  1. @ Mobile, maybe I explained evil, the white LED SMD and power led have wavelengths very similar to each other regardless of brand. The datasheet can be found on the internet that confirm my words. The real difference between white LEDs from different manufacturers is the efficiency lumens / watt. As described previously warm white LEDs are similar in spectrum lamps phytostimulants, not perfectly cover the blue peak of chlorophyll but quietly covering the red peak extending the range also far red, this feature makes them unique. The LEDs give off specific chlorophyll a wavelength selective c
  2. The white LED technology is based on blue light that strikes a mixture of phosphorescent materials, depending on the blend will have the different colors, while the fluorescent lamps use an ultraviolet light to hit the phosphorescent material. The phosphorescent material used for the white LED emits the same wavelengths regardless of the type of the LEDs, can be power led, led smd or cob led, but the photometric graphs are very similar. I designed and built ceiling lights with white LEDs for Italian friends of and they too appreciate this technology, both as a result of cultivation and as bo
  3. OK for mixed 5 strips, you should also buy a dimmer, they are found on the net a few Euros, I was fine with the model enclosed in a small box of cream color, the model to 8 amps that's okay. Prompt
  4. The power needed to have the best lighting with only white LEDs is 65 watts total (warm+cool). relationship cool white / warm white 1:1 it is preferable to alternate the LEDs one warm and one cool, if you're not an expert in electronic welding, you can alternate 3 cool and 3 warm, cutting the strips every 3 LEDs. As far as other than white LEDs do not know what to advise you, my experience is only on white light. The led strips commercial red and blue are not specific for cultivation and are distant from the absorption peaks of Clorophilla, at this point I suggest a total white lighting.

  6. Hi Ptaah, can you give me the measurements of your terrarium? I do a quick calculation and I point you should have the power. the red and blue stripes are commercial ones or those specific to plants? Prompt
  7. 5050 LEDs are good for terrariums under to 50 cm high, while the 5630 can use them under to 60 cm, height exceeded this must orient on power led, if the terrarium is higher than 80-90 cm must be added to additional optical for power LEDs . I just wanted to point out that the phosphor white LEDs have applied to cover more shade than the classic fluorescent lamp 6500k - 4200k etc.., However are very close to fluorescent phytostimulants, especially warm-white LEDs. you can find my accomplishments in this section of the forum, both with power LED and also with SMD 5050. Lately I have also creat
  8. I use only white LEDs, warm white cool white, ratio 1:1. Under my ceiling were born 100% Roridula gorgonias, flowering sundew chrysolepis, I grow about 20 nepenthes highland / intermediate, drosera ascendens a diameter of 8 cm, all in good health. In the next periodic AIPC there will be an article written by me on testing the white LEDs on carnivorous plants. The eye wants its part and the plants they want their lights ! Prompt
  9. Another interesting test on 380nm UV light, it seems that this wavelength has had positive effects compared to other tests: http://www.lzi.lt/tomai/97%282%29tomas/97_2_tomas_str10.pdf Prompt
  10. LEDs uvb can be purchased directly from china: http://www.alibaba.com/trade/search?fsb=y&IndexArea=product_en&CatId=&SearchText=led+280nm I buy many components, LED lamps, etc. .. directly from Chinese companies Prompt
  11. a few questions: which receptor is sensitive to wavelengths UV and that benefice draws the plant? is the first time you experience the white LEDs? regards Gianni
  12. OK Karl, I use the technique of reverse, use LED warm white and cool white 1:1. In my experience in the optoelectronics led warm white are those that best serve the red spectrum, including the far red. While cool white LEDs are used to give an extra boost to the blue hue. I find it interesting the addition of UV LEDs that if I'm not mistaken should help strengthen the extreme range of the blue. In this regard wanted to ask the wavelength of the UV LED in nm ? As soon as I have time I will experience the addition of LEDs to red (730nm), which according to my research should stimulate the p
  13. Hello Karl, also I use white LEDs for my ceiling and I must say that the results are very satisfactory. Your work is very well done, I wanted to know the code of the LEDs and if the central LED panel is a warm white or cool white. thanks for sharing your work;) Prompt

  15. Ok! I searched the internet and in fact there are red and blue smd led for cultivation. But there is a technical problem to build a spotlight as those made by me. Prompt
  16. Ok! I purchased two spotlights, one cool white and one warm white. Then I unsoldered and soldered chips and I created the custom spotlight. In the market there are only mono color. They are also not knowledge of smd led red and blue suitable for cultivation. Prompt
  17. For the moment I am not interested the red LEDs and blue for growth, with the ceiling light 100W total white, I'm having very good results on various species of carnivorous plants. As soon as possible put photos in new topic. For this ceiling, the total cost about 20 euro. For a 7W single spotlight, the cost is about 5-6 Euro, excluding the work of customization. Prompt
  18. I have little experience with smd led, of course the quality is lower than the power LED. I also think that the problem you're referring to is shown waterproof led strips, in fact they use a bath of polymer (usually silicon) which over time can lose transparency. However, for terrariums as high as 60cm smd led these are good, there are 5630 smd type that are more powerful than the 5050, but are more expensive. In addition, I also found for smd 5050 lens 80 degrees and this is wonderful! For this ceiling, the cost of aluminum , spotlights and two screws no more than 20 euro, it seems a goo
  19. Meet my new realization, the total white ultra slim ceiling. Use smd led, like 5050, I just mixed the LEDs for each spotlight, warm white + cool white, ratio about 1:1 the small terrarium measuring 35 * 21 * 23h cm here are the pictures: the original cool-white spot the custom spot, warm white + cool white the rear spot the custum spot light the custom spot - front light the ceiling front view the ceiling with two custom spot light - other view the ceiling and terrarium the first test - on the center the first test on the corner for the moment this is everythi
