The emergency ballast consists of a high-temperature nickel cadmium battery, charger and electronic circuitry in one compact white case. The BAL 500 can be used with one 17 W through 40 W (2' - 4') T8, T10, or T12 fluorescent lamp without integral starters, including U-shaped, HO, VHO, circline, energy saving, and (4-pin) long compact. It is also compatible with most 1, 2, 3, and 4-lamp electronic, standard, energy saving, and dimming AC ballasts. If used in an emergency-only fixture, no AC ballast is necessary. This ballast is not suitable for use in air handling heated air outlet fixtures, and wet or hazardous location fixtures. ## Features - Provides a minimum of minimum of 90 minutes of emergency illumination - Can be installed inside, on top or in remote of fixture - Can be used in both switched and unswitched fixtures - UL924 Listed for damp location - UL Listed for Retrofit/Field installation ## Technical Specifications | Specification | Value | |---------------|-------| | Accepted Voltage Frequency | 100 to 240 Volts and 50 Hertz to 60 Hertz | | Additional Features | Energy Efficient | | Asin | B00JJ1R8WY | | Best Sellers Rank | #411,272 in Tools & Home Improvement (See Top 100 in Tools & Home Improvement) #294 in Electrical Ballasts | | Brand Name | Best Lighting | | Bulb Base | G13 | | Bulb Shape Size | T8 | | Color Temperature | 2700 Kelvin | | Control Method | Remote | | Controller Type | Remote control | | Customer Reviews | 5.0 5.0 out of 5 stars (8) 5.0 out of 5 stars | | Efficiency | Energy Efficient | | Indoor Outdoor Usage | Indoor | | Is Electric | No | | Item Weight | 0.01 Ounces | | Light Color | warm white | | Light Source Operating Life | 25000 Hours | | Light Source Type | Fluorescent | | Light Source Wattage | 40 Watts | | Light Type | Fluorescent | | Manufacturer | Best Lighting | | Manufacturer Part Number | BAL500 | | Material Type | nickel | | Model Name | BAL500 | | Model Number | BAL500 | | Number Of Items | 1 | | Package Quantity | 1 | | Power Source | Battery Powered | | Shape | Tubular(T) | | Specification Met | UL | | Unit Count | 1 Count | | Upc | 842923103259 | | Voltage | 2.77 Volts | | Wattage | 17 watts | | White Brightness | 450 Lumens | ## Product Details - **Brand:** Best Lighting - **Bulb Shape Size:** T8 - **Light Type:** Fluorescent - **Special Feature:** Energy Efficient - **Wattage:** 40 watts ## Images ![Best BAL500 350 to 450 Lumens 120/277v Fluorescent Emergency Ballast - Image 1](https://m.media-amazon.com/images/I/51LT+EAI7UL.jpg) ![Best BAL500 350 to 450 Lumens 120/277v Fluorescent Emergency Ballast - Image 2](https://m.media-amazon.com/images/I/21gxRAegIPL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/24899738-best-bal500-350-to-450-lumens-120-277v-fluorescent-emergency](https://www.desertcart.us/products/24899738-best-bal500-350-to-450-lumens-120-277v-fluorescent-emergency) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-06*
