Hi all,
I'm obviously new here. What brought me here was a need to design, from scratch, an LED system to light up a fiberglass tube from the inside. Cost IS absolutely a factor. However, if it won't do the job, it doesn't much matter what it costs, does it?
Parameters:
1.Total diameter not to exceed .900"
2. Run time on fresh cells= 10hrs or more
3. This is the only one that I'm having trouble being specific on. All I have so far for a reference is a Garrity Steel Beam AAA. It illuminates the tube, but barely. Not acceptable. The Garrity is bone stock. I've searched to no avail to find a spec on the Garrity for its candlepower or luminosity, so I couldn't compare a commercially made light to see if one that is mass-produced would work.
So, what I'm asking for is a parts list or schematic for a cost efficient LED circuit that is VERY bright white light. I've read on this board about heat becoming a factor at some point. The system will be housed inside PVC then installed in the tube, so airflow for cooling will be nill.
If any of you are familiar with it, what I'm constructing is similar to the way a borescope works, except this one will be housed inside the tube it is illuminating.
End result if done correctly----fiberglass tube will glow "brightly" in the dark!
Any help you could provide would be greatly appreciated as all of you have much more experience in flashlights and their construction, than I do.
