    *POLL* How long do you think a T5 tube will last?

    I am interested in knowing as the growth in my tank has slowed alot over the last few months.

    To buy cheap or expensive T5's

    It is a 120 or so gallon. I had poor water turnover at 8x. The next setup will be 30x

    To buy cheap or expensive T5's

    I am wondering if you guys would share your experience with using cheaper t5's compared to those of a higher price? I am running some cheap ones and I didnt have great sucess with them. I did not have a very nutrient rich substrate but fed to the water colum. I would like to know so I can have...

    How about this?

    I like it. I how would you know that it is the right spectrum of light?

    DIY LED lighting?

    Sorry I have taken so long guys but finally I got the lux meter out and tested it on a 3w led. 1/2 foot away from led: 3000+ lux (meter doesnt go above 3000) 1 foot away: 1800+ 1 & 1/2 foot: 800 2 foot: 475 I don't know what the angle of this particular led is but I would guess 80-90...

    DIY LED lighting?

    Very interesting link Tonser. Had I not already finished my LED project I would look into those led strips some more. Ceejay explained it well. I studied this for a few months last year and couldnt for the life of me find any PWM products which I could adapt to my led lighting to simulate...

    DIY PWM sunrise/sunset, moonrise/moonset LED lighting

    I have pretty much finished tweaking the setup now. I have removed all but one resistor which has increased the light output greatly. There is still a little more room for some brightness although I am struggling to work out how to do it. I would have to learn more about transistors and find an...

    DIY PWM sunrise/sunset, moonrise/moonset LED lighting

    I have been ironing out a few bugs in the project over the last week. I have a large voltage drop (2.5V) over each of the transistors which is making my led's dull. So I am going to play with a few things in the circuit and hopefully figure out a way to fix the problem without upping the voltage...

    DIY LED lighting?

    I am new to the DIY LED thing but I have been looking into it based in luminems. The ones I should be comming home to today are 3w 150 luminems. I go for 3000 luminems for my planted tank so I would try to work it out like that. I have a lux meter here so once I get some more brightness into my...

    DIY PWM sunrise/sunset, moonrise/moonset LED lighting

    I have finished my prototype tonight. It is set up to fade in for 6 minutes for sunrise, fade out for 6 minutes for sunset. Then fade into moonlight over 6 minutes and stay on for another 4 hours and then fade out over another 6 minutes. Here is a picture of the moonlight as close to how it...

    DIY PWM sunrise/sunset, moonrise/moonset LED lighting

    I bought the leds through Farnell. I beleive that they operate in the UK aswell. Here they are excellent. I buy something and receive it the next day , every time.

    DIY PWM sunrise/sunset, moonrise/moonset LED lighting

    Hi guys, I have finally got something to show you guys since I first mentioned it over 4 months ago. I started studying everything I needed to know (and alot that I probably didnt) in order to make a led setup which simulates sunrise/sunset, moonrise/moonset. So here goes, I will start from...
