Well I have used all sorts of light over the years & I was using a 250w metal halide last year then I went to T5s.
I still have 120w of fluorescents, the led is placed above the foreground as a supplement & to test its effect. I was in B&Q today & I noticed that they now sell a range of replacement GU10 bulbs, I bought a 3.7w 3 xLED bulb. Cost about £11.00 & seems to be very efficient!! Previous B&Q 1.1w LEDs that I have bought were not very bright but this one seems to have three very bright diodes in the bulb & really does produce a bright light. (B&Q = hardware store) |
