Is iclear 30 and Lemo use same exact coil and wick set up and are you firing them at same exact wattage?? Because iclear cant handle high wattage, iclear30 is max around 10 watts, while Lemo can go to 40 watts.

More wattage = MORE HEAT.

True, but you have more airflow on the lemo, no? in which case your coils cool more as you draw so it can handle higher watts and stay cooler.

Yes the holes are bigger and give you more cooling if you go watt for watt. But in my experience, even larger holes (100% air flow increase) on Lemo will stick give you a very hot vape.
And with stock air-holes on Lemo at 40w, its like drinking hot liquid.

Wow have we gone on a tangent over here. Okay sounds good, I will just have to get me a higher % VG juice. Just seems strange, the same amount of vapor is produced from both my atty's but only the RTA comes off pretty harsh. BTW I am running stock coil, tho i re-wicked it with some Japanese cotton. Think I might change the build next time I drain it, more ohm, like 1.8ohm. Thanks ask who responded!

maybe due to larger coil surface area?
Also the atomization chamber on a lemo is bigger than an iclear, right? I'm just shooting in the dim here.. got an idea how all this works but not for sure - speaking from experience more than science at this point... and I have no experience with either atty :)
Someone else with more experience/knowledge feel free to chime in and take over!

Everything about Lemo is bigger; air holes and you can have bigger coil. But depending on the coil build on the Lemo, you can have cool wave or warm vape at same wattage.

You didn't wash your atty first? I always disassemble new attys and wash them with dawn and hot water (as hot as I can get it out of the tap without cranking up the water heater!) then rinse really well and let air dry. I used to rewash them every few weeks, but I've gotten REALLY lazy lately, so now I just occasionally give them a good hot rinse before rebuilding every month or so.

Im confused. Whats using the 1.8ohm coil?

Make it simple.

Battery mod/box - ??

1. Iclear 30 - __ohms - __watts

2. Lemo - __ohms - __watts - __wire guage

Pure and simple, anyone know why, at least to me, it seems every time I hit a rta or RDA mouth to lung it seems really harsh unless they are using a high percentage VG liquid. Any particular reason why? I can hit my Iclear 30b and then hit my Lemo with the same 50\50 mix and it just seems harsh to me. I have used people's rda's and they work fine unless it's more than mix, then it's very harsh. I don't seem to mind PG in cartos or bottom coil tanks, but rebuildables seem to act different. Now a lung hit with a Lemo is fine, regardless of the mix %. Any info would be greatly appreciated. Thanks!

You can hit your Iclear 30b at 5 watts
and then hit your Lemo with the same 50\50 mix at 10 watts and it just seems harsh to you?

Nastie, no I most certainly did wash everything before I tourched the coil, put it back in, wicked it and reassembled.

1.8ohm is for my next build on the Lemo.
Iclear 2.0ohm 9.5w
Lemo 1.1ohm 11w, no idea the wire, 26+gauge I assume.
Firing both on my MVP 2
I have 28gauge wire I will be using for my next builds, if not I have 30 around here somewhere.
But the question had to do with RDA RTA in general, not just mine specifically.

Now ya I can understand how a bigger deck but obviously give me more condense vapor, making it a bit harsher.

You got 1ohm difference in coils, so there will be vape difference as well.

And if you are using MVP2 then are you using same Voltage setting for both tanks?

So 2 ohm 9.5 watts on the iclear
and 1 ohm 11 watts on the lemo.

If the lemo is harsh and hot then I doubt that it's 26 gauge. Maybe its 30 or 32; maybe it's not even kanthal.

if its harsh but not hot, maybe it's more of an airflow issue;

In my experience 30 ga isn't ideal for larger airflow devices as the coil has less surface area so you will get more intense heat on a smaller surface area of the wick and the airflow isn't being utilized to its full potential. 28 ga is probably fine with an InnerDiameter of 3/32 or so for a dual coil, much larger and you loose the surface area on the coil, so less vapors i think.

Also, harsher is probably more to due with the volume of vapor more than the density, but I haven't played with that theory much.
