#LED #TBT

Our COO Ayn recently unearthed some photos from her childhood – a large part of which was spent in the offices of Light Waves Concept (the mostly-halogen predecessor to our current LED track lighting and cable kits). We couldn’t pass up this opportunity to share a couple of these throwback moments in New York City lighting history.

Here we see lighting specialist Charlie with specialist-in-training Ayn.

“hey charlie? don’t you think these lights could one day be, i dunno, longer lasting and energy efficient?”

The LED Waves showroom looks very different now, as we’ve hopped over to Brooklyn and shifted focus away from the decorative lighting market. But we like that, despite being decorative, that red downlight fixture from the ’80s bears a resemblance to a modern, industrial downlight: the Andromeda LED high bay.

Another similarity can be found in this action shot of Teddy (RIP old boy) strolling through the Light Waves Concept office, alongside Willow, who now resides over LED Waves.

Willow, right, models an LED T8 tube, while Teddy models his boss self.

While our love of dogs remains the same, our passion for lighting has grown as LED technology emerged and continues to change the game, improving our quality of life – and quality of light – beyond baby Ayn’s wildest dreams.

Double Waves of Savings: LED PAR20 and PAR30 Light Bulbs on Sale

Our first Waves of Savings promotion of February brings you a two-week sale on two LED lights made in the USA exclusively by LED Waves. Today through Tuesday, February 18 2014; coupon code WAVES saves you 15% on the Dallas™ Dimmable LED PAR20 and the Chicago™ Dimmable LED PAR30.

Waves of Savings.LED PAR20 PAR30 saleThe Dallas LED PAR20 and the Chicago LED PAR30 are 9 Watt replacements for 75 Watt halogen lamps. The quality of light from both bulbs is virtually identical, due to the same high end components and craftsmanship that go into each one. Both offer:

  • American-made quality – assured by our 5 year warranty
  • 7-array of Cree XLamp  XT-E LEDs
  • Heat sink finely machined with aircraft-quality aluminum
  • Plug & Play; Compatible with standard incandescent/halogen sockets & dimmers

What separates these PAR lamps is their size. The number after PAR, multiplied by 1/8 of an inch, equals the diameter of the light head. So LED PAR20s are 2.5 inches in diameter, while LED PAR30s are 3.75 inches in diameter.

Our in-house R&D and production team makes LED light bulbs for almost every track light system, ceiling recessed can, and other flood or spotlight applications. For help finding what you need, give us a call at 1(800)986-0169.

LED Wall Packs Ahead of Lighting Standards

Some individuals interested in the Owl Outdoor LED Wall Pack family have asked us if any of the units are qualified by Energy Star or the DesignLights Consortium. (Energy Star applies to green products typically for the home and for retail and hospitality settings, while the DLC covers the remaining larger, more industrial lighting projects.) It is with heavy hearts that we answer no, simply because these programs currently do not offer a category for outdoor bracket-mounted wall packs.

Why is this the case? Traditional wall packs using metal halide, HID or sodium vapor were associated with lots of uplight – which is wasteful, creates light pollution, and can contribute to unsafe nighttime lighting conditions.

The directionality of solid state technology makes our own LED wall packs emit NO uplight. Check out all the zeroes across the board in the “U” (for Uplight) section of the B.U.G. reports for the 10, 30, 50, 70, 100 and 200 Watt Owl Packs. Each also meets the DLC’s high end specifications for related outdoor LED lighting categories – measuring brightness, efficiency, color rendering and more:

Owl Outdoor LED Wall Pack vs. DLCUntil Energy Star or the DLC recognize LED wall packs as viable nighttime floodlighting, it’s up to local utilities and building contracts with Buy American provisions to offer incentives for the high performance and energy savings of the USA-made Owl Pack. The technology is there already; we’re just waiting for the “green light” from the rest of the green lighting community.

A More Halogen-Like Dimmable LED Light Bulb?

A recent LEDs Magazine story uncovered some new design processes for dimmable halogen replacement bulbs. These processes require a lot of refinement (and solutions to new problems), with the end-goal of making LED bulbs appear to dim the same way as halogen/incandescent bulbs.

We emphasize appear, because the two lighting technologies handle dimming very differently. A halogen dimmer changes the amount of current running through the bulb. When you lower the current, filament burns less intensely. In addition to dimming the light (reducing its output), this also changes the light color to a warmer Kelvin temperature.

The phosphor layer on a lighting class LED changes its natural blue light into a different color. Though phosphors can be mixed to create pretty much any color temperature, by nature they inhibit some of the light output.

