Which is better Induction Highbays Or LED HighBays?
Both have their strengths and weakness. There has been much improvement in the efficiency of LED Highbays some reaching as much as 160lm/w compared to Induction 85lm/w So why would you choose Induction lighting over LED Lighting?
When LEDs are tested to be 100lm -160lm/w they are tested in a controlled environment usually on a bench top and the LEDs are tested before they are fixed on a PC board of which they will be installed, that all sound's good but once you put LEDs on a PC board with other LEDs it creates a lot of heat and loss of lumens, then you have the added lens, heat sinks, lamp shades etc that reduce the light output, so the actual lumens the fitting is producing is far less than 160lm/w. LEDs do not like heat so good quality LEDs that are producing 160lm/W need to have extremely good and efficient heat sinks, today there is no long-term study of an LED Highbay in a real field application running long hours and dealing with vast temperature changes in conditions, whether they will last as long as they are meant is yet to be seen, so for now, we are living in faith that they will reach the desired 50,000 hour life. Another drawback for LED high-bays, if because of overheating the LEDs fail you need to either replace this entire fitting or have a qualified electrician replace the LED PC board which drives the replacement cost right up which reduce the effectiveness of the energy savings which is why you changed to LEDs in the first place. Because LED is a very directional Light Often 120o for standard high-bays the quality of light is more like a powerful spotlight rather than an area light, so if you have to shelve you will often find a lack of light dispersing into shelving, This can be a problem to identify products or to see product prices for clients, see example of this at this linkhttps://www.atl-lighting.com/atl-induction-high-bay-lighting/low-ceiling-induction-lighting/atlqh-hf-series. Some LED high bays change the type of lens to give better light coverage but this reduces again the lumen output. Some types of high-bays the LEDs are mounted on a flat surface like a plate as seen in above link in order to produce a better spread of light but again as above link shows they don't produce good area light for shelving.
Induction High-bays have similar or better coverage than the standard HID, high-bays, the induction lamp produces a 360o light with the equal amount of lumens in all directions.Reflective light is often overlooked but excellent for even dispersal of light. In a warehouse or factory applications, these lights use objects to bounce light such as a ceiling, walls desks etc, this makes reflecting area light perfect for shelving and coverage of floor areas. Rather than have a complicated heat sensitive PC board with LEDS you have an induction bulb which handles heat excellently making induction lighting great for long hours in hot environments. What is good about induction lighting is it has been around for years and we have real field data so we don't have to rely on what a Laboratory says but real world experience. see
https://www.atl-lighting.com/warehouse-induction-lighting-video. Glare from LED lighting especially higher power highbays have caused problems with factory and office workers, see https://www.atl-lighting.com/warehouse-induction-lighting-video . Induction highbays have a proven record of long life up to 100,000 hours in real world conditions whereas to date they're no LED high-bays that have been running for 10-20 years. The initial purchase cost of induction highbays is cheaper as well making Induction High-bays economical. 50% energy savings+ Long life up to 100,000 hours + Excellent quality of Light + Cheaper purchase cost = the best ROI on the market for energy efficient high -bay lighting.

8 年Well, there is a lot of hard data on Induction lighting, Some years ago the US Department Of Energy published the results of Field tested induction lights over a 10 year period running 24 hours a day 7 days a week, after 100,000 hours 90% of the fittings were still operating. There is a number of field test from around the world on induction lighting. Also, in recent years, there has been further improvement in the efficiency both of the bulbs and ballast as well as new reflective technology to produce improved light output and distribution, and the improvements continue.Just wondering is there any Government or independent certified test that have been conducted on high powered LED fittings running 24 hours a day 7 days a week over 10 year period anywhere in the world?

8 年The biggest advantage of LED lighting fixtures are malleable and controllable. Along with energy efficiency. LED lighting has been rapid development in the past two years, as long as the product is good, it can reach L80> 80000 h. It can even exceed the long-term work at a high temperature of 60 degrees 50,000 hours. Also, due to the use of the lens, led light can be more precisely controlled, very evenly illuminated work surface, which is far much better than the shade, especially in the case of long-distance illumination. the induction lamp produces a 360o light, at a high temperature a bit better performance. But in the workshop lighting, table lighting situations, it is a lot of waste, may also have glare. High quality LED highbay, may represent a trend in lighting. However, there are still too many poor quality products in LED market.

8 年Mr.Alvyn Long has good analysis, but I am also agreed with Mr. GW Engelhardt , he has said the truth .

8 年Richard's numbers are just wrong. Phosphorous?? Alberto: i disagree that going to current-controlled, vs. PWM, reduces d4iver lifetime, becuase, in my experience, the worst part of the driver is the electrolytic cap's in the PFC stage, and the rest of the circuit, from a reliability perspective, is a wash....
