My garland grow light garden bulbs run quite hot, I thought they were supposed to be cool? If I have my seedlings really close I think they'll Scorch?

i would email the ebay seller and ask if that comes with bulbs, also doesnt say tube length or wattage needed, but from the picture with dimensions its a 4 foot so will be 36w t8 tubes but do check.
look for daylight tubes or cool white but others will work too, on the box or bulb look for any of these 3 ways used to describe colour 860/865/765 - Daylight - 6000K- 6500K
Phillips, GE, Osram or Sylvania bulbs will all be high quality.
Warm whites are most common in hardware shops, some have cool white and daylight not so often.
T5 bulbs are a lot cheaper than t8 at least online, and they are more efficient while putting out more light per inch of tube.

It doesn't look like you get the tubes with it - which ones should I go for and who has the keenest prices?
Love, love, love this thread

Excellent thread. I'm going to have a go at making the light stand in BM's original post. I've got a heap of plastic pipe and T's, 45's, etc in the garage so will have a rake in the morning. Meanwhile, I've ordered one of these:
Kanlux ALDO 236R Batten lamp T8 linear fluorescent tube IP 20 indoors G13 8994 | eBay
Just need to pick up a couple of tubes and some chain.Last edited by amandaandherveg; 11-01-2013, 10:10 PM.

Originally posted by woody21 View PostCfl Bulbs do work well but i do prefer linear tubes as there is less wasted light as more light from the back of the bulb can be more efficiently reflected. you also lose light in the centre of the bulb as whatever light hits another part of the tube is lost and you cant get a reflector in there to get it all out through the gaps.
Those 30w bulbs produce 2000 lumens of light, which is the same as a 24w linear t5 so less lumens per watt. 6 more watts of energy to get the same amount of light out.
more smaller cfls like you have are good for covering larger areas and keeping small plants happy which is a better choice than a single high power cfl bulb.
cfl bulbs are harder to recycle too as you are throwing out a bulb and electronic driver, also if the electronics give up which they usually do well before the tube is dead its a waste of a perfectly good tube and hardly anyone recycles them either!.
with linear tubes you just replace a tube if it goes but they are very reliable and last years, or repair or replace the light unit if it goes (cheap and easy to repair them) and more reliable than the very poor electronics in a cfl.
The sunblazer 2ft 4 tube t5 light thats someone posted a link too in this thread is great value for i think it was £40.

I must admit reading all the positive comments in this thread, it seems that the technology has improved a lot since my efforts some years ago. It sounds like I really must give it a go again. It would be particularly helpful in getting those things going which 'flower in the first year from seed' if you only start them early enough. Thanks for the advice.

5 x 30w = 150w Daylight Energy Saving CFL SAD bulb E27 | eBay
As a trial as they can always be put to other use

Originally posted by BertieFox View PostMust admit after my experiments with daylight tubes I wouldn't bother again. The plants have to be so close up to the tubes to make any difference and even then I really couldn't notice much difference. I see you can now buy very cheap LED growlights, though a quick search about these got lots of negative references. Let's just hope that the sunshine and longer daylight hours will be soon with us again. Most later sowings catch up with all those things you have spent weeks and weeks coddling into life, and sometimes they do far better as they are healthier seedlings.
Im using 96 watts of T5 high output lights with the tubes 3.5 inches from the top of these chilli seedlings, the larger ones have been under lights for just 10 days after hatching in the unlit heated propagator
The tubes are old too and still working very well, they are osram 865 (6500k) daylight tubes and they used to work well growing aquatic plants even at 15 inches depth of water.
also my old tubes are much brighter than the cheap unknown brand tubes that came with a new lightwave unit i bought myself for xmas.. so cheap tubes are just a waste of electric go for sylvania,GE,osram or phillips.Attached Files

I don't have cheap overnight electricity - but my little tube is only 8w.

A timer is ideal so you can have them come on at night for the cheap electricity and off in the morning when the free light comes out

What are you lot like you've convinced me to buy another SAD daylight bulb - but this one is for the plants
