and long working time together.

Two separate historical customer enquiries show why this matters. One light-ball buyer wanted the product to be as bright as possible, with a strong battery for long-lasting operation. Another customer wrote:

“so i am afraid that 1000 mAh is not enough for the battery”

These are real buying concerns, not test results. The first buyer wanted both brightness and duration; the second worried that the battery capacity might be insufficient. Neither enquiry, by itself, tells us the power demand or confirms a particular number of operating hours.

The practical response is to define the required light setting, product housing and working duration before choosing a battery or promising runtime. The customers' identities are withheld, and these enquiries do not validate the reference figures below.

VC-LN120 · 4400mAh · white-light mode

One observed result, with two engineering estimates.

The following reference combines a Vcan-confirmed actual test result with two estimates confirmed by Vcan engineering. Each figure keeps its evidence label so you can distinguish what was observed from what still needs validation in your own product.

These are configuration-specific references, not guaranteed runtimes for every VC-LN120. Brightness percentages describe reference control settings, not calibrated percentages of visible light output. The 15-hour and 40-hour estimates are not additional measured results; confirm the selected configuration and test conditions before production.

The point is not to advertise the longest figure without its setting. A 40-hour engineering estimate at low brightness does not mean the module runs for 40 hours at maximum brightness. Likewise, the eight-hour observation should not be transferred to a different LED layout, battery version or operating mode.

Will a different colour work for longer?

With the same battery configuration and brightness setting, some single-colour modes are expected to run longer than white-light mode. This is an engineering expectation, not a separate set of colour-runtime tests. Actual runtime varies by colour and control settings.

Do not estimate a red, green or blue runtime by simply counting how many colour channels are on. The VC-LN120 reference platform has RGB and dedicated white LEDs, so its white-light setting must not automatically be treated as red, green and blue operating together. The selected LED layout and control program need to be considered.

If your event mainly uses one colour, specify that colour and the intended brightness in the sample brief. If white light is essential, assess the white-light setting itself rather than using a coloured-light result. The white-only and RGBW guide helps define the light configuration.

Need a longer evening: lower brightness or a larger battery?

First check whether maximum brightness is necessary.

Try the module inside the actual PE, acrylic or glass housing. A medium setting may provide the appearance your customer needs, making it a useful starting point for a longer-duration brief. It still needs testing: the medium-setting estimate above is not a promise that every finished lamp will deliver 15 hours.

If high brightness is essential, review the complete configuration.

Ask Vcan to review battery space, LED configuration, required duration and charging equipment together. A larger battery can be a development option, but it is not an isolated substitution or a reason to scale all runtime figures directly from mAh.

The existing VC-LN120 6000mAh long-runtime project documents a separate custom configuration and colour tests. It is useful development evidence, not a controlled battery-only comparison with the 4400mAh white-light reference here. Review the separate battery and matching charging arrangement when changing the specification.

Keep another customer's result in its own context.

A separate under-table lighting buyer reported about 8.5 hours per charge. That is valuable feedback for event planning, but the surviving record does not establish the battery, brightness and mode needed for a direct comparison. It is not another measurement of the 4400mAh configuration above.

Turn “all-night lighting” into a specific sample requirement.

• Working duration: the hours the product needs to remain useful, including your setup and event schedule.
• Light setting: white or selected colour, intended brightness and whether the setting remains fixed.
• Finished product: housing photos or drawings, installation opening, available depth and the appearance required through the shell.
• Configuration: module version, battery, controls and specified charging equipment.
• Validation: record how the sample was charged, the settings used, test duration and the reason for ending the trial.

Agree what counts as a usable result: a lamp still emitting light is not necessarily bright enough for its intended job. Use the sample testing checklist to record accepted results, requested changes and anything not yet tested.
