For the registered set of 10 LED bulbs, use 115 W (range 80–150 W) as the running-power planning value. The registered starting entry is 115 W (range 80–150 W).
For this load by itself, the tool’s planning result is 144 W running, 115 W starting. The generator must satisfy both ratings; in this result, running capacity is the larger requirement because the registered non-motor load has no additional starting-watt allowance above its running value.
This is a low-confidence estimate for one set of 10 lights in the registered 120 V AC class. It is not a measurement of your bulbs or proof that a particular generator and lighting system are compatible.
Registered lookup data
| Field | Registered value or condition |
|---|---|
| Appliance class | LED lights (10 bulbs) |
| Quantity | One set containing 10 bulbs |
| Supply class | 120 V AC |
| Running power | 115 W (range 80–150 W) |
| Starting power | 115 W (range 80–150 W) |
| One-load generator result | 144 W running, 115 W starting |
| Confidence | Low; planning typicals, not a model specification |
| Daily energy | Not supplied |
This lookup covers the registered AC lighting class only. It does not cover DC camping lanterns, battery charging, portable power station charging, or a different number of bulbs.
What the wattage range means
The typical value and range describe a generic set of 10 LED bulbs in the registered BGT 1.2.2 dataset. The range reflects variation within that appliance class, but it is not a measured range for your installation.
Running watts are the power required while the lights operate. Starting watts are the power considered when the load is switched on. In this registered non-motor case, the running and starting entries are equal. That does not mean starting power is unknown or zero, and the starting value is not extra energy consumption.
Because the exact bulb, fixture, or LED-driver model is unknown, use this range for preliminary planning only. Use the installed equipment’s watt ratings when they are available.
Running watts are not daily energy use
Watts (W) measure power at a particular time. Watt-hours (Wh) measure energy used over a period. To estimate daily energy, you need both the actual operating power and the number of hours the lights are on:
Daily energy (Wh) = power (W) × operating time (hours per day)
This lookup does not supply a daily operating schedule or model-specific power measurement, so it cannot report Wh per day. Running watts alone must not be presented as daily energy. If groups of lights operate for different lengths of time, calculate each group separately and add the resulting Wh values.
How to find the rating for your lights
For a more reliable total:
- Identify every light that will operate at the same time. Keep essential lighting separate from optional decorative, outdoor, or seldom-used lighting.
- Look for an input-watt rating. Check each bulb, integrated fixture, LED driver, package, or manufacturer document. The value may appear as “W,” “watts,” or “input power.”
- Add the watt ratings. If 10 identical bulbs each have the same input-watt rating, multiply that rating by 10. For mixed bulbs or fixtures, add their ratings individually.
- Include other simultaneous loads separately. A refrigerator, furnace controls, internet equipment, and other outage loads are not included in this lighting result.
Prefer a listed watt rating when available. If a label provides only volts and amps, multiplying V × A does not necessarily give the real wattage of an AC LED load without the relevant power-factor information. If the watt rating remains unknown, keep it marked as unknown rather than entering zero.
What the generator result does not verify
The one-load result is a capacity-planning envelope. For this bound calculation, the tool divides running watts by 0.80 and considers one start. That is the method used for this result, not a universal generator-sizing rule.
The result does not verify a generator’s receptacle, voltage quality, waveform, grounding, wiring, transfer equipment, or compatibility with a particular LED driver or dimmer. It also does not model other loads running at the same time, electrical dispatch, fuel consumption, or runtime.
The binding identifies an upstream wattage-chart URL, but no retrieved document or excerpt was supplied for this page. We therefore report the completed engine result with its low-confidence qualifier rather than presenting that external source as independently checked.
Before connecting lighting, confirm that the generator output and connection method satisfy the lighting equipment’s requirements. Use a qualified electrician for permanent wiring or transfer-equipment work.
Next step for outage planning
For the simplest planning path, first total the essential lights you expect to use together. Then add every other appliance that must run at the same time in the Generator Size Calculator for Home. Loads that can take turns should be scheduled separately instead of automatically being counted as simultaneous.
