E27 G45 2W 4W Amarelo Quente Branco Edison Filamento Economia de Energia LED Lâmpada AC220V

2,56€ 4,98€

Q: Dear Banggood. This product has two different powers (2W and 4W), however there isn't any option available for the selection of the desired LED power. In this case, what it will be the LED power I will receive?

Package arrived in just 3 weeks and in very good conditions. Product manual in both Chinese and English.Personal opinions: I really enjoyed the open CT. Very nice piece. One thing to be improved without significant cost increase: the wires connection and wires (they look and they are very fragile). I ran a test in a eletric panel with this product and a C.A. PEL103. Electric panel had mainly lightning equipments and a few laptops connected (mostly in stand-by). First test result: about: 1,00A in PZEM and 0,94A in PEL (very close results). Power factor: 0,84 in PZEM and 0,76 in PEL (not so close results). Voltage: 233V in both (great results). Power factor naturally affects active power (watts). Second test result (after introduction of resistive load): 4,9A in PZEM and 4,95A in PEL (really close results). Power factor: 0,94 in PZEM and 0,95 in PEL (very close results). Same voltage (excellent results). Conclusion: for a really cheap and low budget equipment I would say very nice results. Do not expect for this price a perfect measurement equipment. I would recommend not to use it with low power factor loads (or high current distortion) because it can affect the quality of the result, specially power measurement (watts). For high currents and high power factor I would recommend the use of this little device.

Nice package. Instruction Manual in English. Nice piece. The "Safe / Harmful" should be removed from the equipment and should only appear numbers and scale. The beep should really only beep at very high levels. Well, in conclusion, the beep function and "Safe / Harmful" in this equipment I think they are simply annoying and stupid. Regarding E-field and H-field measurements accuracy and precision I cannot say how good they are.

After a quick test and for the price I would say nice headlamp. Strap lacks a bit elasticity. The plastic is fine. Box says 3W 200lm but for some reason the picture of the item in the box doesn't match in some details with the 550lm headlamp. I don't know in what to believe. Light is fine and it would the job.

Pieces arrived in time. Very good appearance. I would say good material for the price. I did not have the time to test them.

Arrived in time. Nice quality. For the price don't expect top quality. Keep them lubricated and they should do the job.

Package arrive in expected time. Nice box. Tested a few ones and I would say good quality/price. Very good appearance. Now only time will say if they will keep the pace. If you don't push them with high currents and give them a good tolerance they will probably last.

It took almost 2 months to arrive. Package arrived in perfect conditions. Besides the caliper, it came in a nice hard plastic case with an English manual, a small silica bag and 2 extra 1.5V LR44 batteries. I run some measurements in some good quality HSS drill bits and these were the results: drill bit diameter | caliper measure: 2,5mm | 2,45mm 4,2mm | 4,14mm 6,8mm | 6,76mm 9,0mm | 8,94mm I would say the 0,02mm accuracy in the manual is probably a bit less accurate (about 0,05mm), which I consider not very important and relevant considering the excellent price. I recommend it!

Arrived in record time. I made a few tests and everything is ok. Too much noise can be a problem (like in other similar devices). Instructions manual is in Chinese but you can easily find how it works online.

Package arrived very fast. Each piece is delivered with a nice box. Did not test them. You must take in account seller notes: "If you cut the hard material such as steel, ceramic tile etc. you need to use the oil or water to low the temperature". Keep them lubricated all the time and you will probably have long-lasting pieces.
