Hi,
I recently decided to have a go at some homemade P60 dropins but stumbled across some problems.
First off I decided to go with a CREE XP-L HI V2 5D LED with a AMC7135*8 1 mode driver (NANJG 105C) rated at 3.04A
Approximated light output:
613lumens @ 1.5A 25°C
1042lumens @ 3A 25°C
Color temperature: 4000-4125K
Everthing soldered up nicely and before going any further I tested the module on a powersource with 4.5V (max input for the driver) and the module only took about 1.8A. Is this normal as the led itself is rated at 1042lumens at 3A?
Second problem I encountered was the fitting of the reflector. I have a reflector with a 7mm emitter opening and one with a 4.5mm opening. With the 4.5 the led is fitted nicely just above the opening of the reflector. The one with the 7mm opening the led isen't even enetring the reflector. THis is probably due to the fact that the ring on the bottom side of the reflector is is wider and doens't give enough space for the leads.
Does someone have a tip how to resolve the problem with the 7mm hole? Or do you know a shop that specificaly sells the 4.5mm reflectors?
Thanks
