What is wrong with the led strip?

If with led lamps is more or less clear and the producers write the main characteristics. That with led strips the situation is rather vague. For example on my existing tapes are not specified such important characteristics as the color rendering index — CRI, color temperature (there are differences) and I'm not talking about light output.

Why don't we start testing strips?

In fact our experimental:

• Smartbuy tape-IP65 4.8 W/WW art. SBL-IP65-4_8-WW 358 RUB.

Twenty two million two hundred six thousand eight hundred sixty seven

Tape for review were drawn from the same power 4.8 W/m (24 watt in the video) and similar to the protection class IP65/66.

GaussCollected efficiently. The diodes are soldered smoothly. On the same tape there is a defect on the silicone (note the difference of gauss labels on the tapes, on the top ribbon, it is fuzzy — this is worn) all over the tape.

SmartBuyThe uneven edges. The tape is thin. Wire soldered crooked.

Fifty one million nine hundred sixty one thousand four hundred ninety seven

 

SKY LARKOn the same tape on the wires a bunch of sealant. The second is not clear that with silicone.

Pass directly on to testingFor measurement we use the spectrometer the UPRtek pulser MF250N

The possibility of measuring:

• Spectrum graph;
• The pulsation index;
• The percentage of ripple;
• Illuminance (LUX);
• Color temperature;
• Color rendering index CRI (Ra).

Thirty four million five hundred fourteen thousand nine hundred fifty three

The power strips will use Robiton power meter PM2

Measurements:

• Voltage (In),
• The current consumed by the appliance (A),
• The AC frequency (Hz),
• The power of appliance (W),
• The number and value of the electricity consumed.

 

Smartbuy tape IP65 4.8 W/CW art. SBL-IP65-4_8-CW 358 RUB.Fifty six million eight hundred sixty eight thousand seventy one

Tested features:

• Power consumption — 12 watt
• Color temperature — 6100К
• CRI — 72

The output of the tape: didn't like the low CRI for cold tape and a little power.
 

Smartbuy tape-IP65 4.8 W/WW art. SBL-IP65-4_8-WW 358 RUB.Two million eight hundred eighty two thousand one hundred forty five

Tested features:

• Power consumption — 11 watt
• Color temperature — 3380К
• CRI 68,5

The output of the tape: warm tape conventionally is a good indicator CRI (above didn't get that far), but low power.
 

Tape SKY LARK 4.8 W/m, 12VDC, IP65, 3000K, 5 m art. SLS-012W048A6508 765 RUBSeventy seven million four hundred seventy six thousand twenty five

Tested features:

• Power consumption 16 W
• Color temperature 3020К
• CRI 54

The output of the tape: CRI is low, power is still not up to claimed.
 

Tape SKY LARK 4.8 W/m, 12VDC, IP65, 4200K, 5 m art. SLS-012N048A6508 765 RUBThirteen million three hundred ten thousand six hundred fifty five

Tested features:

• Power consumption 16 watts
• Color temperature 4400
• CRI 71

The output of the tape: awful color rendering index, power is still not up to claimed.
 

Tape Gauss 2835/60 LED-SMD 4.8 W 12V DC cool white IP66 (blister 5m) art. 311000305 962 RUBFifty nine million seven hundred forty thousand two hundred sixty

Tested features:

• Power consumption 19
• Color temperature 6100
• CRI 78

Conclusion on the ribbon: conditional-good color rendering index, power close to the claimed.
 

Tape Gauss 2835/60 LED-SMD 4.8 W 12V DC warm white IP66 (blister 5m) art. 311000105 962 RUBEighty four million four hundred fifty thousand six hundred fifty two

Tested features:

• Power consumption 19
• Color temperature 2700
• CRI 61

The output of the tape: bad color rendering index, power close to the claimed.
 

What is the result?All lies! But to varying degrees.

All of the tape has not held up to the declared characteristics of the consumption of what can be concluded, that they Shine not as bright as it could. Worst of all in this question things with ribbons SmartBuy. published  

 

P. S. And remember, only by changing their consumption — together we change the world! ©
