Designed for art galleries, museums and retailers, SPEQ is a modern-styled, highly efficient LED solution that delivers lighting on target with outstanding color quality and performance. With its 90+ CRI and full gamut LED chip, SPEQ produces crisp whites that make all the other colors seemingly jump. Its beam spreads—from narrow spot to wide flood—perform well from a few feet away to as much as 40 feet away. The product ships in 10 days.
The platform delivers an improvement in collision safety through the use of a multiload path structure, Hot Stamping, and super-high-tensile steel plate. The sophisticated multiload path structure increases the energy that the vehicle absorbs in collisions.
That’s true of mature products, but the LED ‘bulb replacement’ market isn’t quite there yet. As a relatively new product, responsible companies are still seeing how they can make them efficiently (cheaper!) and still be decent, while competing with ‘overseas’ manufacturers who, in some cases, don’t really care about quality as long as they can finagle shelf space in the stores. Since the cost of processing returns for fails is more than they cost the store to buy in the first place, they don’t stay on the shelves for long. Once the unreliable brands are done being weeded out, the low end of the curve should lift up a bit.
The building—which was New York City’s first YMCA and housed such luminaries as Fernand Léger and William S. Burroughs—was where Rothko painted his famous Seagram murals
The Actik is powered by a “hybrid concept”, which means you can either use three standard AAA batteries or Petzl’s high capacity CORE rechargeable battery. That would be fine, if it weren’t for the fact that you have to buy the rechargeable Petzl Core battery separately (£23.10 at Amazon).
In general a high CRI (>90) is going to be almost indistinguishable from an incandescent. One in the 80s will generally look fine and probably won’t be noticeable, but may occasionally emphasize or de-emphasize certain colours. Below that is where the badness of the light starts to become obvious.
If you take the case in general, take the average room. Or let’s just take my room for an example. I have various lamps around the room that collectively equal about 200 Watts worth of standard bulbs – but they’re all spot lights that illuminate a desk or an area of the floor. Then there’s one 73 Watt halogen bulb hanging off the ceiling. Turn all the spotlights on, and the room still looks like it’s dimmed down. Turn the spotlights off and the ceiling light on – the room looks bright. For general lighting, directional lights aren’t more efficient because you actually don’t want to throw the light at the floor – you want to throw it everywhere around in order to provide diffuse ambient light that lights up the whole space.
Light bulbs have an enormous, everyday impact on the way our homes look and feel, and with a flood of new LED bulbs filling the lighting aisle, you've got more options than ever. But how do you pick the right lights for the job? The trick is to think about how you typically put light to use in the different rooms in your home. That, more than anything, will dictate your lighting needs.
Improved light levels and uniformities, for public safety; improved visibility with glare reduction; substantive energy savings; top notch quality; and little to no maintenance.
What I will say, though, is that you may need to stick to the same model of bulb if you want consistent dimming. Often if you switch to a different brand or model, you’ll either have a minimum that’s quite bright, or not have any light until the knob is at 50%
With regards to the emergency luminaires we had to achieve a minimum light level of 15 lux, however due to the large spacing between each TOTEM it quickly became apparent that the original design, using high level luminaires around the perimeter of the TOTEM, was not going to achieve the target performance. Our design team endeavoured to achieve the goal, however once we had proven the design would not work, we worked on a solution that would provide the light levels required and go on to be approved by Crossrail’s Design team. Our solution meant we preserved 2No horizontal luminaires at high level on the 2No long sides, omitted the short horizontal luminaires and replaced these with 1No high level long vertical and 1No low level short vertical luminaire on each side.
