clip on lights?

Is there any good clip on lights that i could get for extra lighting for my plants so i dont have to get a whole new light fixture? something that dont cost 100+ lol

I use constution clip ons from walmart $6.98 each with a 100 watt screw in 6500K CFB (2 for $6)

with the cfb bulbs it say like 13 watts used but output is 60...so does that meen it adds 60 watts or 13 watts for my plants??? since im trying to get 1.5 watts per gallon

From what I have heard you use the 13 watt rating to figure your wpg. I have 2 of the 100 watt equivalent bulbs on my 29 in an old reptile light fixture and it is ver bright an my plants are doing great.

dang i was hoping it would be the other way..i would think that would be hard to figure cause it is putting out the equivalent of 60 watts ...13 and 60 is a big diff

26W us being used and bulb puts out 100W

the part that dont make sense is the lamp says nothing over 40 watts or if you use a cfb nothing over 13 watts...LOL guess the lamp sees that 13 watts being actually 60 LOL

That's why I use the construction clip on rated for 100w
