PriceI spent RMB 79 to buy this LED Grow Light Bulb in IKEA Guangzhou. Sometime you may spend more in your location. From 10 Eu to 15 EU.
|Manufacture||LEEDARSON LIGHTING CO., LTD|
|Input Voltage||220 - 240 Vac|
|Input Current||95 mA|
|Warming up time||--|
|Standard/ Safety Mark||IEC 62471. Intertek, CE, Rohs, Reach|
|Dimension||95 mm X 115 mm|
Here are package view and detail dimension. Front view, PPF is in of you. It looks like PAR30 type, detail dimension looks below.
Side View, some safety symbols for your reference.
Side View, what does this mean? Haha.
Side View. It is good, there are many LED bulbs which are met the Chemical requirement.
Top View. The lens look good?
Inside View. Once you take the LED Grow Light out, plastic housing, the color of housing look cool.
Now, let me measure the dimension, here is the max OD, it is 95.48 mm.
Maximum length is 116.41 mm.
The CE logo is 4,99 mm.
Though I can see the letter clearly, but it must be more than 3 mm from the Lighting Standard.
The WEEE seems wrong, must more than 7 mm, but in EU, not in China. Hahaha.
The lens dimension is 87.50 mm.
One small Pcs lens is 13.47, sorry my picture, it does match.
The Lamp cap is 26.25 mm.
The tip point is 9.51 mm.
The neck is 39.89 mm.
The thickness is 5.62 mm. Why do they design this? It is too thick， good for heat dissipation?
From the test, the power factor is 0.5, it is not good, but seems in China, there is not requirement. While it is more than 0.7 in the EU and USA/CAN. Like all lights, these are rated in Watts, and the higher the Watts the more light power you will get. If you want wide coverage and deep penetration through the thick brush, then choose a high Watt lamp. 24Watt is a normal range to expect.
|Input Voltage||220 - 240 Vac||231.8 Vac|
|Input Current||95 mA||86 mA|
Temperature testAs you may know, the thermal management is really important for LED light bulb.
|At the beginning||1 hour later|
|LED Chip(White, Center )||101||141.3|
|LED Chip(On the edge of LED board )||--||115|
All LED grow lights are tuned to produce light spectrum that is suitable to promote plant growth. Many want a normal LED white light, but instead these are blue and red.
In the below picture, you can see there are total 13 LED Chips on the LED board.
If turn it on, looks good?
Take a photo by Camera. It seems wired, on the edge, it shows yellow color? Why ??
The Red LED Chip, looks like a pancake. There is a white ring on the edge. We quite confused about the picture.
Ok, Use the Everfine SPIC-200 to test lighting spectrum. The CCT is 4000 K. But the product package does not show this, on the package, IKEA said, it is not for general light purpose.
Take a close look at the color ratio. The Green ratio is more than 73%, we know, it is no use for most Greens. Though recently, some studies found it is also useful. But 73% seems too much.
Here is test data on the CIE 1931 Chart.
Here is test data on the CIE 1976 Chart.
Here is the ANSI standard. Out of Chart, but this is not GLS from IKEA declare.
The Color Render is very good, look at the Radar Chart, most are more than 95, except the R12 is 81.
Here is the bar chart for R1 -R15.
If you know to the testing equipment, go to this post for detail. Link. We follow the char on the package, max height is 26 cm. The LED Grow Light Bulb is on the top Center, there are 20 PPFD points on the Bottom.
PPFD Chart Data, you you refer to below chart, 110 mm x 120 mm. For data, all are more than 200, the max is over 600. For some leaf green, it is okay.
What are these data used for ? Basic light photon for some green is 200.
Remove the Lens, with a tool, you can see the LED chips. IKEA seems like this type connector, it is easy assembly.
Unscrew the 3 small screws, remove the LED Board, the Heatsink is under the LED board, you may understand why the temperature is high! No adhesive also.
Remove the Heatsink, you can the LED bulb, no surprise, the LED driver is so simple.
Remove the Lampcap, pull out the LED Driver, all part. All these cost 79 RMB??
LED Driver Back View, the Driver IC can not be identified.
LED Driver Front View， only 4 components!!
Here is weight of each part.

Sumarry for this bulbI would not buy this one. If you go through the post, it is good choice. In fact, it is not a LED Grow Light. This bulb are just White LED Chips and Red LED Chips.
Compare to others bulb
Compare to IKEA VAXER LED1505R6 Grow Light Bulb Review, in my opinion, they have similar construction. Both of them can not be defined as LED Grow Light. So what is the good Glow Light to plant?
