Side View
LED Driver is from MEAN WELL ENTERPRISES CO LTD(E334687 on the UL R/C Product). It provided with integral input and output cord.
This LED driver model is HBG-100-48E. 100-240/277, 50/60Hz, 1.1/0.45A, LVLE, 49 Vdc, 2.0 A, use for WET Location.
In the United state, From the UL 1598 and UL 8750 Lighting standard, the diffuser must have f1! Since factory claimed it has earned UL Certificated. It may be had, but please be awarded there is trick for this. We can call this liar.
If you want to go into details, in fact, I hope you can do it. You can required the factory to provide the UL Report to you, you can check in detail, and verify it in the UL.com.
Side View
You can find the Heat Sink, make of Die-cast aluminum, secured to LED Driver by four copper pillars with screws. There is a gap between the LED driver and heat sink. Why do the factory design like this? The LED source too hot?
There is a Aluminum sheet . Mechanical seured to the heat sink. Check below picture, you can find it.
Back View
Unscrew the screws, you can see 3 different parts.They are diffuser frame, Transparent Diffuser and Gasket. Diffuser frame is made of Die-cast aluminum, secured to Heat Sink by screws. The silicone rubber gasket is sandwiched between the Diffuser Frame and Heat sink.
The transparent diffuser is measured 1.5 mm thickness, no idea for other parameter.
Dissemble View
The LED Board is aluminum base, 2.0 mm thick, rated minimum V-1(on the board), 105°C, secured to Heat Sink by screws. Overall 100 mm diameter. The wires connected to LED Board were covered by adhesive after soldering.
There are total 210 pcs SMD LED chips. 3030 Type. Claimed form OSRAM 3030.
COST
We try to find the BOM Cost. It is near $100!!! If you buy from the e-com website.
