Hi,
I have a Heath Zenith Dual Brite motion detector that is controlling 3 Par16 LED lamps. When I replaced the old LED lamps with new ones, they started to flicker. I have been lead to believe that the minimum holding current for the triac is too high, compared to load of the lamps, as they are more efficient than the old lamps.

I have been trying to find out the specs for the SanRex T10E6F triac, but have had no luck. Is it just a matter of swapping out the existing triac with one that has a lower minimum holding current or will the circuit have to be modified as well?
Thanks!

 

Can't find the specs.. but if the led lamps are using less current, then a simple resistor in parallel with the new leds will increase the minimum holding current.

I thought of that, but if I do that, I will loose any efficiency that I will have gained by utilizing better LED lamps.

 

Ok try a BT136 triac...
