LED review: best 100 watt alternative from EternaLEDS
The Quanta PAR38 LED from Eternaleds runs off just 18 watts of mains electricity, and outputs light equivalent to a 100 watt incandescent light bulb. The quanta PAR38 is a simple screw in retrofit unit that will easily replace your conventional E27 floodlight or spotlight bulbs. When you do so, you can sit back and forget replacing it again for the next 35,000 hours or about 12 years normal use*. All the while you run this LED, you can also be assured that you are getting the maximum light output for the minimum electrical usage. The Quanta PAR38 is definitely one of the best designs in today’s current LED lighting products.
The Quanta PAR38 is a well designed and attractive unit that will complement any style or décor. It has an integral transformer that allows it to take 110-220V allowing it to run in any country. For lower power there is also a 9 watt version and both come in 2 variants outputting daylight white and a genuine warm white, that during our tests appeared one of closest colour matches for incandescent I’ve seen to date. Unlike the CFL, these lights won’t flicker, buzz, grow dull in cold temperatures. They start instantly with no warm up. We note they are also ROHS compliant and thus environmentally safe. In addition, their life expectancy is rated until the unit drops to 70% of light output, not until total failure!
The 18 and 9 watt versions have a patented air cooling shatter-proof plastic structure that supports the LED units mounted in the front end of the assembly. This grid design provides adequate ventilation for the minimal heat dissipation required by the LEDs. Don’t worry though, you can easily touch any part of the light even after it’s been running for several minutes. Unlike a conventional bulb, LEDs convert 80% of electrical energy into light and only 10% into heat.
The real questions we all want to know is what does the light look like? Is it as good or better than my old bulbs? Well, you have to buy one to see the real thing, but we’ve taken some video of a quanta 18 floodlight in a typical room environment. See the video here. Video and stills are not ideal in artificial light, but you’ll get the idea and hopefully see that this is a real grown up LED that delivers power and quality to match any conventional bulb. We feel the light quality is much superior to a CFL of similar output and of course excels in the other aspects of energy saving and long life spans.
The Quanta is more than just a light bulb. It’s a complete floodlight assembly that looks good and performs effortlessly.
THE NOT SO GOOD
There are still issues with LED lighting that may trouble some users. Colour quality has been a big problem for many LED lights with poor colour rendering index (CRI) and limited dispersion of light. The Quanta scores well for colour quality. However, because LEDs produce a very intense light, we still see heavy shadowing when the light beam is interrupted. This is because the 6 light modules in the Quanta 18 have minimal diffusers to scatter the light and thus maximise reflective dispersion from around the surrounding surfaces. As a flood light the Quanta 18 works very well, offering a good throw and spill of light in soft coned area in front of it. The Quanta 18 can not be used with conventional dimmers, although my guess is that a PWM dimmer circuit will work (not tested). We also speculate that the air cooling framework may yet prove to be a harbour for airborne dust, which will become unsightly and should be cleaned anyway to maintain good ventilation. One little quirk you need to get used to is turning them off: Because they use so little power, there is a slight delay of about half a second as the inbuilt regulator offloads.
We should not see the Quanta range as replacements for single omnidirectional room lights. In our video you will see poorly lit areas around the room that are not reached by the direct beam of light. In architecture and target lighting, however, this isolation pattern would be a bonus. To be clear, this LED is intended as a directional floodlight and by itself is not suitable for omnidirectional space lighting as you would expect a conventional incandescent of CFL. Used in groups, or as down lighters provides a more balanced dispersion as can be seen from these images.
many people see LEDs as far too expensive in comparison to conventional bulbs. What you have to realise is that a well designed LED lasts up to 17.5 times longer and uses up to 10 times less power for the same light output. When you do the sums, you see that investing in a LED unit is much cheaper in the long run, when you compare the replacements or conventional lighting and electricity costs. It also means LEDs are especially suited for poor accessibility locations, as you can simply fit and forget.
The Quanta PAR38 is an attractive well designed LED product that offers superb performance and economy. In addition, it ticks all the right boxes for ecological and environmentally friendly lighting. In a later review, we’ll show you the smaller versions of the Quanta PAR30 9 watt and demonstrate a simple little trick to overcome the shadowing effect and turn a single floodlight into a full room light with soft, even light dispersion. These are most versatile units and we give them a no reservations thumbs up!
