The proud work of the Chinese boutique strategy — The evaluation of Meizu Lipro spotlights

I was very honored to get the spotlights of Lipro at the first time. In the evaluation of the first few times, I gained many surprises and felt the care of the Development team of Lipro from the products. When I opened the spotlights package, I had an intuition that this lamp would be successful and it solved the problem of too many traditional spotlights.

This article will analyze this spotlight from engineering design, light source quality, practical effect and other aspects, big surprise in the practical effect.

1. Engineering design

Lipro spotlights in the installation, convenient use, debugging and other aspects, compared with the traditional spotlights have a qualitative leap.

Appearance design

Unique appearance design, integrated lamp body, square and square rank, fine sand surface ring processing, narrow edge design is more concise, the outer diameter of the lamp body 86mm, it is recommended to open 75mm, the height of the whole lamp is 7.5cm, the height of the layer is not high, more practical space.

Note: 70mm aperture can not be installed, 80mm can be installed.

14 fins radiator in the guarantee of beautiful at the same time, greatly increase the heat dissipation area, reduce the working temperature of the light source, alleviate light failure, room temperature of 30℃, lit one hour after the measured temperature of the radiator is 56.3℃.

Riveted clamp spring design

People who often contact spotlights know that the conventional spotlights clamp spring:

This spring has certain disadvantages:

?). When installing the lamp, the spring is scraped off without paying attention to it. It is difficult for inexperienced people to reinstall it.

?). In the removal of spotlights, it is easy to be injured by the powerful spring, especially the kind of pain played to the nail, to the heart.

Lipro spotlight is the design of riveting + spring, solve the problem of spring drop and accidental injury.

Angular reference line

The lamp body supports unilateral 25° Angle adjustment and has Angle reference line, which greatly improves the efficiency of multi-lamp Angle adjustment.

The lamp body can be rotated

Conventional spotlights in the installation, to pay special attention to the direction of adjustment, such as the error is slightly large, it is necessary to take down the whole lamp and re check the direction, Lipro lamp rotation design, lamp installed no longer need to consider the direction of adjustment, just a gentle turn, you can meet the adjustment of any direction, that is so simple.

Quick installation design of drive power supply

Bid farewell to the traditional electrical tape, but also to avoid the electrical tape years off the hidden danger, just gently press, you can firmly stuck cable, test with 0.75 flat soft line can be stuck, the conventional household 1.5 flat lamp line will be more stable, to like to do their own little friends are very friendly.

I don’t know the circuit design of power supply, so I’m not qualified to comment too much, but AT least I can recognize what the isolated power supply is. I used the X brand spotlight that I got at Ybao at ￥59 to disassemble the power supply and make a comparison. I believe everyone has a steelyard in their heart.

Custom honeycomb anti-dazzle

More intimate is, with the lamp with the honeycomb anti-dazzle net, detachable lamp cup design, according to the actual situation, can decide whether to add the honeycomb anti-dazzle net to enhance the ability of anti-dazzle, super awesome.

Since cellular networks are so effective at reducing glare, why don’t they come as a standard instead of a DIY accessory? We’ll talk later.

The front part is IP54 protection grade, which can be used in kitchen and toilet. Die-cast aluminum lamp body and riveted clip spring are stainless steel to avoid corrosion in wet environment.

The process treatment is shown in the above pictures, which are all real pictures without any processing. The joints, face rings and internal components have been processed in place, and no obvious defects have been found.

Summary of engineering design:

Developers are really standing in the user’s perspective to think, as far as humanization, convenience, personalized.

2, light source quality

The test model is liPRO8W-36 °-4000K standard, through the ceiling lamp, foot lamp, cabinet lamp test, has basically estimated the spectral model, the whole system is “full spectrum” light source.

spectrum

Lipro spotlight 4000K spectrum

The comparison of 4000K for a Ra95 lamp is more intuitive.

A brand Ra95 luminaire 4000K

Lipro has better spectral continuity, a fuller spectrum and a lower peak high-energy blue light crest.

