The Distributed Array boards consist of multiple low-power LEDs in a precise layout that enables thermal self-management, delivers high efficacy at all CCTs and eliminates the need for supplemental heat sinking. The 9 long Distributed Array boards consume about 11 watts of power or less, while the 11 boards consume 9* watts or less. The 18 board consumes 22 watts. The boards produce an even and diffuse light that reduces the need for multiple optical layers, simplifying the luminaire design and maximizing optical efficiency. The Distributed Array products are a long-life, energy-efficient alternative to linear fluorescent sources. The Distributed Array LED Modules are designed for optimum performance when paired with OPTOTRONIC constant current power supplies for maximum system efficiency and life expectancy. Review: worked but poorly packaged - 10 Power supplies were received in working order and as described however the power supplies were shipped LOOSE in the box and had cosmetic damage as well as bent mounting ears. For $500 you would expect desertcart to pack a shipment of electronics in bubble wrap. ## Features - 50 Watt, Bi-level StepDIM power line - Dimmable, Constant Current LED Power Supply - Boards incorporate multiple LEDs driven at low-current - Ideal replacement for linear fluorescent sources - High efficacy ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00V4UYJIE | | Best Sellers Rank | #204,597 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #8,025 in LED Bulbs | | Brand | LEDVANCE | | Brand Name | LEDVANCE | | Customer Reviews | 4.3 out of 5 stars 4 Reviews | | Global Trade Identification Number | 00046135793776 | | Included Components | 1 Power Supply | | Item Type Name | LED power supply | | Item Weight | 8.11 ounces | | Manufacturer | LEDVANCE | | Maximum Frequency | 60 Hz | | Model | 79377 | | Mounting Type | Cable Mount | | Part Number | 79377 | | Power Source | Ac Mains | | Specification Met | CE | | UPC | 046135793776 | | Unit Count | 1 Count | | Warranty Description | 5 year limited warranty | ## Product Details - **Brand:** OSRAM - **Power Source:** Ac Mains - **Mounting Type:** Cable Mount - **Maximum Frequency:** 6E+1 Hz - **Specification Met:** CE ## Images ![OSRAM OPTOTRONIC 50W Constant Current Step-Dimmable LED Power Supply, 1 Pack, White - Image 1](https://m.media-amazon.com/images/I/61iOUMWXzlL.jpg) ## Questions & Answers **Q: will these dimmable ballast work and feed 2 LED U-lamps** A: Thanks for the question. This particular driver won't operate LED tubes. You might want to contact lightbulb@ledvance.com and they can provide you with a list of compatible ballasts/drivers for a LEDVANCE Sylvania LED tube. If it is a competitors tube, they should also have a compatible list of ballasts/drivers they have tested. **Q: Is this a replacement for the ot180w/unv/800c/2dim/p6 ?** A: It could be. Depends. Did your original driver come out of a fixture? If so, we don't know what mA it was programmed for. If you know, and have a programming tool and the software, you are good. Otherwise, you might want to contact the fixture manufacturer for a properly programmed replacement. ## Customer Reviews ### ⭐⭐⭐ worked but poorly packaged *by B***E on November 22, 2023* 10 Power supplies were received in working order and as described however the power supplies were shipped LOOSE in the box and had cosmetic damage as well as bent mounting ears.
