## Overview

The J.LUMI YCA1008 Twist Lock Photocell Sensor is a UL-listed, next-generation electronic sensor designed for seamless dusk-to-dawn control of outdoor lighting. Compatible with a wide range of fixtures including LED and induction lights, it features a fast-reacting, drift-free circuit board and a smart 5-second delay to prevent false triggers. Easy to install with standard NEMA twist lock receptacles, it supports up to 1000W load, making it ideal for commercial and residential outdoor lighting solutions.

## Description

J.LUMI YCA1008 is the next generation twist lock photocell sensor. Instead of using dated thermal mechanism, our photocell sensor features next generation electronic circuit board. It is ideal for 208-277 VAC light fixtures with ANSI C136.10 NEMA turn lock receptacles commonly found on dusk to dawn type barn or post lights. It provides dusk-to-dawn lighting control and saving energy when controlling exterior lighting, street and parking lot lighting. Built-in delay eliminates the load temporarily switching off due to car headlights, lightning or another temporary light source. Turn lock design using industry standard prong plugs makes this sensor easy to remove and install if replacement is needed.

## Features

- | UL LISTED | UL listed to qualify for all types of residential and commercial applications such as outdoor area lights, parking lot shoe box lights, street lights, etc.
- | NEXT GENERATION | Unlike outdated thermal photocells (with a bi-metal looking through the window), our product uses next generation electronic circuit board with repeatable set point that does not drift during product lifetime. It has much faster reaction time and works better with LED and induction light fixtures due to their ability to withstand high inrush current.
- | EASY TO INSTALL | Compatible with standard twist lock receptacle (not included with this product). Easy to remove and install. Perfect for replacing your old twist lock photocell.
- | ERROR PROOF | Works with standard NEMA turn lock receptacles commonly found on dusk to dawn type barn or post lights. A built-in 5-second time delay feature avoids false triggers such as car headlights or lightening.
- | ELECTRIC SPECS | AC 120V 60Hz, 208-277V 50 Hz, 1000W Tungsten, 1800VA Ballast; incandescent, fluorescent, LED, halogen, mercury vapor, high pressure sodium, and CFL compatible. User manual is available for download at the lower right of this page.

## Questions & Answers

**Q: how do you adjust it to point north**
A: The north orientation was determined by the receptacle base (not included in our light).  This is a replacement photocell. To install the unit, match the larger prong of the 3 with the large inlet on the receptacle base. Push the photocell into the receptacle to make sure the contact is tight, then twist turn the photocell clock wise to lock the photocell in place.  The sensor window should be automatically pointed north, assuming the receptacle was installed properly and facing north too.

**Q: If i install this onto my existing fixture which uses an incandescent bulb will i be able to change the light bulb to led?**
A: If the LED bulb screws into the existing fixture, I see no reason why I shouldn't work.  As I understand it, the photocell merely allows electricity to flow to the bulb when it activates.

**Q: Will this work as a replacement for a Fisher Pierce 6660N photocontroller?**
A: I don't know the Fisher Pierce off hand but I can tell you if you have the three prong / rotational turn design it will work. This attachment connector is standard for the industry.

**Q: You have it listed as 1000w tungsten, 1800va ballast, is that supposed to read 1800w tungsten, 1000va ballast? that is what mine states. thanks.**
A: It is a photo cell switch that closes at dark and opens at daylight. I don't know what my ballast was rated for but if it states that on amazon then it is correct. I am very happy with the product and works as I thought it would.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works at the subdivision entrance lights
*by T***2 on May 7, 2025*

I help maintain the entrance to our subdivision (lights, sprinklers, timers, etc.) About 5 yrs ago, I replaced the light sensor / contactor with this part. Worked flawlessly for 5 yrs so pulled up my old order and got another one when the light-on operation got a bit sketchy. Couple nights we had NO entrance lighting. In fairness, we have had a LOT of power outages and the voltage spikes that go along with that (I lost a modem and a desktop during the crazy power fluctuations during Hurricane Helene). First one lasted 5 yrs under that abuse. I am sure this one will be as reliable!

### ⭐⭐⭐⭐⭐ Works Great!
*by V***L on January 8, 2025*

Works Great!

### ⭐⭐⭐⭐⭐ Exactly what I needed
*by M***A on October 29, 2024*

Replaced the old sensor in my yard light. Still working great 2 years later.
