|Part NO||Emitting Color||LED Wattage |
LED manufacturer's wattage rating
|Intensity per LED||Intensity||Beam Angle |
Beam angle is used to express the width of the light emitting from the source. The narrower the beam angle the more focused the light energy is. Comparing two 40 watt lights one with a beam angle of 30(a) and another with a beam angle of 90(b), They both produce the same amount of light output but (a) will appear brighter in the beam angle compared to (b) at the sacrifice of light spread.
Royal Blue is binned by radiometric power and peak wavelength rather than photometric lumens and dominate wavelength
|CCT / Wavelength |
CCT is used to express the color or shade of white light. The Correlated Color Temperature is the measure of the color appearance of the light emitted from a light source, measured in degrees kelvin (K). The CCT rating is a general 'warmth' or 'coolness' measure of its appearance. Wavelength is used to express a specific color of light other than whites. Wavelength is the portion of the visible spectrum that the human eye can detect, between 380 and 700 nanometers (nm). When trying to match an existing bulb color choose a replacement that most closely matches the CCT or wavelength of the original.
|CRI ||Luminous Efficacy |
A unit of measurement for how effective a light source is in converting electrical energy to lumens of visible light.

Nice output, but what's with the buzzing?
I used 2 of these bulbs in a single display cabinet to replace the halogen G4's I had been using the past few years. The main reason I wanted to replace the Halogens was the high heat output they had been giving off.
Well, these LED's seem to have solved the heat issue and they're nearly as bright. My best guess would be that they're about 80% the brightness of a stock off-the-shelf halogen G4.
However the biggest issue I have with these so far - and the reason they didn't get 5 stars - is that each of the bulbs I bought a producing a low volume, high-pitched, consistent and unrelenting electrical buzz. It's quite annoying initially after the dead-silent halogens for so many years. maybe it's something I'll get used to, but I honestly cant understand why they're buzzing. And since both are doing it, I cant imagine this is a manufacturing defect, but something inherent in the design.
They are in an enclosed cabinet so that too muffles the noise.
Thanks for taking the time to right a review on the G4-CWHP10-D. The most likely cause of the buzzing is how the bulbs are being powered. The G4-CWHP10-D operating voltage is 10-30VDC and in most applications like yours the supply voltage is 12VAC. The noise is the bulbs driver trying to compensate for the AC power. This will greatly shorten the life of the bulb.
The G4-xHP10-DAC operates on 12VDC or 12VAC and would be a much better choice for your application.
