For standard 5mm diameter LEDs the maximum **current** is usually 20mA, so 10mA or 15mA are suitable values for many circuits. The **current** must be in amps (A) for the calculation, to convert from mA to A divide the **current** in mA by 1000.

Simply so, Do LED bulbs draw less amps?

Yes, **LED bulbs** use **less** power than incandescent **bulbs**. Therefore you should have power to spare.

**Can I use 2.5 mm cable for lighting?**

I don’t think it is that you **can**‘t **use2.5mm**^2 **cable for lighting**, just that it is rarelynecessary. 1.5mm^2 **cable** is rated at 14.5 amps continuousunder typical installation conditions. At 240 volts, that is acapability of 3.5 kilowatts. There just doesn’t seem to be any needto **use** it for domestic **lighting**.

**How many amps does a 1000 watt LED grow light draw?**

**Can you put lights and outlets on the same circuit?**

The **outlet receptacles** must be served by a 20-amp**circuit**. The **same circuit can** supply the entirebathroom (**outlets** plus **lighting**), provided there areno heaters (including vent fans with built-in heaters) and providedthe **circuit** serves only a single bathroom and no otherareas.

**How many watts does a TV use?**

**How many amps does 1500 watts draw?**

**How many outlets can be on a 15 amp breaker?**

As a rule of thumb in counting devices on a circuit youcount each **outlet** (light or receptacle) as 1.5 **amps**.Now remember you only count 80% of the rating which means a **15amp breaker** should not exceed 12 **amp** load, a 20 **ampbreaker would** be 16 **amps**.

**What wire do you use for lights?**

In practice, most **lighting** circuits arecontrolled by a 15 amp circuit breaker, and therefore 14 gauge**wire** is acceptable. Circuits with power outlets are oftencontrolled by 20 amp breakers and should be wired with 12 gauge**wire**.

**How many LEDs can be on a 20 amp circuit?**

You can put up to 30 lights (based on 50 watt light) on a **15** amp breaker. You can put up to 40 lights (based on 50 watt light) on a 20 amp breaker.

**What voltage do LED lights run on?**

Typically, the forward **voltage** of an **LED**is between 1.8 and 3.3 volts. It varies by the color of the**LED**. A red **LED** typically drops 1.8 volts, but sinceboth **voltage** drop and **light** frequency increase withband gap, a blue **LED** may drop from 3 to 3.3volts.

**How many amps does a 4 foot LED light draw?**

The Feit **4**‘ **LED** shop **lights draw** about 0.3**amps** each according to the manufacturer. 6 times . 3 **amps** is only 1.8 **amps**, round up to 2. You are obviously well within the capacity of a 20 **amp** breaker.

**How do I know what size fuse to use?**

**Fuse rating = (watts/volts) x 1.25**

- Note the power of the appliance – usually in theappliance manual,
- Note the voltage (240 volts in the UK).
- Use the next highest fuse rating after the calculation. Say thecalculated fuse rating is 2.2679 amps, use a 3 amp fuse.

**How many outlets can be on a 15 amp circuit?**

**How many outlets can be on a 15 amp circuit?**

A **1000w** HPS or Metal Halide **light** takes 9**amps** at 120 volts so you **can** only run one on a walloutlet circuit. A standard dryer outlet **is** 220 volts and 30**amps** so you **can** power up to six **1000 wattlights** on that circuit.

**How many watts is 90 amps?**
