POWERBAY | Specifier Series

PowerBay delivers unparalleled power and performance

HE Power Performance Options

PowerBay scales to deliver the performance you need based on four sizes, with up to 12 individual LED arrays at up to 270 - 540W and 40 - 89,000lm. This provides lighting designers with the ability to set specific luminaire in specific locations whilst maintaining the same aesthetic and common components for long term maintenance.

Built to survive harsh conditions

It’s true. Size matters.

Adaptive Optics

PowerBay features rotational arrays, with optional reflectors packs, that snap between heatsinks. Providing additional flexibility during installation to optimise uniformity. 

Unsurpassed uniformity on vertical and horizontal surfaces

PowerBay’s adaptive optics, eliminate pooling and shadowing on floors or at the top of high stack warehousing. It delivers unsurpassed levels of uniformity on both horizontal and vertical surfaces. 

PowerBay eliminates pooling or vignetting to provide high levels of visual acuity around complex machinery or to the faces of high stack storage.

Ra95 for colour critical applications.

Available in four standard colour temperatures, from 2,700~6,000ºK with superb colour rendering at both Ra85 and Ra95.

Powerbay PB8-HE-495-360W (IES LM79 TM30-18)
≥138lm/W @ Nominal Ra95 / 4,000k (CRI 94.2)

Ra85 boosts efficacy

Specifying Ra85 increases lumen output whilst maintaining full colour rendering, high R9 with neutral bias, perfect for general industrial commercial and retail applications.

Powerbay PB8-HE-485-100W-DA (IES TM30-18)
≥150lm/W @ Nominal Ra85 / 4,000k (CRI 85.9)

Ambrite™

Ambrite™ is a new LED chipset from Isollux that effectively eliminates blue spectrum below 500nm. Ambrite™ chipsets deliver up to 129lm/W, outperforming products that rely on filters or optics to control blue peak emissions.  Ambrite is perfect for photosensitive manufacturing, pharmaceuticals, brewing and exterior applications where insects present a significant commercial risk, such as loading bays. To order, simply specify AMB in place of Ra/CCT.

Isollux Ambrite™ LED offers two distinct environmental colour tones for photo-sensitive applications such as high performance 3D printing, photo-lithography and pharmaceuticals. Both options eliminate wavelengths below 500nm with only moderate differences in spectral performance. 

Customers can choose the most appropriate colour for staff by specifying either Ambrite™ AMX (Pictured above) or the warmer Ambrite™ AMH (below). 

Soffito SLP is easily customised to provide dual chip options to a single luminaire, making total control of the lighting environment available at the flick of a switch, ideal for dark rooms or small laboratories.

How and why we de-stress key components to achieve maximum service life and optimum value

Isollux HE Chipsets are backed by independent photometry reports including, LM79 for colour rendering and IES files; and LM80 (10,000Hrs) predictive endurance tests. The LM80 reports allow engineers to accurately predict the expected performance of individual LEDs across a given range of thermal and electrical conditions. Typically manufacturers use this data to run the LEDs in circuit at or near peak loads to minimise cost to market by reducing component count.

Our engineers use the test data, as a bench mark from which to de-rate components, increasing the number of LED in circuit to optimise performance. Increasing LED count allows us to reducing drive current lowering the thermal load on all critical components, including the LED die, driver, PCB and electrical connections. This approach delivers significant gains in, efficiency, performance and reliability, in particular maximising the service life of each of the key components. 

Powerbay-HE Drive Current | ƒ

The illustration below scales the maximum allowable forward current for the Isollux HE chipset and the drive current used in the independent LM80 reports compared to the actual drive current used to power Powerbay (288 LED HE High Density Array per bar i.e Powerbay 8 @ 288 x 8 - 2304).

Powerbay-HE Case temperature TC

The illustration below scales the case temperatures used in the LM80 reports tested at 150mA, compared to the actual case temperature of production models driven at 50mA. The combination of reduced If and Tc significantly increases performance and reliability.

Customer benefits of de-rating components

De-rating components reduces the Total Cost of Ownership (TCO) ie it reduces the long term cost of both operating and maintaining a lighting solution. Rather than focusing on headline price. TCO includes the capital cost of the luminaire and the cost of installing and maintaining the fixture.

The cost related to regular replacement of LED fittings is often overlooked. In the case of clean rooms it also generally results in significant business interruption to complex and sensitive production facilities. Adding the additional risk of performance caveats such as B’ratings and the costs quickly spiral. (See illustration below)

Isollux products are designed to surpass warranty without caveats, even when installed in challenging environments at high ambient temperatures. It provides specifiers with the option to compare operational savings over extended periods. Up to 200,000 Hours L70 when using lighting controls or a lower light loss factor, with the option to increase driver output retrospectively at the mid point in the product life cycle where controls are not an option.
