Hey Guys,
One of the avionics technicians at work put me onto super bright LED modules.
As they were very bright I tried one out on an egg in full light and I was impressed.
So I built a purpose made candler

It is quite simple to build, you need a project box, led module, a focusing lens for the module, a constant current LED driver module, a push switch, some 25mm conduit, wire and a battery.

with the lights on and no flash, the egg is an un-incubated one.

and the lights off
Now the parts are reasonably expensive and it would cost about 40 dollars to build one, but it works great and it doesnt produce the same heat as a normal light bulb of the same brightness.
Regards
Trev
I like you candling very much: Where to get all the parts you used to build it? Pls specify items.
However your incubator wont work as the reptile thermostat max temp is 35C. You will need at least 37.5C. (101F). Is your thermostat max 39C & minimum 37c? I usually set mine at 38.4C to 39C. Can you tell where to get the 37-39C: cheap one such as your reptile one which about $40.00. I have 1 now which costs me about $130.00 (from Ebay). It can be set to any temp with an alarm on to warn you the set temp is off range (-/+). I want to build 2 or 3 more to give to friend. That is why I need a cheap one. Thanks you for your attention.
