RRT-1 Raptor Lag

[DimeRazorback]

I received my raptor today, and i love it so far.
It's dark now and i decided to test it out.
Boy does it throw!

But i have noticed one little thing, and i want to know if it is normal.

I have noticed lag with turning the light on.
For example, if i momentarily turn it on it quickly flashes with really low output, and then goes to either low, medium or high, depending on where the selector ring is of course.

So in summary its like this:
*Press switch* Black > really low output > black > selected output.

Now this happens within half a second, VERY quickly, but it is noticeable.

Do they all have this, delayed, weird characteristic? :thinking:

Or is there something wrong with mine? :shakehead

For the avoidance of doubt, could you confirm that your light is a RRT-1, and not a RRT-2 ?

RRT-1 100% :thumbsup:

Reminds me to update my sig

I believe that they have the same circuit, i.e. the delay will be the same.
On the RRT-1 it has a 20uS flash, then 0.12 sec pause before turning on. I have not measured the delay from power is applied, until light.
I can see on the RRT-2 it also has a slow turn on, but I have not done any analysis yet.

Thanks HKJ!

Thats the sort of answer i was after.

So i take it that it is just the design of the circuit.

Would you happen to know why it was designed like that?

I do not not know why the RRT has exactly that delay, but more generally what is happening is that some capacitors need to be charged, and the controlling microprocessor need to initialize itself. Depending on circuit design and programming, these things can be very fast or take bit more time.

Ah ok :thumbsup:

Makes perfect sense!

Thank you for your help, and for putting my mind at ease!

Sorry to say :shakehead....I have zero lag in mine. Not during initial on...on any of the settings...not during switching...not ever. Perfect and immediate on. My ring is not loose and nothing rattles (as I've read with others at times). :thumbsup:

I have now measured turn on delay on both RRT-1 and RRT-2 and it is about the same.

RRT-1:

RRT-2:

Red is current and blue is light. At 0 it has an initial current spike and a small flash, then after 0.12 sec the light turns on.

Initially it was said that the delay was within .5 of a second and it came on low - went blank - then turned on to the power setting. Then it was verified at .12 of a sec. I've about worn out my switch trying to duplicate this by eye - how in the world did you notice this in the first place? I then tried to click the switch real slowly and I did notice something but it was an almost imperceptible initial flicker. When I hit the switch as I normally do (about as fast as the flicker ), everything happens so quickly that it seems immediate on. Sorry . I would have never noticed - only problem is - I believe now...I will be looking for that flicker every time I turn in on .

Great work with the graphs...I can only wonder at the equipment you must have in order to create them...:bow:.

The clue to discovering it, is the initial flash, then it is simple to measure the delay (with the right equipment). My first measure was only the light, this time I also included the current draw, to look for additional delay when turning on, but it does not look like there is any additional delays.
It is not a good idea to try turning the light slowly on, it can be hard on the switch.

Excellent work HKJ!

I love seeing evidence and proof, and that is proving EXACTLY what i thought i was seeing!

Tora, I'm a fairly detailed person and notice things that others tend to look past, or would neveer even notice.
