I still need to solder everything, I'm hoping the angled heatsink + led optics will make a difference and not have a spotlighting effect. I'll prob have everything wired up this weekend.
Thanks, I really like your design as-well. I think I watched your video 10xtimes, in order to come up with my design. roud:
The kit I purchased did not come with a dimmable option, I might in the future go for it. In regards to the optics I think your right, I'll probably keep optics on the "angled LEDs" to try to "push" as much light as possible into corners of the tank.
i did not use thermal adhesives, rather i went with metal screws and tapped threads in the heatsink. I did use a dab of artic silver under each pad though.
you would be safe using the thermal adhesives, no need to tap & screw ( i have a tap set so it gave me an excuse to use it ;-)
Great to hear! Thanks again. Can you point me to a good dimmer? Any advantages to dimming the led's? I know longevity, life of the led's is improved, anything else?
LEDs die by being overcurrent and of course how many hours they are driven, since these have a MTBF of 50K hours you will grow old and gray before they crap out, so no worries if you did not dim them. Dimming only gives you latitude on intensity, and of course dusk to dawn effect.
Thats good to hear, I might just keep it simple and go without dimming them. Now to find a large computer fan like yours. Luckily I have a large DIY electronic store in the area which have computer fans in all sizes.