Increasing the density of materials in an LED package (as in the diagram above) also raises the operating temperature, which overworks the electronics. Therefore, an LED designed to replicate halogen dimming must have a dedicated thermal management solution, and may come with an overall energy efficiency trade-off.

In all the years LED Waves has manufactured and sold dimmable LED light bulbs and systems, we’ve always considered their consistent light quality as an improvement on halogen technology. No customer has ever approached us asking for a bulb that changes color temperature when it dims.

We’re always open to new technology, however, so this conversation intrigues us. What do you think? Would you sacrifice energy efficiency or lifespan for more halogen-like dimming? How else might an LED bulb better replicate traditional lighting technology?

LEDs, BUGs, and the Fight Against Stranger Danger

When browsing literature to specify lighting, you may come across something called a BUG rating. (These are part of the Outdoor Photometric Test Reports like the ones for each Owl Outdoor LED Wall Pack.) This three-number score does not assess whether your lights brings all the bugs to the yard – though LEDs, with their particular UV-free spectrum, do cut down on insect visitors. Instead, this rating measures Backlight, Uplight, and Glare.

backlight-uplight-forward.lightAs these are all undesirable features, the BUG scale is one in which you actually want low scores. By nature, our wall-mounted LED floods reduce backwards and upwards light waste due to their directionality. This explains the low numbers for the B-U portion of the Owl Pack’s BUG ratings – these figures are more important for free standing street lights, as illustrated at right.

The G portion is a bigger challenge for LEDs as well as any other outdoor lighting technology. Glare distorts the way the human eye naturally compensates for the darkness around a light source. This diptych illustrates the stranger danger posed by high glare lighting from an outdoor HID lamp.

the importance of low glare outdoor lighting

Low glare is important for improving nighttime safety, and why we took such care in the Owl Pack’s fixture design. Our G score is 0 for all the residential units, and 1 for the higher-powered industrial flood lights.

When sourcing any outdoor light, read the product’s Photometric Outdoor Test Report and BUG score to make sure it meets the safety requirements of your application. With impressive specs across the entire line of Owl Outdoor LED Wall Packs, we highly recommend these floods to make your building exteriors safe at night.

Who’s Who in the Owl Outdoor LED Wall Pack: Heat Edition

Today’s “Who’s Who” is the hottest one yet, as we focus on the two-tiered thermal management system for the Owl Outdoor LED Wall Pack series. From the 10W Owl baby (the Owlet?) to the industrial 200W version, we took special considerations to minimize heat inside each unit. That’s because high operating temperatures creates more stress on the components, which can lead to premature failure in any electronic device.

WhosWho Owl Pack thermal management

On the back of the Owl Pack you may notice a heat sink similar in form and function to the ones on our other American-made LED lights, like the Andromeda high bay or our PAR light bulbs. These heat sinks are composed of many rows of aluminum blades, each finely machined to maximize surface area. It is this increased surface upon which hot air dissipates outwards & away from the electronics inside. (See Fig. 1, below.)

Hidden underneath this is an added defense, exclusive to the Owl Pack Outdoor series: a pair of copper pipes that connect the heat sink to the internal electronics. The liquid core of these highly conductive pipes offers superior thermal transfer rates over any other metal. (Fig. 2, below.)

Owl Outdoor LED Wall Pack Thermal Managment System

Though these raw materials are expensive, the lightweight, malleable qualities of aluminum and copper significantly lower costs for our production team. As a manufacturer AND a supplier, LED Waves is then able to transfer these savings directly onto you!

Now Available: 50W Owl Outdoor LED Wall Pack Test Results

LED Waves is pleased to announce the release of the UL Photometric Outdoor Test Report and IES files for the 50 Watt Owl Pack! These results are the first of many that will come in for this 10-200 Watt series of outdoor LED wall packs.

This is an exciting development, not just for those looking to specify this particular LED flood light for a home or business, but also for LED Waves’ R&D team. This the first report of its kind that we have gotten (as the Owl Packs are the first outdoor units from our line of exclusive LED lights made in the USA) and our expectations – based on the specs for the Bridgelux Vero-18 and LED driver we built in – were far surpassed in the UL test results.

At 4,581 lumens, the 50 Watt Owl Outdoor LED Wall Pack tested over 12% brighter, with 346 more initial lumens than we had projected. And our BUG rating (which measures Backlighting, Uplighting, and Glare) came out to B2-U0-G0, proving this flood suitable for minimizing light pollution and improving outdoor light quality.