Color rendering index

Ra=98, R1-R15 starting value 94, almost meets the excellent level of painting requirements.

The measurement will be slightly off

Color temperature/color tolerance

The labeled color temperature is 4000K, and the measured color tolerance is only 2.7SDCM, which is better than the ceiling lamp with the same light source. Since the spot lamp is a key lighting fixture, the design team should have made a lot of optimization to minimize the color deviation problem, which is relatively excellent.

Rf-Rg

Color saturation and color fidelity approach 100, excellent.

Illuminance and region

The test is 36°, the official standard is 500lm luminous flux, the vertical height of the lamp distance from the probe is 200cm, close to the distance from the conventional commercial housing ceiling to the working surface.

The measured illuminance is 308lx, if it is a single lamp for the top of the coffee table is not enough, 200cm distance obvious spot size is about 170cm, with a larger irradiation area, is the case to choose 24° or 36°, the same distance 24° spotlight illuminance should be above 450lx (pure guess).

After the addition of the cellular network, the light in the area was more uniform due to the grid’s segmentation of light, which dropped from 308lx to 267lx, which is probably one of the reasons the design team chose the cellular network as a DIY accessory.

3, the actual use effect

Scope of glare

Tips: It is quite subjective, because it is to look directly at the light source actively, the situation is quite extreme, just for reference.

Test conditions: the height of the conventional commercial house is 275cm, the height of the ordinary sitting line of sight is about 130cm, and the light source is directly looked at in the normal sitting position.

Do not install cellular anti-glare nets:

The distance between the lamp and the person sitting in A normal position is about 190cm and the glare starts to be felt. A→C gradually increases, and it is unacceptable to look up at the lamp in C→D area.

After installing the cellular anti-dazzle net:

About 150cm away from the lamp, glare began to be felt, and gradually intensified from B to C. In C to D area, the glare was unacceptable, and the intensity was lower than that of the non-cellular grid.

In the application scene of home lighting, the anti-glare performance of traditional spotlights has been greatly improved after the addition of cellular grid and the illumination is given at an Angle of 30+ from the wall.

The anti-dazzle distance of the standing posture is much better, and the anti-dazzle ability of the honeycomb grid is good in subjective experience. The light is slightly soft due to the division of the light by the honeycomb grid.

Test conditions: 36°-8W-4000K spotlights, the same shooting equipment, the same subject, the same installation height, the following is the actual picture taken with iphone12 mini, without any processing.

20cm from the wall, straight down,

30cm away from the wall, slightly off Angle.

Take pictures 40cm from the wall at a wide Angle.

The distance between the two lamps is 100cm, and the distance from the wall is 20cm

The distance between the two lamps is 100cm and 30cm from the wall

The distance between the two lamps is 100cm and 40cm from the wall

From the point of view of spot, the ideal illumination distance is about 30cm, and the limit distance of continuous illumination is 100cm, otherwise there will be obvious interference of spot coincidence.

Another interesting thing is that the light spots illuminated by vertical irradiation and declination Angle are different. I use vertical downward irradiation (1) and declination Angle (2) respectively to make a comparison, as shown in the figure below:

20 straight down from the wall and 40 from the wall

The light spot vertically downward (1) is a natural transition from dark to bright.

The Angle of declination (2) has an angular starting point.

From this humble small change, it can be said that the developers poured a lot of effort, vertical downward is usually the use of the wall or wipe the wall, close to the object, the transition of light and dark light, can be a good solution to the problem of hard light spot.

And the Angle of the irradiation, is usually used for painting the scene, the strong Angle of the light can better highlight the object, this design is really well-intentioned, great praise.

Summary of real shooting effect:

Lipro spotlight is a lens light source, the light spot is round, the light and shade transition is uniform, the use of flexible, the use of home is more friendly.

3, all

Lipro spotlight engineering design, from the user’s point of view, to the installation, debugging, multi-scene use and other aspects, made a lot of optimization, so convenient, humanized, personalized at the same time, has a very good light source quality, 100 yuan price rarely competitive products.
