These extension cables makes it possible to daisy chain multiple
under canopy lights. Please see our FAQ below for further information on
power cord and extension cable needs for daisy chaining multiple benches.
- 3’ cord
- Links together two lights that don’t directly connect into each other. Primarily used to connect two adjacent rows of lights on a bench.
How many lights do I need?
Convert your bench length to inches, then divide by 46". That is how many lights each row can support.
Example:
14' bench length, 3 plants wide
14' x 12" = 168", 168" ÷ 46" = 3 lights (round down)
3 x 2 (available rows in-between plants) = 6 lights
How many power cords and extensions cards do I need?
Each bench requires at least one power cord. Depending on your total lights, you can daisy chain your rows with an extension. If you exceed max daisy-chain #, you will need two or more power cords per bench.
Max Daisy-Chain #
1.0 Amps - 10 lights - 120v
0.5 Amps - 17 lights - 240v
0.43 Amps - 20 lights -277v
Examples -
Scenario 1
240v, 6 lights per row, 2 rows of lights, 12 lights total = One 240v power cord and one extension cord per bench
Scenario 2
240v, 12 lights per row, 2 rows of lights, 24 total = Two 240v power cords per bench
Scenario 3
240v, 8 lights per row, 3 rows of lights, 24 total = Two 240v power cords and one extension per bench
