is it a big difference between the 2100k bulb and the 2700k bulb?

Honestly the difference isn't noticeable..... I will say that I have this 250 next to my mini 175watt sunburst ($80) and the sunburst blows it away... The cfl needs to be too close and the plant growth is half of what I'm getting with the mini sunburst.... I'm wishing I would have got another instead of this larger watt cfl.... Just food for thought...

Never tried 2100k depends on your plants I guess do a little research online and figure out which spectrum is best for you

The 2100k is redder good for flowering, the Apollo 250 is awesome! to see the real difference is to see a 6100k is whiter and good for veg.

It is VERY noticeable, I have a 2700K and a 2100K right next to each other and the 2100K has more blue added to the spectrum, the visible light is somewhat purple whereas the 2700K is very red. The 2100K is marked "for veg and flower" I've never tried using it by itself but I imagine it would make a suitable light if you could only afford to get one bulb, it's not ideal for veg but it'll work and it's great for flower.

Sorry, I haven't tried the PAR20. I wasn't concerned about the depth of the bulb, so I went for the higher light output of the 423400.

My personal thought would be to go with the "whiter" 3000k. If you put a dimmer on the switch, it really won't be an issue as the brightness will be adjustable.

Yes, this is basically the same bulb only now instead of the IR reflective coating they use a special gas mixture to raise filament temperature and achieve a higher light output. The socket should be the same though.

Warm white is more like an incandescent lamp, slightly yellowish. I'm no expert, but I have another LED with 2700K; it's slightly yellow. The lamp in question is not at all yellowish, nor is it as blueish-white as the fluorescent tubes I have as my main ceiling lights near this one.

Yes essentially, the only difference I can tell when installed, is the area that emits light is a slightly smaller diameter than the standard bulb. This is barely noticeable differencein my recessed light.

They are the same bulb, only the packaging is different. Both are 10 Watts, produce 940 Lumens, 2700K color temperature, 94 Lumens per Watt.

I responded recently that the color temp is slightly whiter than the halogen color temp. When I replaced three of them above our vanity she complained that the new bulbs really washed out her mirror reflection, so I put one of the originals back in the middle socket. The combo was satisfactory and saves us a lot on electricity. But I cannot answer your question quantitatively.

Those are the Kelvin Ratings. The 6000k is usually the most popular. The higher you go in the Kelvin Rating, you get more color in the light in exchange for visibility. So 6000k will be just slightly brighter than 8000k and 8000k will be slightly brighter than 10000k and so on but they will have more and more color to them. Its completely up to your preference on which one you choose. Hope that helps.

well im running 450w 10's and I have the gain a little under half way and it slams with the 3100. with your 2100 maybe you can just bridge it to get the wattage you need.

You can select a 2700K bulb for this fixture when you check out. Although I haven't used this particular light for that purpose, I'm sure the 2700K bulb would do great for the growth and flowering stages.

I just received these to replace a 2700K bulb. While the package says these are 2700K, they're much whiter than the bulb I replaced. Too white in my opinion.

It's not a matter of brightness. Both emit the same # of lumens. It's a function of the light spectrum they emit. So it's really an aesthetics question. Some people don't care for "white" that's in the 5,000K range and prefer the "warm" or yellowish light emitted at 3500K.

I do not know if they are 2700K, but I replaced half inch string and they are just as bright, probably a bit brighter, but not too bright to need a dimmer (in my view) Yes, they can be dimmed with a separate dimmer, but quite expensive (call the seller for details).

The 6500k is a measurement of LIGHT OUTPUT -- it has NOTHING to do with the temperature (F. or C.) of the bulb or the room it's in !! The 27-Watt-bulb can be touched with the Lamp "on" -- it won't burn anything or anyone.

From what I can tell the differences are the lumen output of 1038 vs 1200and the color range of light from 3000K vs 4000K with the 3000 being a warmer lightand the 4000 being a cooler whiteThese are the main differences that I see-

It will have much lower current draw, be brighter and fit. Bulb life is also in the thousands of hours. One of my best changes.
