I want to replace incandescents with LEDs. Will I be able to measure both without any arithmetic convesrion?

Yes, luminaires do not change regardless of the source.EDIT: Actually what I meant to say is that the meter measures luminaires regardless of the source. Light is light just like 5 gallons of gas will fit in a 5 gallon gas can or a 5 gallon bucket.

depending upon what all your measuring there shouldn't be any math required

As best I understand the question, this sort of comparison is just what the meter is meant to do: measure light intensity. What you read is what you got. Regards,AC

The meter measures the amount of light. To the best of my knowledge the light spectrum is not taken into account. I grow orchids in natural day light so I am not an authority on the best way to go with artificial lighting.

It will take anything with a candelabra base. Big box stores like Home Depot and Lowes are selling both CFC and LED bulbs with candelabra bases now.There's no need to worry about incandescents being phased out since CFCs and LEDs draw so much less power. It's almost impossible to overload an older fixture with a CFC or LED. You can replace any incandescents you have around the house with CFC or LED bulbs as long as they have the same style base.

No. You must use a decent dimmer that's led capable. The old dimmers are hard on the electronics in the led

Unless you are replacing led bulbs, yes. You need resistors if you are upgrading from incandescents to LED

Correct. Incandescent sockets are compatible. Just look the model type up to know what size bulb you need. 95% of my lights are now LEDs.

I'm sorry that I can't say for sure, since I no longer have any 100w incandescents on hand, but it really seems to brighten up my dark entryway at least as much as the old incandescents.

I am sorry that I, as an ordinary consumer/user, do not have A QUANTATIVE ANSWER for your question. However, by comparing this 'new LED' light bulb to the 4-WATT 'old incandescent' light bulbs we used before, its light output is BRIGHTER AND WHITER. I hope you are satisfied with MY QUALITATIVE ANSWER.

Not that I'm aware of. It doesn't seem to be an included feature, nor do the bulbs have an advertised api, which would enable a more do it yourself approach.

beings that an LED uses less energy, thus creates less heat, there shouldn't be an issue, especially if replacing an high-heat incandescent bulb in the fixture. As always, follow manufactures recommended guidelines for safe operation.

It doesn't really matter, why are you asking since the LED needs no servicing and Cree LEDs are now only a slight bit higher efficiency, not enough to matter on a value priced light.

I haven't measured but will tell you that they worked great to replace existing incandescent R20 bulbs in some can lights that we had. I have been happy with them so far.

I'm not aware of a product that would do what you ask. Assuming that the issue is excess heat, I went to 100 watt LED bulbs by Cree. They only require 18 input watts and are cool enough to touch while on. They are relatively expensive, but have a long service life and use considerably less electricity. They are slightly taller than incandescent bulbs, so if that is an issue, you will want to check dimensions before you buy. Website is www.cree.com.

Short answer is no, but in the world of electronics, nearly anything is possible. LED's require a lot less power than flourescents do, so you would probably have to remove nearly all of the components that are in there now and start from scratch. To find out just what would be needed, you'll have to talk to an electrician, electronics hobbyist, or maybe a Radio Shack geek. Any student currently attending a robotics class might be able to come up with a plan, too. Good luck.

I don't have that info with me at this time. However the next time I am at home I can send it to you. I do know that these LED's are the greatest replacements for the standard bulbs that were in our motorhome.

2700K color temperature and color rendering index of 80 are close to as good as LED bulbs get. To completely match incandescent, LED bulbs will have to reach 2700K and 100 CRI. But I have a number of bulbs with 2700/80 that I am satisfied with in terms of warmth vs incandescent, especially considering the superior bulb life, reduced waste heat output, and lower energy costs.

Will work but reccomend instead a Cree LED bulb. I have both and feel the LED bulb is much much closer to the incandescent light output and is aesthetically more natural than the flourescent style bulb. Both are energy efficient and extreme long life.Check equivalent output carefully. 18W LED and Flourescent bulbs produce different amounts of equivalent outputs (something like 45 and 60 Watt incancescent equivalent). As bulbs fail I am replacing with either LED or Flourescent prefering the LED for hard to reach and replace areas--- supposedly longer life.
