DIFFERANCE BETWEEN t8 AND T12 FLOESCENCE

Smaller diameter bulb as discussed in a prior reply. I had new fixtures installed to replace the old buzzing ones. Keeping these on hand for random replacement is easier than getting one or two at a time.

The T number refers to the diameter of the tube. A T8 is 8-eights of an inch in diameter - that is 1". A T12 is 12-eights (that is, 1.5" in diamter). I believe T12s are being phased out, because of energy efficiency. T8s use less power and deliver the same amount of light as a T12.

sorry, I have both kinds and I can't remember which they use. I got them for my greenhouse. I'm pretty sure they were T8 because those were the types of bulbs I had to buy but I can't guarantee it. It seems like the bulb type was included in the product description. The lights are very lightweight and come completely assembled which is nice.

T-8, you can find T-5 at Foster and Smith or Petmountain for a reasonable price or try Lightyourreptiles.com

I bought four of the same type. Not sure that it really matters much if you are setting the white balance of your camera before shooting. That should compensate for differences in light spectrum.

There is a very slight and dull glow with the 500. The 600 has zero glow. Both are excellent. I have a 500 in a free above the deck. It is almost invisible.

I don't know. I use developer and kaleidocolors powder to lighten, then use t18. Unsure of how it would perform under different circumstances. Sorry.

It's actually more opaque but not completely transparent. You CAN see the fluid. Hope that helps.

E11 is the base type and T3/T4 refers to the halogen lamp itself, not the base. I use 100W and 150W T4 type halogen lights with E11 bases. Hope this helps.

I honestly don't know the answer to that question, I am using t inside and I really don't notice a difference between this bulb and less expensive ones. Sorry I couldn't help you

They tend to give you a slightly brighter exposure, for me is like opening 2/3 to 1/2 of an f/stop more. As far as skin color rendition no difference at all!

But looking at the description it has TF in it. I would do some research and see if it is the same thing.

8 DPO but it was a very, very faint positive. I didn't get a dark positive test until about 11 DPO.

OxyLED T100 emits cool color (color temperature is 5000k ) light only while T120 emit both cool color (color temperature is 5000k ) and worm color (color temperature is 3000k) at your prefernce

No way to know for sure. But I think the whites are 65K and the blue side is actually about 20k. There is no actual actinic blue channel.

since you asked i compared it with other toothpastes i have in the house. opalescence has .25%w/v which is about the same as in colgate total and kid's crest. sensodyne has less (.15%w/v).

As far as I can remember, my B-Cure emits a fixed wavelength of 808 nm. It seems to work well. Other laser companies say a combination of 660 and 905 nm can address deeper tissues. It's hard to know what works best.The green LED contact light periodically fails on mine (it's "on" this week), but, the red glow of the actual laser is still fine (visible in a dark room) - after 15 months of use (twice daily at 35 minutes per session) on my right knee.-Brian

8dpo was very very faded....most of the time I get a faint line at 11dpo(I have had 2 healthy kids and three angel babies:(,,, ). BUT it does depend on your LP which varies from woman to woman my LP is usually 13dpo. I have noticed a LOT of fades with these dip strips but they are better then the blue dye tests(they are really bad). Good luck and sticky baby dust!
