Bottom line: if your search is “how many amps does a LED light bulb use,” here is the short answer: a standard 9W LED bulb pulls about 0.075 amps at 120V, and a 15W LED bulb pulls about 0.125 amps. But that is not the number that should worry you. In my experience as the person who buys lighting for a 300-person company, the number that actually causes panel issues is inrush current from switching on dozens of LED drivers at once. Wattage tells you what a bulb will cost to run. It doesn’t tell you why a breaker trips when someone hits the master switch.
I’ve been managing facilities purchasing for about four years now—roughly 1,200 bulbs and fixtures, maybe 1,150, I’d have to check the spreadsheet. I took over this role in 2021, and my first lighting project was a full retrofit of our office corridors. I assumed the biggest issue was brightness. It wasn’t. The biggest issues were load calculations, dimmer compatibility, and spec sheets.
Why the amp question is the wrong question
The amp draw formula is easy: amps equals watts divided by volts. A 9W bulb at 120V is 0.075A. At 277V, which is common in commercial lighting, the same 9W bulb draws only 0.032A. That math is useful for estimating how many bulbs you can put on a circuit. But LED drivers are not ideal resistors. They have power factor, inrush current, and harmonic distortion. A driver-rated fixture can pull 10–20 times its running current for a few milliseconds when it powers up. That is why a row of LED fixtures can trip a breaker even when the steady-state load is well under the limit.
For a quick ballpark, running amps at 120V look like this:
- 5W LED bulb: about 0.042A
- 9W LED bulb: about 0.075A
- 12W LED bulb: about 0.1A
- 15W LED bulb: about 0.125A
For continuous loads, the National Electrical Code generally limits a circuit to 80% of its rated capacity. On a 15A breaker, that means 12A of steady-state load, not 15A. In our 2024 parking-garage retrofit, each circuit went from 12.1A to 2.8A after swapping old metal halide fixtures for LED drivers. I checked the clamp meter readings myself. So no, LED bulbs are not the load problem. The duty cycle is not the problem either. The spec sheet is where you find the real story.
GE Lighting and Current Lighting GE: what the names mean
Here’s where the brand name gets confusing. The GE Lighting name still appears on lots of products, but the commercial and industrial side of the business is now marketed as Current Lighting. On many spec documents you will still see “Current Lighting GE” because the brand transition isn’t completely clean. If you are ordering under-cabinet lighting, recessed fixtures, roadway lights, or sports lighting, you will probably be reading Current Lighting GE spec sheets. If you are buying consumer LED bulbs, the GE Lighting brand is still the one on the shelf. Same heritage, different supply channel.
Zigbee PDF files: ask for them before you fall in love
When someone asks me about smart lighting controls, I tell them the same thing: get the Zigbee PDF spec sheet before you choose anything. The first time I compared two similar smart fixtures, the product pages looked identical. The Zigbee PDF told me one supported a maximum of 20 devices per network and the other supported 50. That is the difference between a boardroom that works and a boardroom that requires a reboot every Tuesday. Dodged a bullet when I requested the PDF for a 200-fixture order; the product page didn’t mention the inrush current, and that spec changed the circuit design.
GE Lighting’s Cync line and Current Lighting GE’s commercial systems both use Zigbee-based protocols for device-to-device communication. The PDF will also list whether it supports Zigbee 3.0, what controllers work, and how the dimming curve behaves with standard phase-cut dimmers. I made the mistake of skipping the PDF once, and we ended up with buzzing in the conference room lights. (Should mention: the buzzing was a dimmer mismatch, not a bulb defect.) For me, a missing Zigbee PDF is a red flag. It means the vendor isn’t ready for a commercial buyer who actually reads specs.
Chandelier lighting: where this advice starts to bend
A lot of the same electrical principles apply if you’re looking at chandelier lighting, but the buying process is different. A chandelier is a fixture, not a retrofit. For our lobby, I spent way more time on finish, scale, and lamp shape than on amp draw. GE Lighting makes candelabra-base LED lamps that fit many chandeliers, and those lamps will have the same low amp draw—roughly 0.04 to 0.08 amps per bulb depending on wattage. But if the chandelier itself is the decoration, don’t let energy efficiency be the only factor. Anyone who tells you otherwise is selling hours of warranty calls.
So yes, you can use LED bulbs in chandelier lighting. But the reason to choose a chandelier is rarely about amps. It’s about how the light looks, how the metal feels, and whether the person who approves the budget nods when they see it. That part doesn’t show up on a spec sheet. Simple.
Honest limitations: what I recommend and what I don’t
Now, the part that isn’t about lighting. Every so often, our referral logs show someone landing here after searching “GE dishwasher not lighting up.” I can’t help with that. GE dishwashers are appliances, not lighting products. If the control panel is dark, the problem is usually the door switch, control board, or a failed display module—completely different troubleshooting path than a fixture that won’t light.
On lighting itself, I’ll be straight: GE Lighting and Current Lighting GE are solid choices for most commercial projects, but they are not the only choices. If your priority is a specific aesthetic or a tight budget, you’ll need to compare against other brands. I recommend GE for reliability and spec availability, not because it is the cheapest. The best solution depends on your building’s electrical system and your internal customer’s demands. No single brand is a no-brainer for every project.
Also, before I make any recommendation, I check three things: the fixture’s spec sheet, the dimmer compatibility list, and the electrician’s load calc. In that order. If you’re in the middle of a new construction project, get the electrical engineer involved before you fall in love with a product. A 5-minute amp calculation at the start saves a lot of “can we squeeze it on this circuit?” later.
If you’re dealing with residential chandelier lighting, a GE dishwasher, or a one-off lamp replacement, this article is probably not for you. That said, if your job is anything like mine—buying lighting for real commercial spaces where the panel schedule matters more than the pretty render—start with the amp math, then read the Zigbee PDF. It sounds boring. It saves serious money.
