WindowCandles System Builder
Build Your Complete System
Follow the 5 steps below to configure and order everything you need for a professional WindowCandles installation. Each step adds items directly to your cart.
Get StartedSelect Your Candles
One WindowCandles Assembly Kit (WCA1) per window — count your windows, that's your quantity.
Count Your Windows
Each window gets exactly one candle kit. A 32-window home needs 32 WCA1 kits. Simple as that.
What's Included
Each kit includes: (1) WindowCandle, (1) 302-CLED Filament LED Bulb, (1) MCA1-N Mounting Clip, and (1) Installation Manual.
Low-Voltage Safety
This is a NEC Class 2 low-voltage system — safe for homeowner use. Always use the specified WC18/2 wire to maintain your warranty.

Select Your Transformers
1 transformer powers up to 15 candles — use the calculator below to find your exact quantity.
The Rule of 15
Every 15 candles requires 1 WC50VA transformer. This rule applies whether you use LED or incandescent bulbs — it's a regulatory requirement, not just a suggestion.
Where to Install
Place transformers near your electrical panel — basement, garage, or utility closet. Central placement makes future management easier and simplifies smart-home integration.
Specifications
Input: 120VAC / 60Hz. Output: 24VAC at 50VA. Max load: 15 incandescent or 50 LED candles per transformer. UL Listed (E508012). Suitable for damp locations.
Important Warning
Do not test the transformer without a load connected. The WC50VA is not designed to withstand short circuits — testing without candles attached will void your warranty and damage the unit.
Result auto-applies to the quantity field below. You can always adjust manually.

SKU: WC50VA
- Powers up to 15 candles per unit
- Plugs into any standard 110VAC outlet
- 24V AC output — NEC Class 2 compliant
- UL Listed, suitable for damp locations
Select Your Wire
Use only WindowCandles WC18/2 proprietary yellow wire — any substitution voids your warranty.
Use Only WC18/2 Wire
Thermostat wire looks similar but is NOT compatible. Using any wire other than our WC18/2 yellow wire immediately voids your warranty and can cause system failure.
Daisy-Chain Layout
Wire runs daisy-chain from candle to candle along each zone. Plan up to 6 candles per run; keep runs under 400 ft to avoid voltage drop. Each box contains 500 ft.
Plan Your Zones
Organize by zone — Zone 1: first-floor front, Zone 2: first-floor rear, Zone 3: second-floor front, Zone 4: second-floor rear. Leave a 6–10" wire loop at each window for trim-out.
When In Doubt, Get Extra
Measure your total run lengths and add at least 20% for loops, overruns, and future needs. Unused wire can always be saved. Running short mid-install is a major headache.
We add a 20% buffer automatically. Each box = 500 ft. Result auto-fills the quantity below.
