- This IPL (intense pulsed light) hair removal device was found to be fully working except for the quartz flashlamp, which costs about $45 to replace (for 750 pulses). When new about 10 years ago, the machine would have sold for about $350-500! These devices work by heating hair follicles with intense light and destroying them, but they are not recommended for darker skin which blocks light and damages more superficial layers. Unlike the previous device I tore down (Tanda me by elos), this one doesn't seem to use radio frequencies. The quartz flashlamp also appears to not have any "smart" chip in it leaving me to wonder how it counts the number of pulses remaining in the lamp. An important lesson to be learned as well in the video is that you need to be careful discharging capacitors. Starting at 2:50 you can enjoy sparks flying as I discharge 3 large caps! Normally you would use a gentler method (alligator clips on large value resistor) to slowly discharge them to prevent possible damage. Since this was going in the garbage anyways I didn't care. Once again a fascinating teardown with quite complex electronics and even some kind of skin color detector (7:40)!
Looks very nice inside.
True, they put way too much effort in designing and building this. I never expected it, but this is not a typical self-care appliance. I believe it's more along the design of a medical health device so they spared no thoughts and cost in the complexity of this build.
The sensor is to determine whether or not you actually have the wand if you want to call it that up against your skin because you don't want to have that flash in the open air to potentially harm somebody's eyes That's what the sensors for also to determine if you if you have the wrong kind of skin it'll sense that and it won't let it flash. So it's for safety reasons.
Thanks for the explanation, that makes sense!
As far as the lamp being limited to 4000 pulses I think you said I'm not sure what the region for that is but I do know that if you do some searching on the internet you can find lights that the data chip in it has been modified and you get 10,000 pulses or 20,000 pulses or whatever it is. Is it dangerous to do that? I have no idea.
There could be some degradation in the lamp and perhaps after certain number of pulses it's energy output curve or spectrum/frequency distribution may drift and start to become unsafe to use? Why not just use it until it burns out? Unless the burn-out process itself could be dangerous (like an exploding bulb or some other issue). This also could just be a way to make sure they keep consistency in the results of the product and give themselves a continuous revenue stream.
