10 watts, 625 lumens, 3000°K
The package graphic almost-correctly indicates similarity to a 50 watt incandescent BR20 flood, perhaps this current offering at amazon .
Here is naive advice from Green Creative , that gives further understatement of the task illumination achieved with this light. The comparisons are with point-source bare bulbs.
The table implies that a useless 50 watt bulb corresponds to a 625 lumens LED downlight. In fact, a 625 lumens LED downlight corresponds to a 140 watt point source light bulb.
Unpackage a GreenCreative LED 4" Downlight, Product 40834.
I want to put the luminaire on my test stand, mounted to a junction box. Employ a quick-connector male end from my loose-parts inventory.
The flush side of a three-pointed bracket will be set against the ceiling of course, for junction-box mounting. This is the reverse of orientation in all installation drawings.
Box labeling includes the word CLICK. Here a luminaire is Clicked to the bracket as it would be assembled for can light mounting. The deep side of the click slot is set upward.
At Stage Right on my test stand I employ two RACO 175 junction boxes. That fully visible here is at the same elevation as a junction box at Stage Left. Fit the upper Stage Right junction box with a porcelain lampholder for test of various light bulbs vs. GreenCreative 40834 at Stage Left.
GreenCreative 40834 might be more than 625 lumens. The color temperature of 3000°K is a remarkably good match.
The GreenCreative 40834 dims smoothly, to a lesser light level (better) than Nicor DLS4. Both luminaires buzz as energized through a very-good Cooper DAL06P dimmer.
The buzzing of the GreenCreative 40834 is about twice as loud, but might not offend you.
Review now, one more labeling of the package front, the claim Estimated Energy Cost: $1.20 per year. This is 3 hr/day*365 days/yr*10/1000 kilowatts*$0.11 per KWH. The number does not inspire. Better, calculate the money this light will save you over its lifespan of at least 40,000 hours. Consider replacement of 100 wall bulbs on a dangerous porcelain fixture, and replacement of incandescent of fluorescent BR20 flood bulbs in a 4" can light. I have offered unique math for this, until now treating the cost of electricity as fixed forever at current 11 cents/kwh.
GreenCreative BR30 7.5W Cloud,avalable somewhere as Soft White 3000°K.
BR30? A19? Expect up to 14 watts in your purchase, less-pretty 2850°K, and unsure survival of a drop.
If you would retain a 4" can for your light, an inexpensive LED bulb achieves the savings, with least effort and installed cost.
If you start with a safe but jam-packed ceiling junction box, and can't replace that box, choose a Lithonia LED Versilite or GreenCreative 40834 dependent on your style preference. Many people will prefer the GreenCreative 40834 for appearance.
There are many adequate choices. Just be sure to stay with LED and someday OLED, from now on. There was no joy in the jungle of incandescent, halogen and fluorescent bulbs now past.
A menagerie of twelve light bulbs at the higher position Stage Right on my test stand, is compared with GreenCreative 40834. Note the ordering as for the cluster of four bulbs below. Two similar 65 watt incandescent spots at left give less-pretty light perhaps a bit brighter than GreenCreative 40834, but in unintelligent cones, concentrated with 60° beam angle. Light for general illumination, not upon some object, serves best with maximum beam angle. At lower right see awful illumination from a "65 watt" CFL spot. At upper right, see that GreenCreative 40834 is much brighter than a 100 watt incandescent bulb. All comparisons are in a dimmer circuit at full power.
Of twelve lights in these photos, only the Cree 60-watt LED bulb, lower-right below, is dimmable. A 300 watt incandescent bulb, upper right below, is brighter than GreenCreative 40834, fragile and very hot.
Good riddance to all of these bulbs. Good riddance too, to the awful fruit of the L-Prize, among LEDs tricked to act as point-source and very poor in directional application.
GreenCreative LED 4" Downlight, Product 40834, at stage left again, is very superior to an 800-lumens Utilitech response to Philips L-Prize bulb , dead end beaming as it would, placed overhead to light a room. An LED bulb, tricked to act as a point source is uncompetitive for efficiency in practical illumination. We shall wish that the US Department of Energy would do something useful in the advancement of residential LED lighting.
