    Another update, looks like the bulb was faulty/used or something. It burned out after 3 hours of use today :| Google search says the smokey smell is a sign the bulb is burning out, also was taking awhile to glow which is also a sign its going to burn out, so I guess they sent me a cruddy bulb. Darn.

    Back into the box and to the recycling.

    Sashoke, may I suggest going for something without mercury on your next attempts to avoid any further panic. lol

    If you plant on replacing it with another fluorescent in the same fixture, then here is what I would use as an equivalent: http://www.amazon.com/EcoSmart-Equiv...s=a19+led+grow

    Bulbs with around 5000-65000K light spectrum are fine for growing & comparable to the fluorescents. There are numerous high end grow-lights, but the link provided is an affordable alternative.

    Definitely wont be buying CFL anytime soon again, Ive had enough stress for one day.

    Would the 450 lumens on those bulbs be good enough? Wouldnt I have to float those just a couple of inches above the plants to get much out of such a low lumens count?

    I believe that lumens are unimportant when it comes to plant growth but I'll look into this & add as its been a few years. But those bulbs don't produce much heat if they'll be close.

    Lumens don't directly quantify the wavelengths responsible for plant growth, but as long as you compare apples to apples (or for example CFL to CFL or LED to LED) it can be useful.

    Its a very old tree, and its big enough to where just trimming it wouldnt be enough, so I think supplemental lighting for Summer would be a better thing to do. I like that tree afterall.

    I may have been wrong, & right. lol
    Lumens measure the amount of light but not necessarily the amount of usable light for plants. But, generally you do want more lumens when attempting to cover a larger area with more depth. The color temperature is more important & what is the best to usually go on when looking for full spectrum lights in the 5000-65000k temp range... unless you buy your own LEDS & make your own fixtures which I have done in the past. You can then selct the best possible PAR when buying single leds which measures the light energy available for plant use & isn't always listed. If you really want to get technical then you would go with an array of lights on the spectrum; but, just as standard fluorescents work fine, most others in that same range work just as well.

    Some of the floodlights by the same brand or in the same category are listed par20 & 30 which are known to be great as plant growlights & coral growlights. Those lights I listed don't have a par rating so it would be a guess but I would assume they would work just as well if not better than a comparable fluoro based on experience with both. I may have confused more than helped. lol
