I have replaced all of my gu10 50 watt halogen bulbs with 60smd 4.5 watt led equivalents. These are 120 degree angle, so a much wider pattern than a 38 degree halogen. Regarding colour temp. 3000k is a yellower light, which appears brighter when reading as more of the light is the same colour as the paper, so more gets reflected and is perceived as being brighter. The lumen levels are 320 on the 3000k but 350 on the 4500k, yet because of the yellow/white paper,the 3000k is better to read with. Your eyes will adjust to the 4500k light, but after years of optical conditioning from incadescents, it takes some getting used to. I do find the 4500k to give a crisper sharper light. Just for reference, a gu10 50 watt halogen puts out 80% heat and 300 lumen of light.

Any ebay seller that fails to mention how many lumen and just keeps pushing the watts quota is selling an inferior product.

I am currently buying the 60smd 4.5w 320 lumen bulbs for £4 a bulb. You have to buy 12 at a time. This is much cheaper than my local electrical wholesaler, and a much better product.

Default LA19DM/LED failed


One of my 40w LED lamps failed last week.
Shop Utilitech 40-Watt Equivalent Indoor Warm White LED Light Bulb at Lowes.com

Amazon.com: LED 40 Watt Equivalent 7.5 Watt 430 Lumen A19 Dimmable Light Bulb 3000K: Home & Kitchen

It was in the desk lamp that's plugged into my PC's Smart Strip (a prize from Ecorenovator)
The Smart Strip switches the power to the lamp off and on dozens of times during each day..
Maybe the LED PS can't take that kind of hammering??
None of my other A19 LED lamps have failed.. Yet..
(I own a dozen, and 7 are LA19DM/LED blubs).

The LA19DM/LED has a 2 year store replacement warranty printed
on it's plastic box, so I saved a couple (with the receipt), just in case..

Lowes gave my wife a refund and she purchased a new one for $12.

I think LED efficiencies are getting better, in this case at least.

This website

SSL Lighting Facts

explains a new label on light bulbs showing their color range, lifespan, etc.

Don't buy a CFL or LED without checking it out.

Default We need more government!!

That's great. The cost of course will increase to cover the cost of new government regulations.

I've found that buying any new device is risky, if you rely on the government for your information.
Like expecting the EPA to provide accurate MPG numbers!!

IMHO, one should look at the specs that have been verified by owners,
and then read as many product reviews as they can find.

Then, buy from a vendor that will take care of you if there is a problem with your purchase.

I've found that both Lowes and Home Depot are very good with store replacement warranty claims.

I think it is better to get info from an independent testing source rather than simply relying on the information provided by the maker of the product. After all, they DO have a dog in the fight.

Unfortunately, other than a testing lab funded by the product manufacturer, or an entity like Consumer Reports, the only independent source with funding is the Government. It is foolish to assume that the GOV is incompetent. We make it incompetent when it is given a mandate and then no funds to implement that mandate.

Generally, you get what you pay for. The dollar store CFL/LED's are lousy; they hum, give off harsh light & don't last. Purchase those made by Cree or Phillips or another reputable manufacturer. For alot of people, the color of the light is more important than the energy savings, so the LIGHTING FACTS label helps the consumer understand what the actual product does. If it costs .02 cents more, on a $40 bulb, that is fine with me.

Well, these Sylvania A15 8W 450 lumen bulbs are not inexpensive, but they are dimmable and they seem very bright and clear:

https://www.sylvania.com/en-us/newsr...LED-lamps.aspx

Shop SYLVANIA 8-Watt (40W) A15 Medium Base Soft White (2700K) CFL Bulb at Lowes.com

The top of the bulb is actually crystal clear, despite how this image looks:


They are usable in ceiling fans (which is actually what I got them for), and they work very well indeed in our stove hood.

I'm still using this one.. Shop Utilitech 7.5-Watt (40W) A19 Medium Base Warm White (3000K) LED Bulb at Lowes.com


Mostly because of it's low cost and the liberal store replacement policies.
All of them are over a year old now and seem to be doing well.
A couple failed, as did a couple of the decorator LED lamps.
The infant mortality stage seems to have passed..
All of the 60W bulbs have done a good job without any failures. But I'm only using a few.

This one from HD is still my fav...
12.5- Watt (60-W) LED A19 Soft White (2700K) Dimmable Light Bulb (E*)-422154 at The Home Depot



Saw this in a review on HD..
Connecticut Home Depot has them at half price due to “Connecticut Energy Efficiency Fund”
