Plan for Ambient Lighting
Don't underestimate the amount of ambient lighting you'll need, especially if your wedding continues after dark. Consider lighting for the parking areas and pathways leading to and from the main event space. You may also want to add decorative lighting to these areas, which will increase your power requirements.
Manage Power Draw
Some appliances and equipment draw more power than others. For example, catering equipment like food warmers and coffee makers typically require 10 amps each. DJ equipment and sound systems can also draw a significant amount of power, with the average DJ setup requiring around 10 amps or 1 kilowatt. Be sure to discuss power requirements with your vendors to ensure you have enough power allocated for each area.
In summary, powering decorative lighting for a wedding requires careful planning and consideration of your specific needs. By calculating your power requirements, choosing an appropriate power source, and managing power draw, you can ensure your lighting enhances the ambiance of your special day without any electrical hiccups.

Powering catering equipment
Determining Power Requirements:
Firstly, create a comprehensive list of all the catering equipment that will require power. This may include items such as food warmers, coffee makers, refrigerators, blenders, and any other appliances used by the catering team. Each appliance should be listed along with its wattage or amperage requirements. This information can be obtained from the equipment manuals or by contacting the manufacturers.
Calculating Total Wattage:
Once you have the power requirements for each appliance, calculate the total wattage needed for all the catering equipment. Add up the wattage values for each appliance to get the total power requirement. It is advisable to have a generator with at least double the capacity of your calculated total to ensure you have sufficient power throughout the event.
Choosing a Suitable Generator:
After determining the total wattage, it's time to select an appropriate generator. Generator hire companies typically offer generators with a baseline capacity of 15 to 20 amps or 2000 watts for basic outdoor wedding needs. However, scaling up to a larger generator or multiple generators may be necessary, depending on the number and power requirements of your catering equipment.
Efficient Lighting and Catering Options:
To reduce the overall power requirements, consider using energy-efficient LED lighting, which consumes significantly less power than traditional incandescent bulbs.

Powering music and sound
Understanding Wattage and Sound Systems
Firstly, it's important to understand what wattage is and how it relates to sound systems. A watt (W) is a unit of power that measures the rate of energy production or consumption. In audio systems, wattage indicates the power output of an amplifier, which determines the potential volume and sound clarity. The relationship between watts and volume is logarithmic, meaning that a 3 dB increase in volume requires doubling the wattage.
Determining Wattage Needs
The wattage requirements for a wedding depend on various factors, including the size of the venue, the number of guests, the type of music, and whether the event is indoors or outdoors.
- For indoor weddings, a good rule of thumb is to have a minimum of 5 watts per person.
- For outdoor weddings or if a louder "rave volume" is desired, consider doubling the wattage to 10 watts per person.
- For context, a single Bose 802 speaker with 91 dB/w sensitivity requires 13,000 watts to produce 132 dB at 1 meter, whereas a Funktion One R3 speaker can achieve the same sound level with only 500 watts due to its higher sensitivity.
Equipment Considerations
When powering music and sound for a wedding, it's essential to consider the equipment needed, such as:
- PA system with sufficient wattage and channels (e.g., aux-in for an iPod or similar device)
- Microphones, cables, and stands
- Monitors for singers or performers to hear themselves
- Stands for PA speakers
- DJ software, if applicable
- Subwoofers, especially for bass-heavy music or outdoor venues, with a common ratio of 2:1 between subs and tops
Example Scenarios
To illustrate the wattage requirements for a wedding, let's consider some examples:
- For a wedding with 100 guests, you would typically need 400-500 watts of amplification for adequate sound coverage.
- A wedding DJ mentions using a 1000-watt generator for lights and the DJ booth, and a 2000-watt generator for the sound system, which is often more than enough.
- For a wedding with 120 guests, a Yorkville Stagepas 500 with 500 watts total can be sufficient, depending on the music genre and venue size.
Additional Tips
- Consider the sensitivity rating of your speakers. Higher sensitivity speakers (90 dB or higher) can produce louder sounds with lower wattage.
- Ensure that your speakers are amplified efficiently. Modern active speakers can help prevent issues with underpowered or overpowered amplifiers.
- If possible, hire a professional or an experienced friend to handle the sound system to ensure optimal sound quality and avoid technical issues during the event.
In conclusion, powering music and sound for a wedding requires careful consideration of wattage needs, equipment, and other factors to ensure a memorable and enjoyable experience for the couple and their guests.
